It's been ten years since Android was first outed by Google, and back then it was hard to imagine the sheer number of apps we'd have today.

There are apps for everything, and many of them are completely free, meaning you're just a few downloads away from supercharging your smartphone at no extra cost.

• What's the best phone of 2017?

Admittedly, the huge quantity of apps doesn't mean they're all quality - far from it in fact, and finding the good ones can be tough. 

There are tools and techniques to help, with various lists in the Play Store providing you with Editor's Picks across a range of categories, new releases and even apps that are specifically recommended for you based on your previous installs.

You can also hunt out apps that are similar to your favorites by searching for an app you have and seeing what else comes up.

And checking out user reviews and ratings can save you from downloading a dud of an app.

But even with all that, the sheer number of apps on Google Play means many of the best can often get lost, while weaker ones sometimes rise to the top.

So to make sure you never install a duff app here's our selection of the best you should install right now - each one carefully chosen to ensure you'll have a whole suite of fun, engaging and, dammit, useful apps on your phone or tablet.

New this week: Datally

Ever wonder where all your mobile data is going? Datally can help answer that. It’s an app made by Google that not only tells you how much mobile data you’ve used over the last day, week or month, but also breaks down which apps are using it and how much they’re consuming.

That’s handy, but it’s something that a lot of other data monitor apps do too. Datally has a few extra features though. For one, there’s a data saver mode, which blocks apps of your choice from using data when you’re not connected to Wi-Fi. That’s especially handy if you find one is a big drain and you don’t need constant access to it.

There’s also a list of nearby public Wi-Fi networks. The app shows you how far away they are, pinpoints their position on a map, and tells you whether they’re password-protected, so you can more easily seek out a suitable connection.

Datally is a Google app, so it’s unsurprisingly polished and simple to navigate, all of which makes it a very worthwhile freebie.

Storyboard is an experiment – or “appsperiment” as Google calls it. It’s very simple, but not quite like any other app we’ve come across.

Simply load a video and Storyboard will turn it into a comic strip by automatically selecting and arranging frames and adding a filter that makes it look more comic-like.

If you don’t like the result you can swipe down to refresh and get a different layout, filter and selection of scenes. Keep doing this until you find one you like, then tap on it to save or share it.

The results are often good – after a few refreshes we usually found a result we were happy with – and it’s very quick and easy to use.

We kind of wish it was a bit less simple and actually gave you control over the layout and filters rather than randomizing it, but maybe one day we’ll get that when it’s less of an appsperiment and more just an app.

Onetap Glitch is a simple app that does one thing and does it well. In short, it lets you add a glitch effect to your photos… with one tap.

Actually, there’s a bit more to it than that. There’s a handful of different glitch filters to choose from, and you can alter them by adjusting the RGB shift, intensity, brightness, thickness and contrast.

Whatever you do you’re typically left with a quite stylish effect, which you can then save to your gallery or share to other apps.

It works best with pictures of people, and any image that’s overly busy can look too much of a mess. It’s not an effect you’re likely to want to use very often, but it’s a fun one to have on hand.

Did you know that the best time to buy a car is at the end of the month, since salespeople have quotas to hit and are more likely to cut you a deal? Or that you can get gum out of hair by dipping it in coke? If you had Life Hacks you would.

This appropriately named app has hundreds of hacks spread across various categories, such as ‘Money Savers’ and ‘Study Boosters’.

Tap on a category and you’ll be shown a selection of cards, each of which has a life hack on it. The bottom of each card also has the option to favorite, copy or share it, so you can easily build up a library of useful hacks or share them with your friends.

New hacks are also regularly added, so you won’t run out of things to learn. Some of the hacks are clearly aimed specifically at US users as they’re related to businesses like Walmart and Wendy’s, but most of them could be useful wherever you are.

Hitlist is designed to both find cheap flight deals and give you ideas of where to go. You start by selecting your home airport, then you can select a destination and the dates you want to travel, then get results sorted by price.

So far, so familiar, but Hitlist lets you select a range of dates rather than a specific flight day if you’re prepared to be flexible in order to save money, or you can even enter no dates at all if you’re happy to travel at any time.

And that’s just half of the app. The other half is about discovery. Hitlist will highlight various locations and events, such as the best cities for New Year’s Eve, and the best places for photography. Tapping on any of these will let you drill down to specific locations and then look for flights.

If you save a location you can also get alerts from Hitlist whenever the flight prices drop, so there’s a lot here, whether or not you know where you want to go.

Smiling Mind is a meditation app for everyone, and when we say everyone, we really mean it, as there are meditations specifically designed for various age groups and situations, from kids of 7 through to adults, from office workers to athletes, from those new to meditation to those who’ve been doing it for years.

There’s also resources for anyone trying to teach meditation in the classroom, and whatever your age or situation you’ll find meditations of varying lengths, from as little as around one minute, to around half an hour.

The app will also keep track of how many meditations you’ve done, the total duration and on what days, and if you want to share the app you can set up sub profiles, so everyone has their own accounts.

Unlike many meditation apps, Smiling Mind is also completely free. There’s no subscription, no in-app purchases and not even any adverts.

Sticking with the same wallpaper for too long can get boring, but if you’re anything like us you rarely bother to change it.

With Smart Wallpaper you can set up a selection of wallpapers to cycle between, so once it’s set up there’s little to no need to ever manually change your wallpaper again.

Smart Wallpaper can change your wallpaper after a set time period, but it can also do it based on the day of the week, the month, the weather or even the Wi-Fi network you’re on.

The app itself has a number of wallpapers to choose from, but they’re not sorted into categories so it’s not the best way to browse for wallpapers.

However, you can also import them from your gallery, so just find a collection you like from whatever source you like and then send them over to Smart Wallpaper, so you’ll never again have to look at the same picture for too long.

Replika is a hard app to categorize. It’s an AI that you can talk to, but it’s more than just a gimmick and there’s purpose to the conversations.

It will often ask you things like how your day’s going, how you feel and what the highlight of your day has been, and by answering these questions you can build up a sort of journal, which you can then search through, as there’s a part of the app that sorts your responses by date.

Of course, you could just use a journaling app, but we found the prompts of the AI and the feeling of having an actual conversation more appealing than just writing things down.

Many of the questions asked will also prompt you to focus on positives, which in turn could help you be more positive.

Replika can also act as a confidant - ‘someone’ you can talk to about anything, at any time.

And the more you talk to Replika, the smarter it gets. It learns your responses and becomes a bit more like you over time, as well as allowing you to upvote or downvote anything it says.

Chances are you already have some kind of file manager on your phone, but Files Go is still worthy of attention, as it’s made by Google and has many rivals beat.

There’s two parts to it. First, the ‘Storage’ section which highlights all the ways you might be able to clear space on your device, such as by deleting duplicate or large files, moving files to your SD card and deleting rarely used apps.

Then there’s the ‘Files’ section, which is a file explorer, letting you dive into the folders on your phone so you can find, open, rename, delete or share specific files.

The whole app is colorful and easy to navigate as well, with an interface seemingly inspired by Google Now’s cards.

Zyl claims to be the first photo gallery managed by an in-app AI. We don’t know whether that’s true or not, but it’s certainly a useful way of managing your photos.

Zyl is especially handy if you want to clear space on your device, or just get rid of rubbish shots, as that AI we mentioned can find and delete blurry shots, as well as duplicate or similar photos, even choosing to keep the one that it thinks is best.

And its judgement is generally quite good, but you get to confirm before deleting anything, and even then photos can be recovered for thirty days in case you change your mind, so there’s no danger of losing your favorite shots.

Other features of Zyl include the ability to create collaborative albums that several people can access and add to, and for Zyl to automatically create albums from your pictures – though this didn’t work very well in our tests, as while some of the suggested pictures were similar, others seemed quite random.

Still, Zyl’s ability to clean up your gallery is enough to make it worth a download if your photo collection is getting out of control.

Having been around on PC for a while now, Microsoft Edge has finally arrived on Android, albeit in beta.

Microsoft’s replacement for Internet Explorer is surprisingly polished, and especially useful if you run it on both Android and a Windows 10 computer, as you can send content between your phone and your PC.

You first need the Fall Creator’s update on your computer, but then you can simply tap a button at the bottom of each webpage on your phone (or hit ‘Share’ then ‘Continue on PC’) and have the page load on your desktop.

Your favorites and reading list are also automatically synced between devices, giving you further incentive to make Microsoft Edge your one and only browser if you’re going to use it at all.

There are also handy features such as voice search, and a ‘Reading View’ which reorganizes pages to make it easier to focus on the main text.

If you already use Edge on your computer then the Microsoft Edge app is worth having, but if not there’s probably not enough here to convince you to switch browsers.

That said, it’s worth a look if you’re not getting on with your current one - just be aware there might be a few bugs while it’s still in beta.

And yes, you can switch your search engine from Bing to Google.

Live wallpapers can look great, but they can also drain your battery and hog your RAM… the good news is Material Islands - Wallpapers does neither.

That’s because rather than being constantly animated it’s just updated several times a day, showing a minimalist island changing from dawn to dusk.

And there’s more than one island in this app. You can choose from the mysterious ‘Isle of Easter’, the frosty ‘Isle of Ice’ and around 10 others, or choose ‘daily random isle’ and get a new one every day.

More islands are likely to be added over time, and you can customize the experience to an extent – choosing the time period during which each version of an island is shown, or just setting a static wallpaper if there’s a particular scene you want at all times.

The world is full of weird and wonderful fonts, but identifying them isn’t always easy. That is, unless you have WhatTheFont.

Then you can simply take a photo of the font you’re curious about, or grab an image from your gallery, and WhatTheFont will analyze it and show you a selection of similar fonts.

The fonts it shows you may or may not include the actual font that you photographed - we’ve had slightly mixed results on that f(r)ont - but all the selections are usually close to it.

You can type out any word or phrase in any of the fonts it comes up with to get a better idea of how they look, and then if you really like them there’s a link to buy.

Other than the fact that WhatTheFont seemingly doesn’t have every single font in its database, our main complaint with it is that it won’t save your previous searches and nor can you favorite fonts to return to later, so if you want to remember one you’ll have to write the name down.

But as a freebie – at least until you succumb to the urge to splash out on the fonts you find – it’s a handy app.

Messenger Lite is designed to minimize the amount of data you use when sending and receiving messages on Facebook.

It’s an official app and likely designed with developing countries in mind, but could be useful anywhere if you have a restrictive data limit or an iffy connection.

Messenger Lite works on all networks, even 2G, and if there’s no signal when you send a message it will automatically be sent as soon as there is one.

It uses less data than the main Facebook Messenger app and also loads faster and takes up less storage space. All this efficiency should also mean it’s lighter on battery usage, and indeed it was in our tests, though the difference is small, yet Messenger Lite has many of the core Messenger features included.

You can send messages, including pictures and stickers, have group chats, see who’s online and make or receive voice calls.

Some features are absent, most notably video calls, but for the basic Facebook messaging experience this should have you covered, and it’s got a less cluttered interface than the main app too.

Eyecon is a replacement dialer and address book for your phone, and it’s impressively fully featured and good looking.

Contacts are automatically assigned a profile photo if it can find one on social media, such as WhatsApp or Facebook, and you can quickly call anyone with a long press, or access a menu for that contact with a tap.

From the menu you can head to their profile, call or message them, and if you connect other services you’re not limited to just SMS, as it can also provide shortcuts to the likes of your WhatsApp and Skype conversations.

Further speeding up communication, Eyecon also lists your most contacted friends at the top, and after a call with someone who’s not in your address book Eyecon will even suggest a name and photo for them, so you can add them to your contacts with a tap.

Eyecon won’t change the way you use your phone, but it’s a system that’s a lot like how Android used to operate on many phones, especially HTC ones, so if you long for those days it’s worth giving a try.

Want to watch TV with your friends? Too lazy, busy or spread out to meet in person? Then Rabbit – Watch Together could be for you.

While it can’t quite replicate all squeezing on the same sofa or going to the cinema, it does give you a private chat room for you and your friends to talk in while you all watch a video from YouTube or the web (but not from paid services like iTunes or Netflix).

The video is automatically in sync for everyone, so you don’t have to awkwardly get everyone to hit play at the same time, and you can have up to 100 people in the room – which is one way in which this can top a real-world movie night.

Rabbit also allows for voice and video chat, and you can even make your room public if you’re happy for strangers to join your viewing party.

If you’re a user of Amazon’s ebook store then you probably already have the Amazon Kindle app, but if not it’s worth getting, especially as it’s just been overhauled to make it slicker than ever.

As before, the app gives you access to your Kindle books on your phone or tablet, as well as access to the store - so you can buy more digi-tomes - but it’s now got a new look, with larger cover art and a re-designed interface that makes it faster to get into your books.

There’s also a new light theme joining the dark one, and the app will soon be improving further, as Goodreads integration is on the way, which will allow you to rate your books and interact with that community from the Kindle app.

The name of this app is slightly unwieldy, but the app itself isn’t, giving you a fast, simple way to not just convert one currency to another, but to view how it converts into as many as nine other currencies, all on a single screen.

And it will almost certainly have the currencies you want, with all world currencies accounted for (including Bitcoin) and precious metals, such as gold and silver.

You can also view graphs of currency fluctuations over time and choose which rate providers you want to use. There’s even a built-in calculator built-in...for some reason.

This might all make Currency Converter Plus Free sound bloated, but it’s not. It boots straight into the conversion screen and remembers which currencies you last wanted to convert to and from, so you can very quickly do new conversions with those monetary forms.

The graphs and other extras are there if you need them, but the interface is focused on getting basic conversions done fast, so it’s ideal even if you just use it occasionally. It’s not the prettiest app around but it’s deeply functional.

While we’re ever-more connected online it seems like we’re often less so in person, and many of us have hardly even met our neighbors.

Nextdoor aims to make doing so a lot easier, by creating a social network populated by the people who live around you.

You need to verify your address to even join it, which can be done by either entering your phone number (if the billing address is where you currently live) or by having a code posted to you and then entering that (so the people who it says live nearby really are) and once verified you can post things which will be seen by those who live nearby.

People typically use it to advertise, or to get the word out about missing pets, local crime and the like, but you can also get talking to people you might live close to but never talk to or even see in day to day life.

As everyone uses their real title it’s also a handy way to remember your neighbors’ names if that’s something you struggle with.

Ultimately, Nextdoor makes communities feel closer, smaller, and, well, more like a community, which can only be a good thing.

Discord is a voice and text chat app built specifically for gamers. It’s great for communicating in-game, but also houses numerous gaming communities and acts a bit like a huge group chat for them, or rather, a series of group chats, spread across different topics.

You could equally think of it – or at least the messaging part of it – as being like a real-time forum, or to gamers what Slack is to work.

Images and videos can be shared, there’s one-to-one private messaging, plus push notifications for any mentions, so you won’t miss messages directed at you.

You can also show whether or not you’re online and tweak what you’re notified about and the colors of the app, and it’s cross-platform, so you can chat with people who are using Discord on a desktop or iPhone.

Basically, if you use Discord on another platform it’s well worth having the Android app. And if you don’t but you regularly play online games with a group, or just like talking about games, then it’s also worth a look.

There are plenty of apps for checking your Wi-Fi speed, but Wifi Analyzer does something a little different, telling you what channel your Wi-Fi is on and, importantly, how crowded that channel is.

This is especially handy if you live in a flat or somewhere else where there are lots of nearby networks, as sharing a channel with lots of other networks can hamper your Wi-Fi’s speed.

Wifi Analyzer also gives every channel a star rating and recommends which ones you should use, as well as having a tool to check your signal, so you can see what impact changing the channel has actually had.

Sadly, you can’t actually change the channel of your router from within the app - that’s understandably beyond its capabilities and needs to be handled by your router’s web interface.

But if Wifi Analyzer finds that you’d be better off on another channel then it’s a change that’s worth making. After all, you’re paying for a certain internet speed, so you might as well do everything you can to make sure you get it.

You probably already have some sort of news aggregator on your device, but if you like sharing interesting stories with other people then Squid could have it beat.

That’s because Squid lets you annotate stories before you share them. You can underline, circle and highlight sections in various colors, add text of your own and even add stickers, then send the story off in an email or social media message.

Other than being able to leave your mark on the stories you find, Squid is fairly conventional, but quite polished.

You can pick from a range of topics that you’re interested in, such as music, lifestyle or politics, then get a constantly updated feed of relevant stories.

You can switch to a topic-specific feed with a swipe, block sources you don’t want to see with a few taps, and switch to a reader mode (which ditches most of an article’s adverts and other unnecessary content) with ease.

Notin is a simple app, but a useful one. Simply type out something you want to be reminded of, tap the plus button and it will be sent to your notification shade, so you can always see it on your lock screen or when you swipe down from the top of the screen.

Got more than one thing to remember? Type something else out and hit the plus again to get more than one notification.

That way, rather than having a reminder pop up at what may end up being an inconvenient time, you’ll always just see it when using your phone, so you’ll never again forget that you need to buy milk or get married.

Once you’ve done the thing you need reminding of just swipe the notification away, as you would with any other notification.

There are two potential weaknesses with Notin. One is that it’s entirely too easy to swipe away a reminder without thinking, the other is that if you have lots of things on your to-do list your notifications screen could quickly become cluttered, so Notin is best just for reminding you of one or two important things, while keeping your full list elsewhere.

Still, as a completely free tool Notin is well worth remembering.

Whatever you want to send and wherever you want to send it, Send Anywhere is likely to be a speedy, simple solution.

The app is completely free and supports a wide variety of file types, from audio, video and images, to apps (APK files), documents and beyond.

Simply select a category, then select a file (or multiple files), then tap the send button. You’ll be presented with a range of options for sending, including a code which needs typing into the Send Anywhere app or website on the recipient device, a URL you can paste in, or a QR code you can scan.

Alternatively, if it’s a device you’ve shared with recently you can simply tap on it to get the transfer started.

Send Anywhere works across iOS, Android, PC and Mac, files are encrypted and it’s completely free. There are adverts, but they were never intrusive in our experience.

Material Notification Shade is ideal if you want to give your notification shade a makeover. For one thing, it changes the look of the screen, letting you choose between several themes and numerous colors, and whatever you choose it results in a smart, stylish look. It also includes custom animations for when you interact with notifications.

For free you get all that, essentially giving you the power to heavily customize the general appearance of your notification shade.

But Material Notification Shade goes further if you shell out on the $1.99/£1.89 IAP, adding the ability to also change the number of columns and rows it uses, and the number of tiles visible on your first swipe.

It doesn’t add any real functionality, but it looks good and if, like us, you swipe down your notifications screen a lot, it makes a nice change.

If you live in a city then chances are there’s a lot going on, and with Fever you have all you need to find the best of those things, and in many cases even get discounted entry prices.

The app, which currently covers London, New York, Barcelona, Madrid, Seville, Valencia, Málaga and Bilbao, first asks you which city and what type of events you’re most interested in, then presents you with a curated feed.

Alternatively, you can head to the ‘Discover’ tab to view other event lists, focused on a specific time (for example the weekend) or type (such as dining or family).

Tap on an event and you’ll see full details of it, including a map, and have the option to share it or buy tickets, which are then stored in the Fever app itself.

There are other apps a bit like Fever, but if you’re in one of the cities it covers it’s a slick, all-in-one way to keep on top of what’s happening around you.

If you need help remembering to check your to-do list, then Memory Helper is one app you’ll want to remember to download.

It essentially is a simple to-do list, but the twist is that it will display whenever you wake up your phone, so you’ll be constantly reminded of the things you need to do throughout the day.

You might find that annoying, but if you tend to forget to otherwise check your to-do list then it can be very useful.

That feature aside, Memory Helper is simple but well designed. Entries on your list can be cleared with a swipe and recalled with a tap, you can drag entries to re-order them, change the color scheme, text size and alignment and choose whether you want the list to pop up before or after your lock screen.

You can also choose whether to always display Memory Helper when waking up your phone, or only when there’s actually stuff on your to-do list – we recommend the latter.

It’s best when there are only a few things in the list, so you can see them all at a glance. As such Memory Helper may not replace your main to-do list, but as a free way to help you remember really pressing things it’s extremely handy.

If you like your weather with a side of humor then you should check out What The Forecast?!!, which provides generally negative (or some would say realistic) commentary on the current weather, in the form of a short humorous sentence.

It’s reminiscent of the iOS app Carrot Weather, but it’s laughing with you, rather than at you, and more importantly is actually available on Android.

Beyond the commentary, which apparently includes over 6,657 phrases, you can get 7-day forecasts and details on humidity, sunrise and sunset times, wind speed, the moon and more.

It’s all fairly standard weather app stuff, but delivered with more personality than usual, and as the actual forecasts are pulled from Dark Sky, What The Forecast?!! should be just as accurate as your current weather app of choice.

Hurry is a simple countdown timer showing you how many days, hours, minutes and seconds you have left to a given event.

You can set up as many timers as you want and view them in the app, as widgets or even pin them to the notification bar. When using the app or widgets you can make them a bit more visually interesting by giving them background pictures either suggested by the app or pulled from your photo gallery.

More than one image can be assigned to each countdown, in which case it will change over time. You can also get notifications to remind you that an event is coming up, and, somewhat less usefully, play a multiple-choice quiz game where you have to guess how many of a given thing could happen in the time left.

We can’t see many people spending long on that, but if you’ve got a big event coming up then having a countdown timer is a lot more exciting than just sticking it in your calendar.

Tinycards, from the makers of Duolingo, has taken a long time making the jump from iOS to Android, but it’s finally arrived, and is set to give you another way to improve your language skills.

Link it up to your Duolingo account and then Tinycards will give you a selection of flash cards based around the words and languages you’re already learning.

These will sometimes take the form of a picture, in which case you have to say what it’s a picture of in the relevant language. Other times the card will show a word or phrase in the language you’re learning, which you’re to translate to English, or the phrase will be shown in English, in which case you’re tasked with translating it to a foreign language.

Like the main Duolingo app answers are sometimes multiple choice, while other times they must be typed, and you can unlock new sets of flashcards as you progress.

It’s essentially a simpler, even more bite-size form of language learning than Duolingo offers and is best used in combination with that app.

But you can also create your own cards and decks if there’s something specific you want more practice at, and interestingly you’re not just limited to languages, as history, maths, science and more all have their own flashcard decks too.

Got 60 seconds to kill? Raccoon could be an enjoyable way to do it. Not just a cute woodland creature, Raccoon is also now an app where people post 60-second videos of them telling a story from their life, or talking about an experience.

These are sorted into categories, such as travel and work, and theoretically the stories will all be interesting, funny or inspiring. Of course, as anyone can add a video the quality varies, but you can find the best by choosing ‘featured’ videos or looking out for those with a lot of likes.

That’s half of Raccoon. The other half is posting your own 60-second video. If you have a specific story to tell you can just hit record and start talking, or if you need inspiration you can select an option that asks you a question or gives you a nudge, such as ‘share an interesting fashion story from your life’, and then hit record if you’re up to the challenge.

It’s a fun way to hear or share bite-size stories, and while content is currently a bit limited, if Raccoon takes off there should soon be no shortage of stories to choose from.

While many of us have moved to streaming music, there is still a place for locally stored music on Android, and Phonograph is one of the better players.

Phonograph puts aesthetics and ease of use first, so it’s always pleasant to operate. The app has a Material Design look that fits with Google’s vision of Android, but it’s also packed full of album art and color, so there’s never a dull screen.

You can also customize the colors and overall theme and look of the app, while the color of the main ‘now playing’ screen will change based on the album artwork of the current track.

The layout is simple too, with your music library sorted by song, album, artist or playlist, and you can switch between views with a swipe, while most other options are no more than a tap away.

Although not as feature-packed as some players, Phonograph has a number of handy extras and toggles, like gapless playback, information and images pulled automatically from Last.fm, a sleep timer, widgets and lock screen controls.

There are plenty of icon packs available to help you change up your app icons, but what if you want a bit more control, or just want to tweak rather than replacing an icon? That’s where Adapticons comes in.

The app lets you create or adapt your own icons, picking first the icon that you want to customize, then choosing from a variety of shapes and colors, changing the size and rotation and even optionally changing the text displayed under it - which could be handy if for example you know an app by a different name than what it’s listed as.

Although you can get Adapticons for free, you might want to splash out on the $0.99/£0.99 IAP if you plan to customize a lot of icons, as this unlocks loads more shapes, lets you import icons from your gallery, gets rid of adverts and lets you customize more than one icon at a time.

If you’re looking for an incentive to get out and walk more then Street Hunt could be just the thing. Choose a distance from your location and then Street Hunt will give you a target to reach that’s roughly that far away.

The twist is that it doesn’t tell you the address or directions, it simply gives you a Google Street View image of it.

From there you’ve got to either work it out from the photo or simply start walking, at which point Street Hunt will tell you whether you’re getting closer or further away.

You can see approximately how far you are away from the destination using an indicator on your lock screen, so you don’t have to keep opening the app, and you can also get periodic vibration cues – with a single vibration telling you you’re getting closer, while two mean you’re moving further away from your target.

Completing a hunt gets you points, and leaderboards let the competitive among you compare their score with friends or the world at large.

It’s a fun idea, hampered only slightly by the fact that destinations are chosen purely based on distance, and as such may not always be easily accessible, but the developers claim to be working on smarter destination selection.

Like a digital version of a scratch map, Travellite lets you tell the app which countries you’ve been to and then see them highlighted on a map of the world.

There are statistics to go with it, saying what percentage of each continent and the world as a whole you’ve travelled to, and there’s a journal component, so you can log your adventures with text, a date and optionally a photo.

That component doesn’t feel as fully-featured as some other journaling apps, but there’s something appealing about seeing an ever-growing map of the places you’ve been, and the app is easy to use, letting you see a long list of countries and simply tap the ones you’ve been to.

There’s not a huge amount to it, but for free Travellite is well worth a look for anyone who’s seen much of the world, or wants to see more.

One screen timeout duration does not necessarily fit all situations. For example, if you’re reading an article you might want a longer timeout than normal, so you don’t have to keep tapping the screen to stop it going dark.

Yet timeout controls are often hidden away in sub-menus of the settings screen, so regularly changing the duration can be a bit fiddly.

Not with Caffeine though. This app adds a quick settings tile to your notifications pull-down, which you can tap to change the timeout duration. One tap will set it to 5 minutes, a second to 10, a third tap makes the timeout 30 minutes, a fourth disables screen timeout altogether and a fifth disables Caffeine (so that whatever timeout duration you had set outside the app will kick back in).

Caffeine even displays a handy countdown next to its tile of how long until your screen will shut off.

It’s simple. So simple in fact that Caffeine doesn’t even have an app icon. To ‘launch’ it you instead long press on the quick settings tile, but all that gives you is instructions for using it and the option to uninstall.

Much like the drug it’s named after, Caffeine won’t help everyone, but if you’ve ever wished for speedier access to your screen timeout controls this is the app you’ve been waiting for.

Festivals can be sociable places, and Radiate helps facilitate that by putting you in touch with other people going to the same festival as you.

Select the festival you’re attending and you can access a forum dedicated to it, where people chat and arrange meets and lift shares.

There’s also a Tinder-like component where you can swipe over pictures of fellow festival attendees to say whether or not you want to chat with them – and if you both say yes, a private chat opens.

So whether you’re braving a festival on your own or just want to meet some new people while you’re there, Radiate can help, and it’s got a large selection of festivals in both Europe and the US.

Radiate also has festival information, including line-ups and maps, but nothing you won’t find elsewhere. Really it’s all about the social side.

Referred to as the Instagram of text, Boldomatic is a social network of sorts, where you can post a sentence or two and send it out into the world.

These tend to be a mix of original statements and poetry, along with quotes from other people, so it’s more about creativity and inspiration than sharing the sorts of thoughts and feelings you might on Twitter or Whisper. But really you can write whatever you want.

You can stay anonymous or not, get comments on your posts and follow, like and comment on other users posts.

You can also send direct messages, and cross-post your content to other social networks such as Facebook and Tumblr from within the app.

Boldomatic is an app that in some ways is hard to pin down. Some writers aim to offend with their posts, others to make you laugh, or think, but it’s easy to find just the good stuff by filtering by what’s popular.

Or just browse at random and take a deep dive into the regularly weird, sometimes annoying, often inspiring community that’s built up around it.

Offline Survival Manual is a comprehensive guide to everything you need to know when you’re in the wilderness. And it’s saved offline, so you’ll actually be able to access it in the middle of the forest / desert / jungle / your garden.

From skills, such as how to start a fire or build a shelter, to helpful advice, such as where to look for water in various environments and which plants are poisonous, it’s all covered.

On top of that is information the things you should take with you in certain places and how to deal with different types of weather or hazards, such as crossing a river - so most things you might want to know are covered.

There’s loads more besides, split into various categories which you can jump between with a tap, and as there’s everything from the basics to more advanced things, Offline Survival Manual is a guide for everyone. It’s also completely free.

There is a lack of polish in some of the presentation – typos and long walls of text for example, with few images to break it up in many sections. Then of course there’s the fact that having a survival manual on a device that can run out of battery may not be the best idea, so you might want to bring a paper guide too.

But you’ll presumably be taking your phone with you on any adventures, and Offline Survival Manual could prove an indispensable addition - who knows, one which might even save your life.

Tubio is a slick, easy way to get video and audio content from your phone to your television. It works a lot like a Chromecast (and indeed you can cast to Chromecast) but sources that don’t officially support big-name streaming services also work with it.

It’s also handy if you’ve got a DLNA/UPnP/AllShare-enabled smart TV that doesn’t work with Google Cast or similar, as this is an easy alternative to buying another piece of hardware.

Tubio can also cast to Amazon Fire TV, Roku, Nexus Player, Android TV, Xbox One and Xbox 360, all with the press of a button – your phone just has to be on the same Wi-Fi network as them.

The app has a built-in web browser for finding content and full playback controls once you start streaming. You can also navigate away from the app and keep using your phone as normal without interrupting the stream.

There’s a pro version for a one-off payment of $2.99/£2.49 which gets rid of adverts and ups the playback quality, but we’d recommend testing out the free version first, to make sure it suits your needs.

It’s not often that Google’s apps come to iOS before Android, but Motion Stills did, as it was designed to stabilize Live Photos, so they’d come out smoother. Now though it’s out on Android too, letting you shoot a short video clip which the app stabilizes.

Clips that you shoot can be saved as a video or a looping GIF and then shared on social media, and Motion Stills also lets you use a ‘Fast Forward’ mode, which will condense up to a minute of footage into a shorter clip. This too is stabilized, to keep it smooth, and you can pick the playback speed.

Motion Stills only works for new footage – so you can’t import and stabilize anything you’ve already shot (though if you just want to turn old footage into a GIF there are plenty of other apps that will do that).

But for anything new you shoot Motion Stills is a great way to make a GIF or short video and ensure footage remains smooth. It’s fast too, as footage is stabilized in real time, so you don’t need to wait for it to process your clip, and it’s completely free.

There’s a lot more to the rising and setting of the sun than you might have realized. There’s the period this app is named after for one, which is famous among photographers as having particularly soft light.

But there’s also blue hour, nautical twilight, astronomical twilight and others, and this app will tell you the times and duration of all of them, so whether you know all about these periods and want to be able to catch them, or are simply curious to learn more, Golden Hour can help.

Handily, it’s also got a map, which shows you the direction of the sunrise and sunset, so you’ll know which way to look (and this can also help with knowing where to put plants and things in your home, based on where will get the most sun).

You can also set up notifications for upcoming sunrises, sunsets and golden hours, and the app is completely free.

Blackpills is home to various shows which you can stream on your phone or tablet. All of its content is original, and it covers numerous genres, such as comedy, thriller, sci-fi and more.

The quality of the content is generally quite high too, and some things even have big names involved, such as James Franco.

It’s also all short, usually coming in at roughly 10-15 minutes, so you should easily be able to find time to fit an episode in wherever you are and whatever you’re doing.

There’s not a huge amount on there yet (13 shows at time of writing), but Blackpills promises to add a new original series every week and a new episode every day. Impressively, it’s also completely free.

There are some missing features: you can’t download content to watch offline, and – by design – it’s only accessible on a phone or tablet, but overall it’s well worth investigating if you’re out of things to watch or like the idea of shorter, snackable content.

Sunburn is avoidable, and yet it happens to so many of us so often, either through carelessness or just not having a clear enough idea of whether we need sunscreen.

UVLens aims to help with that by telling you the UV index currently and throughout the rest of the day, as well as what that means for you.

Using the current conditions combined with information you’ve given it, such as your skin color and gender, the app will tell you how quickly you’re likely to burn and what you should be doing about it – whether putting on sunscreen or just wearing sunglasses.

You can also tell it the type of sunscreen you’ve put on, along with the activity you’re going to do, and UVLens will then tell you how soon you’ll need to reapply, and send you a notification when it’s almost time to do so.

Basically, using this app means the next time you get burned you’ve only got yourself to blame.

If you’re using a phone with 16GB of space or less then you’ll probably be an expert at making the most of your storage, but even with 32GB or 64GB it’s easy to eat it all up.

ES Disk Analyzer makes it just easy to claw space back, by identifying apps and other data that you might not need, and getting rid of it.

The app’s simplest space-saving feature is its ability to find and delete duplicate files. You might not think you have many of them, but the first time we ran it hundreds were found.

ES Disk Analyzer can also compress images so they use less data, as well as highlighting specific images you might want to compress, (because they’re particularly big or haven’t been viewed in a long time).

Many apps on your phone will also be creating a cache of files which help them load faster. For example, an app might save images to your device so it won’t have to redownload them every time it opens. ES Disk Analyzer will tell you the cache sizes of your apps and let you delete these too if you’re not bothered about such functionality.

And it will highlight particularly large files, in case any of them are expendable, as well as any apps you rarely or never use.

You can also do a deep dive into the file system and see all the files and folders ordered by size, with the option to delete any you don’t want.

Many of these tools can be found elsewhere, either in a dedicated file explorer or in Android itself, but ES Disk Analyzer puts them all in one place.

As its focus is purely on saving you space everything is presented with that in mind, so you can see at a glance where your storage space is going and do something about it.

GIFs are great, but GIFs with your own voice over the top can be even better - or at least that’s the thinking behind Shabaam.

This free app lets you search or browse through millions of GIFs, then add a short audio recording to one. It uses your phone’s microphone, so you can record the sound of anything around you (but can’t use songs or sound files that are already stored on your phone annoyingly).

Once you’re done you can save it or share, with most social media apps supported for sharing, though in some cases it’s sent as a video rather than a looping GIF.

The audio that you add can only be as long as the GIF itself, for obvious reasons, and with that in mind there’s an ‘Editor’s Pick’ section, which contains a selection of GIFs that the developer thinks are ripe for customization, in many cases because they’re longer.

And if you don’t find anything suitable there, you can also use the ‘Categories’ tab and then filter down. For example, you could select the ‘Nature’ category, then from there select ‘ocean’ to get watery GIFs.

Shabaam is still in beta at the time of writing, so it may not work perfectly, but when it does it’s a lot of fun.

If you want a free, easy to use document scanner which also lets you edit the resulting scan you’ll struggle to beat Adobe Scan.

Scanning is simple, just line up a document under your phone’s camera and the app will highlight the sections it’s going to scan. Once you’ve positioned it so that the whole document (or all the relevant sections) are highlighted, just hold your phone steady for a few seconds and Adobe Scan will do the rest.

Then you’ll have a readable scan, but you can also crop it, rotate it, add additional scans to the file, change the color (for example to ‘Grayscale’ or ‘Whiteboard’), rename it, and then save it as a PDF to Adobe Document Cloud. And once it’s in PDF form you can edit it more substantially - adding, removing, copying or re-ordering text for example.

All your saved scans remain accessible from Adobe Scan (and from any device, since they’re saved to the cloud), but you can also email the file, or share a link or the file itself in a message or on social media, or open it in Adobe Acrobat.

As Acrobat is also an Adobe app and your scans are saved to the cloud, you won’t be surprised to find that everything you’ve scanned into Adobe Scan is also accessible from here, which is especially handy given that Adobe Acrobat is one of the main PDF readers, so however you’ve scanned your document it’s likely that you’ll want to open it in here, using Adobe Scan just makes that a little bit easier.

We all know drinking water is important, but it can be easy to forget to do, especially when you’re busy with other things.

Tech has come to the rescue though, with various apps designed to give you a gentle prod to drink more, and Hydro Coach is a strong option.

You start by entering some basic details like your age, gender and weight, and from this Hydro Coach calculates how much you should be drinking.

You can log your intake with ease, telling the app the size of containers you tend to drink from and then just tapping the relevant one every time you’ve finished a drink, and the app will remind you to drink if you haven’t done so in a while.

You can see at a glance both how much you have drunk today and how much you should drink over the remainder of the day and you can also see weekly and monthly statistics.

You can pick whether to measure your intake in millilitres or fluid ounces, while a Pro version of the app gets rid of adverts and adds more detailed statistics for $4.49/£2.49. But for free, Hydro Coach offers a fast, simple way to monitor your fluid intake, and – more importantly – to actually remind you to drink more.

Apex Launcher isn’t new. In fact it’s been around for a long time, and was once one of the best launchers available. Then the developers stopped supporting it, but they’ve just given the app a big update and a new lease of life.

The changes are largely focused on bringing the look in line with modern versions of Android, as well as generally polishing the app and getting rid of bugs, but the core app remains much as it always was: namely, one of the most powerful and customizable interfaces available for Android.

It will replace whatever UI you have now – be that stock Android or a manufacturer’s skin – and give you far more control than you likely had before.

You can change the home page transition effects, make your dock scrollable, hide elements of the interface, such as the dock or status bar, choose custom icons for folders, choose between various different app drawer styles, hide apps from the drawer, set up customizable gestures and a whole lot more.

In short, if there’s any part of the look or feel of Android that you’re not entirely happy with, there’s a good chance you can change it with Apex Launcher. And almost all the features are completely free, though you can unlock some extras with Apex Launcher Pro for $3.99/£3.09.

There’s a long-standing tradition of adding beautiful text to beautiful images. Whether for a poster, presentation, advert or whatever else, text is often overlaid on an image, and for the most part Times New Roman just doesn’t cut it.

With Font Studio you can choose from over 120 interesting, unusual and generally eye-catching fonts, with more being added all the time. Then, you can change the size, color, orientation and transparency of the font, add shadows and put the result on top of an image.

If you want your text to stand out even more you can also add dozens of shapes, for example putting the text in a circle. These too can be tweaked to your liking, or if you’re lacking inspiration you can start with a pre-created template, combining a font, shapes and even sample text and images.

You can also add any of hundreds of stickers to your creations, and blend or combine images. Overall, Font Studio contains a powerful set of typography tools and it’s all completely free.

That said, while your creations might be beautiful the app itself isn’t. Rather, it’s infested with ads. We’d happily pay a small fee to get rid of them, but sadly that’s not an option.

Face swap apps are nothing new, but Microsoft’s Face Swap goes further than most, because as well as the basics of being able to swap your face with a friend’s or something else in your environment, Face Swap also aims to show you what you’d look like with different hairstyles and in different outfits by swapping your face with appropriate pictures it’s found from the net.

The app automatically finds and swaps faces in images and does a decent job of convincingly swapping your face, by attempting to match head tilt, skin tone and lighting.

And if you don’t like any of the categories it gives you or want to use any of the pictures in your gallery, a built-in image browser lets you search the internet for the right photo.

Ultimately, despite all its photo categories, Face Swap is still more just for fun than genuinely useful, but it’s faster and slicker than most of the competition.

We all spend a lot of time web browsing, so we want it to be as fast and simple as possible, and Firefox Focus achieves that, as well as keeping your data private and secure.

The app, which started life on iOS, gives you a stripped back browser with no add-ons and no tabs, but it loads pages quickly and takes up just 3.5MB of space on your device.

More importantly, it also automatically deletes your history whenever you close it, essentially acting like the private or incognito modes in other browsers, but automatically and at all times. And it goes further, by - for example - not appearing in your list of recent apps.

Firefox Focus lets you block ad trackers, analytic trackers, social trackers and other types of content trackers, as well as web fonts – though any of these can be toggled on or off, if you’d rather not block them.

You can also choose what search engine you want to use and set Firefox Focus as your default browser, so links will automatically open in it.

And that’s it. In use it boils down to a settings screen with a handful of toggles and then a main browser page. Simple. Probably too simple for some users, but if you have a low-power handset, one with little storage space, or just value your privacy, Firefox Focus has most browsers beat.

Take a close look at what you’re spending each day and you might be surprised by what you find: those coffees can really add up, and your Kindle addiction might be out of control.

A few small changes could save you a lot, and that’s one of the goals of a finance tracker like Fortune City, which lets you track and categorize your income and outgoings with just a few taps.

It builds up charts and graphs over time so you can see exactly where your money goes and how much you’re spending.

But unlike most finance trackers, Fortune City turns it into a rather cute city management game, erecting new buildings each time you enter an expense or outgoing, rewarding you with achievements for good spending or tracking habits, and even letting you compete with friends to make the best township.

It’s a simple game, but with enough room for progression to keep your interest, and it makes the whole act of money tracking a lot more fun. If you need an incentive to better manage your finances (beyond the cash it could save you), Fortune City might do the trick.

People tend to show their lives in a positive light on social media, with posts about holidays and nights out but few of the moments in between or the feelings underneath.

Lyf is different, as users post their ‘journeys’ through more serious issues, such as illness, anxiety or depression. You can follow and support other users in their journeys by commenting on or reacting to their posts, or start your own journey in the app and build up a positive group around you.

And while much of Lyf is focused on serious issues, you can also create a journey chronicling your photography, world travels, sports, projects and more.

Each journey from each user is about a specific issue or pursuit, but you can create as many journeys as you want and either share them with the world or make them private, thereby only letting those that you choose follow them.

Cooking a meal is only half the battle. First, you’ve got to actually find recipes for things you’d want to eat, which can be complicated by various dietary requirements.

Mealime aims to simplify the whole process, by having you select from various menu types, be it vegetarian, paleo, low carb, flexitarian, pescetarian or no holds barred, then highlight any allergies or restrictions, and finally any ingredients you dislike.

Choose whether you want a meal to contain two or four servings and you’ll instantly be presented with a menu, consisting of four meals that fit your preferences. Ingredients for them will automatically be added to a built-in grocery list, making the shopping simple, and then all that’s left is to cook.

Of course, Mealime helps with that part too, taking on a more standard recipe app role, with step by step instructions for each dish, and clever features like keeping the screen on while you’re in a recipe and moving on to the next instruction when you hover your hand over the display, so you never need to touch it.

Each week you’ll be presented with a new meal plan, so you won’t be stuck eating the same things all the time – though you can save your favorites – and you can change your preferences and requirements at any time.

Mealime is mostly free, but if you want to view nutritional information, get a wider selection of recipes and add notes to recipes you’ll need to sign up for Mealime Pro at a cost of $5.99/£6.49 per month or $49.99/£51.99 per year. Personally, we’d stick with the free version.

Timbre’s full name is ‘Timbre: Cut, Join, Convert mp3’, and that tells you almost everything you need to know about it: this is an app for cutting, joining and converting files.

But the MP3 bit in the name rather undersells it, because Timbre can also work its magic on WAV, FLAC, M4A, AAC, PCM, AIFF, Ogg, WMA, ALAC, MP4, AVI, FLV, MOV, WebM, MKV and MPEG files.

You can convert from one file type to another, which is handy if, for example, your music or video player doesn’t like a specific file type.

You can also trim down audio and video files, or combine several files into one, which you might want to do if you’re editing together a video with multiple scenes, or making a mixtape.

Those are the headline features of Timbre, but there are also tools to remove audio from a video file, split a single audio file into two parts, and change the bitrate of an audio file.

All of these things are simple to do, with Timbre sporting a clear interface, and it’s completely free as well.

Want to inject some personality into your inbox? Astro is here to do just that, combining a slick interface with an AI chatbot.

The AI (called Astrobot) is never more than a tap away, and if you ever get stuck or can’t find a feature you can just type it into the chat box and get assistance.

As well as telling you what and how you can do things with the app, Astrobot can also suggest things you might want to unsubscribe from or archive, or people you might want to make a ‘VIP’ (and thus have their emails appear at the top of your inbox).

Ultimately, Astrobot is nowhere near as powerful as Google Assistant, Alexa or Siri. Ask it a question unrelated to email and you probably won’t get much of an answer, but as dedicated email assistants go it’s pretty good, and doesn’t have much competition.

Elsewhere, the Astro app is less remarkable, but still very solid. Emails that its judges to be important will hit your Priority inbox, and it gets better at this over time, learning, for example, to prioritize emails from people you communicate with a lot.

It’s also full of handy features, like the ability to schedule emails, set up customizable gesture controls, get notified when an email is opened, and sent reminders when you haven’t replied to important emails.

The biggest limitation right now is that Astro only works with Gmail and Office 365 accounts, but support for others is supposedly coming soon.

Your phone’s wallpaper might well be the image you look at more than any other, as well as being the thing everyone sees any time you pull your phone out, so it’s important to choose something striking.

That means not just choosing one you like, but one which matches the overall aesthetic of your handset, and Wallrox Wallpapers makes that easy, as it’s focussed on offering wallpapers that dovetail with the base look of Android, Material Design.

They’re all original wallpapers, so you won’t find them anywhere else, and there are hundreds to choose from - split into a variety of categories - so you can easily filter them based on what you’re interested in.

They’re also all in QHD or higher resolution, so they should look good even on the biggest, sharpest smartphone screens.

And best of all: they’re completely free!

Like sports? Like music? Then there’s a good chance you’ll like Red Bull TV. The app contains live and on-demand shows, films and documentaries of various lengths, packed full of extreme sports action, as well as live broadcasts of music festivals from around the globe.

A built-in calendar tells you when all the events are coming up, so you won’t miss them live, but there’s also a huge selection of content readily available at all times.

And the quality is generally very high. You get full length events, usually paired with professional commentary, while the documentaries tend be well made and give you a closer look at the sports and culture. The shorter shows are sometimes more throwaway, but still a good time killer.

You can stream content to your phone or tablet, and if you’re lacking data or signal you can choose to drop the quality of the stream.

There’s also Chromecast support, so you can watch Red Bull TV on a big screen too, and if you don’t fancy sports or music there’s also a selection of shows dedicated to other parts of popular culture, such as gaming.

Lenka is a simple and free camera app, designed for taking stylish black and white photos. Contrast and color temperature can be adjusted using a pair of sliders, you can tap to focus or have the app choose the focus point, and handily you can use the volume buttons to take a picture, rather than having to tap the screen.

Lenka doesn’t let you use a flash, but interestingly you can optionally illuminate your subjects with constant light from the LED flash bulb.

There’s not much else to it – we did say this was a simple app – but whether you fiddle with the settings or not Lenka can take quite striking black and white shots, and there’s a basic built-in editor, letting you crop and rotate your photos.

If your kids would rather stare at screens than play outside, then Outdoor Family Fun with Plum could be the answer.

Created by PBS Kids, this app provides daily ‘missions’ that can form the basis of family walks and days out, while teaching your kids about nature and science.

There are over 150 missions, with a handful of different ones provided each day, examples of which include taking selfies with insects or noting the different types of weather you come across.

The app tracks your progress and hands out achievement badges, and it’s all wrapped up in a colorful, cartoonish interface that young kids are sure to love.

There are dozens of recipe apps, but few that are both as health focused and deliver the recipes as well as Runtasty.

Coming from the makers of Runtastic it’s no surprise that this has a healthy slant, with all the recipes approved by dietitians and fit for various requirements, whether low-carb, high in protein, low calorie, gluten free, or any number of other things.

Each recipe has icons by its name, indicating its nutritional contents, but you can also filter by a variety of requirements, such as those above, along with preparation time and difficulty.

And once you’re in a recipe you can see its nutritional and dietary information in detail, but you can also see both step-by-step written instructions and a video guide for each and every recipe, which is a combination you won’t find in all apps.

With the ability to create a list of favorites too, and view ‘how-to’ videos for everything from cutting an avocado to preparing the perfect steak, there’s a lot to like here, and while the actual recipe selection can feel a bit sparse it’s a recent app, so we expect more will be added over time.

Finding the best flight search app can sometimes seem as tricky as finding the flights themselves, but Momondo is certainly up there.

Once you’ve picked the relevant airports and dates you can add all sorts of filters, such as how many stops there are, the duration of the flight, the time the flight departs or lands, the ticket class and the airlines.

Customize as much or as little of that as you want, then Momondo will show you all the relevant flights, with the cheapest, quickest, and ‘best’ (which seems to be the best balance of speed and cost) highlighted.

If you’re flexible with dates you can also see a graph showing the prices of flights on each day, so you can home in on the cheapest days at a glance.

And there’s also a section for booking hotels, with its own assortment of filters – including amenities, official star rating, guest rating, price and the type of accommodation it is, so you can book your whole trip from a single app.

Ever find yourself wondering how you’ve used so much data? Or just wondering how much data your individual apps really use? For answers to those questions - and more - there’s GlassWire, an app which tracks all of your phone’s data use, over both Wi-Fi and mobile networks.

It can tell you how much you’ve used in total over various periods of time, as well as how much individual apps are using, and apps are listed by how much they’ve used, so you can see at a glance which ones are using a lot.

You can also view graphs to pinpoint the peaks and troughs of your data use, and set alerts so you’ll know when you’ve used a certain amount or are nearing your monthly limit.

All that and GlassWire is a beautifully designed app too, while costing absolutely nothing.

Almost unavoidably there will be times when you have to hand your phone to someone else, be it to show them some pictures or let them make a call, but what you probably don’t want is the risk of them rummaging through your other apps.

Or, equally, you might not be in the habit of handing out your phone, and not really want to have to unlock it every time you use it either, but still want security for your most sensitive apps.

Either way, Norton App Lock can help, by, well, locking the apps of your choice, behind a PIN, pattern or fingerprint scan.

The app itself is easy to use – just set up the security options you want, then tap the padlock next to any app you want to lock. Once done, you’ll get Norton’s lock screen whenever you (or anyone else) tries to launch the app.

While Norton App Lock isn’t the only option for this it is the best we’ve come across, as it’s fast, loading the instant you tap on a secured app, rather than keeping you waiting. It’s also smart enough not to re-lock an app until you turn the screen off, and it has other handy features too, like one-tap locking of all the apps it thinks you should be securing.

There are all sorts of apps to help you find your phone once it’s lost or stolen, but Pocket Sense aims to thwart a thief’s attempts to steal it in the first place.

The app will sound an alarm any time your phone is taken out of your pocket, so you can catch a thief red-handed.

Similarly, you can set it to sound an alarm if your phone is unplugged from its charger or moved from where you’ve set it down.

The alarm will be cancelled once your phone is unlocked, and you can set a several second delay before it goes off, giving you time to unlock your phone first and thereby avoid alarms every time you grab your phone from your pocket.

But anyone who can’t unlock your phone will be stuck with a siren blaring, even if the phone’s set to silent, so they’re sure to put it down again in a hurry.

Google Earth is nothing new, but it’s been quietly improving over the years and if you haven’t used it in a while it’s well worth revisiting.

Not only can you see the world in full 3D, and even get in for a closer look with Street View, but the Voyager feature lets you get up close and personal with places you might never get a chance to otherwise.

You can explore coral reefs beneath the surface of the ocean, take a trip to the Grand Canyon, wander around museums and more, all without leaving your sofa, using a mix of Street View, information cards, high-quality photos and videos.

Whether you want to be an armchair tourist, plan an actual trip or just learn and be inspired, Google Earth will do the job.

The way news is delivered is starting to feel quite old-fashioned. Sure, we have 24-hour news channels, but we still can’t really pick what we want to hear about and when.

Haystack TV aims to solve that problem by letting you build up a profile with your favorite news sources and topics, and then presenting you with a feed of videos relevant to them, a bit like Flipboard but for video.

It has dozens of news sources, as well as sources focused on video games, tech and entertainment, and you can see all the stories it’s lined up for you at a glance, swiping to remove any you’re not interested in, before hitting play for a completely customized news video.

And you’re not limited to watching this on your phone or tablet, as Haystack TV also has Chromecast support, leaving old school news delivery suddenly feeling even more dated.

New content is added to Netflix every single day, but usually – unless it’s a Netflix original – the service doesn’t do a great job of highlighting it, so you might have no idea a film you’ve been eagerly anticipating has made it to the service.

Perhaps even worse, Netflix makes no real attempt to highlight the films and shows that will be leaving the service soon, leaving you with no idea that you’ve only got several days left to finish binging that sitcom or finally watch that documentary.

But with Upflix you’ll always be in the know. The app provides you with two constantly updated lists – one showing you what’s new, and the other showing you what won’t be around much longer.

You can tell the app your Netflix region (so wherever you are in the world it will have accurate information), you can get push notifications for updates, and each entry is accompanied by the date that it was added or that it will be leaving.

On top of that, you can also view trailers and information on titles, and see their IMDB and Rotten Tomatoes scores. There are also links to take you straight to their page on Netflix or IMDB, and there are some basic search tools to find titles, genres or scores if you’re looking for something more specific.

You might think that working solidly for hours on end is the best way to be productive, but many people find that actually taking short regular breaks is better. It’s such a popular idea that an entire technique has been built around it, called the Pomodoro Technique, and it’s this that’s at the heart of Tide.

The idea is simple: work for 25 minutes then get a 5-minute break. After 4 work periods you get a longer, 15-minute break.

It’s a technique that you might find works, and is definitely worth trying if you ever struggle to focus, as breaking the day into smaller chunks can make it feel more manageable, and you’ll probably find that you resist opening up Facebook while working when you know you’ll be given a break shortly.

You could just use a normal timer for all this, but Tide automates the process, alerting you after each work or break period has finished, but also giving you some control, allowing you to adjust the work and break durations, or change how many work periods you need before a longer break.

When an alarm goes off you have to tap to start the next work or break period, which is more useful than it sounds, as, for example, you might not be ready to go on break after exactly 25 minutes.

Tide also has a beautifully designed interface and optionally plays relaxing nature sounds while you work. We can live without that part, but if, like us, you’d rather work in silence than to the sounds of rolling waves, you can easily turn it off.

Applying for jobs used to involve filling out lengthy arcane applications only to never hear back and wonder: should that time might have been better spent learning Japanese or solving world hunger?

With LinkedIn Job Search there’s still no guarantee that you’ll hear back from your dream job, but it takes out much of the hassle of applying at least, as many of the jobs on this app let you apply using your LinkedIn profile information, so you can apply in several taps, rather than filling out several pages.

That’s great, but it’s not new – LinkedIn itself has been offering that for a while. What the LinkedIn Job Search app does is get rid of all the LinkedIn fluff, like connections and groups, and leave you with just a simple yet powerful job search tool.

You can search by title or keyword, pick a location, as well as how far from that location you’re prepared to travel, choose how recent the job listings have to be and even search just specific companies if you want.

You can fill out as many or as few of these requirements as you want, then filter the results by either how recent they are or how relevant, and before you even tap on a listing you’ll be able to see whether it lets you apply through LinkedIn or not.

If you’re not ready to apply right now you can save it for later, and you can opt to get alerts on your phone if a saved job is about to expire, or if someone has looked at your application – so while there’s no guarantee you’ll get the job, you’ll at least know your application has been seen.

Android only offers 15 different volume levels as standard, which is generally fine, but can lead to situations where you can’t quite get the exact volume you want.

Precise Volume, as the name suggests, gives you more control, with 100 different volume levels built in. As a free app, that would already be just about enough to recommend it but Precise Volume is also packed full of handy tools and features, like custom volume presets and the ability to set a volume limit when using headphones, to protect your hearing.

Upgrade to pro for a one-off charge of $2.49/£2.49 and you get access to 1,000,000 different volume levels, plus the ability to have the volume automatically change based on the app, Bluetooth device or headphones you’re using.

Those features are useful, but not essential, and even the free app will power up your volume controls in ways that you might find surprisingly significant once you get used to having more fine-grained control.

Privacy seems increasingly hard to come by in the digital age, and our smartphones are partly to blame for that, as we text, browse and even work from them in public.

Inevitably, at some point, someone’s going to look over your shoulder, so you’d better hope you’re not working on something confidential or sending sexy messages to your significant other when it happens.

But there are things you can do to minimize the chance of them seeing something they shouldn’t, and one of those things is to use ScreenGuard Lite.

This app will add a pattern or color filter to your screen which makes it a lot harder to make out text and images from a distance.

The strength and color of the filter can be changed and you can choose only to cover a portion of the screen if you’d prefer. You can also quickly and easily enable or disable the filter and change the settings using toggles on the notifications shade, so it’s not too much of a hassle to set up and use.

There’s a separate pro version (not available as an IAP) which adds additional pattern options and lets you set up multiple profiles for $1.58/£1.26, but unless you’re a secret agent the free version should do just fine.

If you’re happy to spend money on a podcast player we’d tend to recommend Pocket Casts, but if you want a decent player that won’t cost you a dime Podcast Go is a great option.

Some podcast players are unintuitive or ugly, but Podcast Go is neither. While it’s not exactly feature-packed, it has all the key tools you’re likely to want.

Searching for and discovering podcasts is easy for a start, with over 300,000 available on the app, sorted into categories (such as entertainment or technology) which you can filter based on what’s popular or trending.

There are also tabs to view any new or unfinished episodes of podcasts you’re subscribed to, making it easy to keep on top of them.

You can also optionally get alerts for new episodes, set new episodes to automatically download, build a playlist, and set podcasts to stop playing after a certain amount of time – ideal if, for example, you like to fall asleep to the soothing voice of your favorite podcaster.

You would think that getting a timer right would be easy, yet so many limit you to a single timer at once. We don’t know about you, but our exciting, fast-paced lives often require multiple timers, as we juggle cooking times, laundry and workouts among other thrilling activities.

Multi Timer StopWatch allows for that, and it’s packed full of other features too. Multiple timers can be saved and customized with their own names and durations, which is handy if you use the same timer a lot.

Each timer can also be given its own sound and you can even set up TimerCeption (timers within timers), meaning the app will alert you after a certain amount of time has passed prior to the end of the timer.

There are widgets too, for easy access to the timers, and there’s a built-in stopwatch. Plus, you can turn off a timer just by waving your hand over the screen.

The app isn’t the prettiest we’ve ever seen, and if you want to get rid of adverts you’ll need to pay a one-time $2.99/£2.79 fee, but for free you get one of the most functional and feature-packed timers around. 

Whisper is one of many apps that let you broadcast your thoughts and feelings to the world. But it lets you do so completely anonymously, with a username that you can change as often as you want and a profile that – at most – contains your age range, gender and approximate location.

The bulk of the app involves short messages, accompanied by an image (usually one suggested by the app and often more decorative than relevant, though you can upload your own). You can then scroll through these messages, sorting them either by those posted nearby, those in groups you belong to, the latest ones, or the most popular ones.

You can reply to the messages if you wish, or start a private conversation with the author. The app as a whole often feels like a more anonymous and visual version of Twitter, albeit without the big brands and famous faces, and with a lot more venting and secret sharing thanks to the anonymity.

But with its focus on people nearby it can also feel more social – encouraging people to talk and even meet.

That aspect is somewhat at odds with the intended anonymity, but you never have to share more than you want to. If you’d rather be a ghost, posting and replying while never revealing a thing, that’s easily achieved.

Seeing that your current download speed is 18.2Mbps is all well and good, but what does that mean for real world use? That’s a question that most speed test services fail to answer, but not Meteor.

This app not only tests your upload speed, download speed and ping, but also assigns each one a rating, ranging from ‘poor’ to ‘awesome’, so you have a better idea of what it means.

But Meteor goes further than that, by assigning the same rating to a selection of apps, so if for example it gives Google Maps a ‘very good’ rating, that means you can expect smooth and speedy mapping with your current data speeds.

And you can go further still, tapping on an app to get a breakdown of what performance is likely to be for different activities. In Spotify, for example, you can view separate ratings for listening to a song or downloading an album in normal, high or extreme quality.

Meteor isn’t perfect: the selection of apps that it can rate the performance of is currently limited to (deep breath): YouTube, Spotify, Facebook, Waze, Google Maps, Skype, Amazon, Dropbox, Chrome, Flipboard, Gmail, Instagram, Google Street View, Twitter, Uber and WhatsApp.

What’s worse is you can only choose six of them at once. But it does far more than most speed test apps to help explain what you’re looking at on your phone and your current data speeds, and it’s got a stylish design and easy to navigate layout too.

Basic fitness trackers don’t cost much, but if you already have an Android phone you can get much of the same functionality with just an app, and Pacer Pedometer is among the best of the bunch.

The app is primarily a pedometer, and one which works quite accurately – or rather, if the initial readings aren’t accurate you can adjust the sensitivity until they are.

Like a dedicated fitness tracker it runs permanently, quietly counting your steps, distance travelled and active minutes as you work towards a target of your own creation.

And there are several different modes you can put it in, depending on whether you favor accuracy or conserving battery life more. This is arguably one area where a dedicated tracker has an advantage, as the heavy lifting is done by a device other than your phone, but if you have it permanently paired to your phone and syncing with an app, the drain won’t necessarily be much less than Pacer’s.

As well as daily step targets, Pacer also lets you work towards specific weight or BMI goals, and if you shell out on a $3.99/£3.99 monthly subscription you can get extra tools to help with that, such as an AI coach and access to groups, but the basic option is still impressively full-featured.

We all need to-do lists from time to time, and while any number of note taking apps can do the job, they’re often a bit fiddly or basic.

That’s why, even if you never use it for more than your weekly shopping, a dedicated to-do list app is worth having.

Of these, Wunderlist is among the best. Beyond the attractive interface there are lots of little things that make it a firm favorite, such as the fact that once you tick something off it disappears, rather than your list simply getting clogged up with ticked items.

But by contrast, the ease with which you can view and restore previously checked off items when you need to do/buy/make/eat them again is a treat.

Wunderlist also lets you set reminders for deadlines, sort your lists alphabetically, put them into folders and sub lists to keep everything organized, and gives you access to your lists from the cloud on your phone, computer or tablet (perfect so you don’t lose your lists when you drop your phone in the bath).

For most users, that’s probably plenty, but Wunderlist goes even further, allowing you to easily share your lists with colleagues and friends, so you can build lists together or split the work. If needed, you can even attach photos and other files to your lists.

But the best thing about Wunderlist is that all these extra features stay tucked away, leaving you with a clean, clutter-free interface that makes it easy to create and complete lists - which is really the most important thing.

TED isn’t a new app, but it is an enduring and regularly updated favorite. Home to over 2,000 TED Talk videos and episodes of the TED Radio Hour podcast, it has interesting content from inspiring speakers on numerous different subjects, with talks covering everything from “the emotional impact of architecture” to “what a driverless world could look like.”

The talks are usually short – taking no more than 18 minutes, so you can fit one into a coffee break, and they can be streamed, downloaded or sent to a TV via Chromecast, depending on how you like to consume them.

Alternatively they can just be favorited to watch/listen to later, so whether you’re out and about or sat in your living room they’re always accessible.

The whole app is simply laid out with a polished look and lots of images, along with tools to help you find new talks. You can check out one of the curated playlists, search by suggested themes, or just type a term of your own into the search box.

And did we mention all of this is completely free? If only school had been this interesting, we might know as much about science and history as we do about phones.

Your phone probably came with a calculator app, but we can almost guarantee that All-in-One Calculator is better. Not only does it have a basic calculator (which changes to a scientific one when you hold your phone in landscape orientation or swipe in from the right edge), it also has over 50 specialist calculators and unit converters.

These cover everything from solving equations, to converting weights and lengths, to working out percentages, averages, density and more. There’s even a currency converter, which updates to offer the current exchange rates, and a BMI calculator.

Most of these you’ll probably never need to use, but next time you need to calculate or convert anything All-in-One Calculator will ensure the answer is never more than a few taps away.

Photomath, as the name suggests, can do maths from images. Just point your camera at a written out problem (which can be typed or hand-written) and the app will provide you with a solution.

It also has a built-in calculator, so you can type problems into the app if you’d prefer, and whatever method you choose you’ll be given a step-by-step guide to reaching the same conclusion as Photomath, so if you have no idea why X equals 4, the app will teach you.

That takes it beyond just being a clever calculator, and actually makes Photomath a great educational tool as well. The core features are all free, but there’s a $0.99/89p monthly subscription to unlock more in depth explanations and learning tools.

Planning trips can be a messy business, with information and bookings often strewn across multiple websites and services, but Google Trips aims to put everything in one place.

Simply search for a location and the app will provide information on attractions, restaurants and more, which you can save to your trip.

Any bookings you make – be it for flights, accommodation or whatever else – can be added from Gmail, and if you're struggling to fill a day you can make use of pre-constructed day plans, which factor in the average time spent in locations and how long it takes to get between them.

Best of all, everything is available offline, so you won't have to rack up roaming charges every time you check your itinerary. 

Ever wanted to bring all your old Warhammer pieces or children's toys to life? Well with Motion you can, or at least to some kind of stop motion life.

The app couldn't be simpler: you just point your phone at whatever you want to animate, press the big yellow button on the screen, then slightly move anything that you want to show in motion. From that, press the button again and continue like that until you've created your masterpiece.

Once all the footage is in place you can play it back, adjust the frame rate if needed and remove any pictures that you forgot to get your hands out of.

You can always go back and add more frames to a project at any point, so you don't need to set aside a whole afternoon to get an intricate animation done in one go. Once you finally are finished you can save it to your phone and send it to your friends/your kids/anyone else who'll still talk to you after seeing your shonky stop motion.

You might never be the next Picasso, but with Prisma you can make your photos look convincingly like an artistic masterpiece.

The app sports dozens of filters, largely based around specific painters or art styles and with a single tap (and a bit if a wait - plus you need to be online) you can apply any of these to any of your photos.

There's no shortage of photo filter apps but these are a bit more inventive than most and actually look convincingly like the art styles they're imitating.

Once you've applied your filter of choice you can lessen the effect with a swipe if it's veered too far from the source image for your liking, then you can save and share your creations with another few taps.

With Call Recorder – ACR the days of having a pen and paper to hand to write down important information mid-call are over.

The app will record your calls for you, as you can probably guess from the name, and it records both sides of the conversation, so you won't just be listening to the soothing tones of your own voice.

If you regularly find yourself scrambling for a pen you can set it to start recording every call automatically, but if you want to be a bit pickier that's easy to do too, with various filters or the option to just start recording manually.

Add in a range of different recording formats, support for cloud storage and a simple system for playing back recordings, which allows you to pause and jump around to different points in them, and Call Recorder – ACR is a full-featured solution. Just remember to tell people you're recording to stay legal and all that.

Evernote is an excellent app for your Android device that lets you stash and sync all your text notes, voice memos and files on your phone and access them through a desktop computer.

It's a brilliant productivity tool that lets you organise and search your notes so you always have exactly what you need at your fingertips.

The paid premium version unlocks offline access and passcode protection, but for free you still get a vast, feature-packed digitial notebook that's easy to navigate.

Boost your productivity with Pushbullet, which lets you view your Android phone's notifications and messages directly on your desktop PC. It means if you get a text message you can read it there and then without having to take your phone out of your pocket or bag.

You can also quickly send files from your computer to your phone with only a few clicks, and if you regularly find that you email links to yourself just to open them on your smartphone, then you'll never have to do that again thanks to Pushbullet's link sharing features.

There are probably hundreds of photo apps around, but Google Photos stands out as it gives you unlimited storage for photos and videos, all for free.

That's reason enough to jump on board, especially as it works not just on Android but on iOS and computers too.

But with basic editing tools and the ability to make collages and albums this is more than just photo and video storage, it aims to be your first and last stop after taking a picture. To achieve that it will need a few more features, but it's well on its way.

If you're serious about running or cycling then you should be serious about Strava. As smartphone fitness tools go it's one of the best, allowing you to track your performance, set goals and see daily progress updates.

There are leaderboards and challenges to give it a competitive edge and if you're ever not sure where to run or cycle you can find user created routes on the app, or share your own. All of that comes free of charge, while a premium version adds even more tools.

Even in 2015 there are still times and places where we can't get an internet connection, but this doesn't have to mean you can't read websites, however, thanks to the excellent Pocket app. It allows you to save articles, news stories, blog posts, videos and much more, letting you read and watch them offline.

You can also synchronise your saved articles across every device you've installed Pocket on, allowing you to pick up where you left off and continue reading. With unlimited storage you can build up a whole library of content and the app even makes recommendations of new things it thinks you might like.

Arriving in a brand new city is always exciting but it can also be a little daunting, especially if you need to get around using public transport. Citymapper - Bus, Tube, Rail is a brilliant app that brings you real-time information on public transport for cities around the world.

You can easily plan your route using all kinds of transport, from buses to ferries, and you can be kept up to date with real-time data, including any disruptions or cancellations. An essential app for any city-bound traveller.

It might not be quite as glamorous as other media players, but if you want a no-nonsense app that can play pretty much any media file under the sun, then VLC for Android is the app for you.

It spent a long time in beta, but it now delivers a stable, full-featured experience, complete with support for subtitles, multi-track audio, DVD ISOs and network streams.

That's all packaged in an easy to use player, with widgets and gesture controls. So you don't need to worry about getting your media to work, you just need to launch VLC and press play. The app will do the rest.

IF was formerly known as IFTTT, which stands for "if this then that" and handily sums up what this app does. It's a simple ethos that gives you a huge amount of options for making your Android device even smarter.

You can create simple statements such as "if any photo is taken then add them to Dropbox", or "if my location is home, send a text message to my partner saying "I'm home!"" which can also be shared with other IF users. You'll be amazed how much you can do with such a simple premise.

One of the best things about Android is how customisable it is, and there are loads of apps out there that can help you change the way Android displays and launches apps to suit your preferences.

Out of these Nova Launcher is arguably the best, giving you complete control over your home screen. You can change the icons, themes, colours and layout, completely hide apps that you don't use, set up gesture controls and add funky affects when navigating your phone.

It might sound bloated but you can use as many or as few of these features as you want, so if you want to keep your Android experience slick and minimalist Nova Launcher can do that too.

Google Fit is an excellent app for keeping track of your activity and you don't need any additional fitness trackers; you can just carry your Android phone around with you. If you do have Android Wear-compatible fitness trackers and wearables, then Google Fit gets even better, as it can gather data from them, displaying it all in one place.

Fitness goals for dailys step counts, calories burned, or time or distance of exercise can also be set to help you reach the level of fitness you desire, as well as keeping you motivated.

If you fancy learning a foreign language then make sure you download Duolingo: Learn Languages Free, as it's one of those rare apps that manages to be both educational and fun, ensuring that you'll keep coming back for more to brush up on your language skills, with bite-sized, genuinely useful lessons and tests.

Spanish, French, German, Portuguese, Italian, Dutch, Irish, Danish, Swedish, and English can all be learned, it's completely free with no ads or hidden fees and it's one of the best ways you can learn a new language with your Android device.

If you want to keep your various accounts and logins secure then it makes sense to have a strong, unique and regularly changed password for each. But unless you have a photographic memory that also means you'll be hitting the password reset button roughly 6000 times a day.

That's not ideal and it's where password managers, such as 1Password, come in. This gives you an online database of all your passwords and automatically fills in login fields, so the only password you need to remember is the one for 1Password itself.

Except now you don't even need to do that, as the app has added fingerprint support for devices running Android Marshmallow.

1Password is securely encrypted, so your logins are safe and it works across Android, iOS, PC and Mac. The core app is free but to unlock all the features you will need to make a one time in-app purchase.

Endomondo - Running & Walking bills itself as the only personal trainer you'll ever need, and it's a pretty darn accurate claim. No matter what sports or fitness activity you perform, this app will track your progress and give you information on speed, distance, calories burnt and more.

You can keep a training diary to view your progress and set workout goals and challenges to help keep you motivated. Plus social features allow you to share and compete with your friends.

While Endomondo works well on its own it can also be linked up to other apps and wearables, so you can get a complete picture of your progress.

This one pioneered the concept of the alternative keyboard, with SwiftKey the first to offer to 'learn' your writing style and attempt to predict your next word. The hope being that, with practice, it'll know what phrases you commonly use and might save you quite a bit of fuss in typing a simple message to a friend.

Rivals have sprung up but SwiftKey is still the king, with accurate predictions and a massive number of customisation options.

You used to have to pay for the app, but now you don't have to spend a penny to give your keyboard a big boost.
