Best new apps for iOS, Android and Windows

This week's highlights include the arrival of Fallout Shelter on Android, and a crash course in the Game of Thrones novels:

1. My BT

Available on: iOS, Android

Price: Free

Publisher: BT

If BT happens to supply your broadband, mobile or TV services, we can't think of a good reason not to download the operator's latest app.

My BT for iOS and Android lets users manage their account from their mobile device, checking recent bills, reviewing the services they are signed up for, and more.

It comes in really handy when your WiFi is on the blink, since it allows users to reboot their router remotely and book an engineer in-app if that doesn't solve the problem.

2. JustWatch

Available on: Android, iOS

Price: Free

Publisher: JustWatch

Searching for your favourite content on-demand is now easier thanks to JustWatch, a search engine for the world's biggest streaming services (legal ones, of course).

Available in app form for iOS and Android as well as on the web, the service lets users trawl Netflix, BBC iPlayer, Amazon Instant Video, and more in one fell swoop.

It will even help you find the best deals on movie rentals and purchases, and keep track of newly-added content on your favourite streaming platforms.

3. MyHeart Counts

Available on: iOS

Price: Free

Publisher: Stanford University

This app can't be knocked because it has genuinely good intentions - to provide data for researchers studying heart disease.

MyHeart Counts is essentially a fitness tracker that syncs up with Apple's ResearchKit platform to provide Stanford University with your cardiovascular data.

As well as sharing important medical data with researchers, the app will also paint a picture of your own cardiovascular health and inform you if you are at risk of developing heart disease.

4. A Game of Thrones: Get into the Books

Available on: iOS, iOS

Price: Free

Publisher: Harper Collins

There must be hordes of Game of Thrones fans out there who adore the hit television show but have never so much as opened one of the books.

This app from publisher Harper Collins is aimed at anyone who is ready to make the leap from the TV series to the world of George R R Martin's novels, offering them a crash course in A Song of Ice and Fire before they tackle the first book.

Here you'll find extracts from the text and introductions to the literary incarnation of each character. And don't worry, there's a setting to block out spoilers.

5. GIF Wallet

Available on: iOS

Price: Free

Publisher: Grigonis Brothers Software

GIF Wallet provides iPhone users with a handy repository for storing all of their GIFs, so you'll never lose track of where they're hosted online or lose them among the contents of your camera roll.

Sharing options allows users to embed GIFs into iMessages, emails, tweets, Facebook posts, and more, adding levity to any correspondence.

With this app on your side, it's never been easier to keep tabs on your dancing cats.

6. Genius

Available on: Android, iOS

Price: Free

Publisher: Genius Media Group

Genius is aimed at users who have ever found themselves struggling to grasp the meaning behind cryptic song lyrics, poetry, literature or news articles.

The application taps into an extensive database of annotations for all of the above, providing insight into the underlying meaning behind the artist or author's work.

Genius was released for iOS devices early last year, and has just made the jump to Android.

7. myTube!

Available on: Windows Phone

Price: 79p

Publisher: Ryken Studio

Windows Phone users are often reliant on third-party apps for many of the features iOS and Android users take for granted - and now they finally have full YouTube functionality.

myTube! plugs a gaping hole on Windows Phone by allowing users to upload clips to the world's biggest video network from their handset.

It also lets account holders delete videos from their profile, like and dislike clips, and search for content within a channel. If you're a YouTube addict on Windows Phone, it's worth investing 79p in this app.

8. Fallout Shelter

Available on: Android, Android

Price: Free (with in-app purchases)

Publisher: Bethesda Softworks

We usually stick to non-gaming apps in this round-up, but could resist including a plug for the uber-addictive Fallout Shelter now that it's dropped on Android.

Bethesda's debut mobile game casts players as the Overseer of a nuclear bunker in the Fallout universe, protecting its dwellers from the horrors of post-apocalyptic life and tending to their every need.

The strategy genre gets a radioactive makeover in this novel spinoff.

9. Sun Goals

Available on: iOS, Android

Price: Free (with subscription charges)

Publisher: News International

This one makes the cut for the benefit of Sky Sports subscribers, who now have access to goal replays from the Premier League, Champions League, Europa League, FA Cup and Scottish Premiership on their mobile device via the Suns Goals app.

Sky Sports customers can relive every back-of-the-net moment on their iOS or Android device thanks to a partnership between the broadcaster and The Sun newspaper.
