It's time for our weekly roundup of the best new Android apps and games to have emerged on the Google Play store.



As ever, prices are correct at the time of writing, but may have changed by the time you read this. (Free + IAP) means in-app purchases are used within the app.

APPS

It's fairly pricey – although a free Demo version is available to try before buying – but Grapholite looks well worth the cost. It's an app for putting diagrams together, for a range of business uses: from Venn diagrams and flow charts to office plans and technical drawings. Everything's exportable, and the app plays nicely with developer Aphalina's existing software on other devices.

This is definitely something to keep an eye on: "the world's first integrated digital healthcare system". What that means is a service – for which this app is the front-end – that helps you book a doctor's appointment, get prescriptions delivered, and be referred or treated as necessary. Wired has more details on the company behind it, and its ambitions.

Already available for Android tablets, PhotoDirector now works on smartphones too. It's a photo-editing app from CyberLink that makes it easy to edit and share photos, ensuring they're just so before slapping them on Facebook, Twitter and other social sites. A single in-app purchase removes ads and boosts the resolution of your saved images.

Snaply is the latest app hoping to help you declutter your house, released in beta for Android. Well, I say "declutter" – it's an app for selling stuff simply, but also for buying it, so you may be cluttering more with your purchases. Even so, it looks handy, tying into existing UK freecycling site Freegle to help you get and get rid of items.

Richard Herring and Sean Hughes are among the comedians available through "the UK's first uncensored national radio network", which now has an official Android app. The app – which includes voting and other features to respond to broadcasters – provides a one-month trial, then you'll be prompted to sign up for a £2.99 monthly subscription.

This business app was warmly received when it came out for iPad last year, so its appearance on Android should widen its audience. It's designed to be used in workplace meetings, from sales conflabs to board meetings. You can see who's attending, take notes for sharing after the event, and keep tabs on the agenda.

This is the latest attempt at a social network for sports fans, with former footballer Michael Owen signed up for promotional purposes. You can connect to other fans, blog about your sporting views and predictions, and customise it to remove any sports you're not keen on.

This mobile shopping app is only available in the US, as it focuses on retailers like Target, Macy's and Nordstrom. It aims to be a handy guide to discounts in local stores, with a feed of the latest sales, and the ability to share details with friends, or construct your own bargains shopping list before heading out to buy.

Sometimes it's the most laser-focused niche apps that can be the most useful. Moving Curtains has the makings of one of those: an app that gets you to take a picture of a window, then test different curtain designs out on it – including the ability to scan fabric to see how they'll really look.

Finally, something from Barclays Bank: an app aimed at 11-19 year-olds trying to polish up their recruitability. It's split into three sections: work skills, people skills and money skills, and ties into an existing program for schools based around getting students into suitable work experience.

Clumsy Ninja for Android.

GAMES

There's great joy to be had in this game from NaturalMotion, which sees "the most hapless ninja ever to grace a touchscreen" trying to train himself up. Trampolining, balloon popping and painful-looking basketball (with the ninja as the ball) are all part of the fun, with the excellent animation giving him real character.

One of the bargains of the Google Play store in terms of entertainment-per-quid, as this classic sci-fi strategy game makes its way to Android. Your job is to fend off an alien invasion with a squad of tooled-up soldiers, with an emphasis on tension and careful tactics rather than simply blundering around shooting anything that moves.

Pac-Man has a long and occasionally ignoble history of spin-off games, as he tries to break out of his maze/pills formula. This latest attempt is essentially Puzzle & Dragons – one of the most lucrative mobile games in the world today – but with Pac-Man and various monsters. But still with pellets. It's a colourful-looking puzzle-RPG with Pokemon-ish monster evolution included.

If it takes 10,000 hours of practice to master a skill, I might just be a master of Defender of the Crown's jousting and catapulting mini-games, from my teenage years. Now the famous Cinemaware game is back for Android: a faithfully-emulated version of the game that sees you conquering England in the Middle Ages.

Itching for a satisfying shoot 'em up for your Android device? Chillingo's Abyss Attack is the latest contender: an eye-frying shooter set underwater, as you steam through a series of neon levels letting fly at creatures and bosses, with power-ups and relics used to tune your submarine. It's very good indeed.

Developer Kobojo has enjoyed some success on Facebook with this RPG, attracting nearly 6m players on the social network. Now it's on Android, as you build a team of mutant monsters to fight against enemies and other players alike. Breeding stronger mutants and refining your strategy should give it plenty of depth.

If you enjoyed Sony's Wipeout back in the day, you may recognise a healthy dose of its DNA in Flashout 2, an antigrav-racing sequel on Android from developer Jujubee. It looks good, moves smoothly, and has a juicy career mode to work through, as well as online multiplayer to play the world.

This is the latest game based on Games Workshop's famous Warhammer 40,000 world, although don't expect a faithful translation from tabletop to mobile. Instead, this is a Plants vs Zombies "lane strategy" game using some characters from the original game, complete with multiplayer running across Android, iOS and PC.

This is great fun: a physics-puzzle game set inside the body of a "strange creature". Your job is to eat white cells, avoid monsters and dive your way down as deep as you can. Simple, squashy and with plenty of just-one-more-go addictiveness.

Finaly: cars and football... together at last! This sounds very strange, but actually works much better than you'd think. It sees you screeching cars around a pitch trying to score goals – and while the Android-controlled opponents offer a challenge, the game comes into its own on a tablet against another human tapping the same screen.
