Humble Bundle for Android Up to you
Get three popular Android games – Osmos, Anomaly and Edge – for however much you feel like paying and Humble Bundle will throw in the excellent World of Goo if you pay more than the average. Plus you can then play the games on your PC or Mac for no cost, and some of the profits go to charity. Win-win-win.
Aviary Photo Editor £Free
Actually a plug-in that you can access when you hit 'share' on your snaps, Aviary Photo Editor is well worth a download. You can crop, flip and rotate photos as well as adjusting brightness, saturation and contrast. There's also teeth whitening and blemish removal – for anyone less good-looking than the Stuff team.

Not the most exciting of apps at first glance but a clever one – RingDimmer automatically adjusts your ringtone to match the noise around you.
