DigiDrummer by Magnus Larsson is – in my opinion – the best drum app for the iPhone. DigiDrummer Micro is its little brother. There is also a lite version of this app with only 1 drum set.

Micro has DigiDrummer’s great layout, almost zero latency, the ability to record one track and plpay along to to your iPod music.

It features 8 full drum sets.

Fake Caller is a great app for getting out of a boring meeting, a bad date or an embarassing situation.
Once activated, Fake Caller will make your iPhone (or iPod touch) look like it’s locked and neutral.

Once answered it switches to a fully functional call screen. You can put the call on hold or mute, you can add fictional calls, browse through …

A really simple but fun app from Microlemon.

All you have to do is to hit a white dot on your sceen. After every hit, a new dot appears in a random location. The trick is that if you don’t hit the dot fast enough, it moves to a random location itself. You won’t notice it in the easy level, but in hard mode, it makes the game very difficult.
