Camera tosses are a well-loved tradition with photographers. You don't need professional gear to stage spontaneous pics of your own—you just need ThrowMeApp, an Android Phone and a little bit of hand-eye coordination.
Takes pictures when you throw your phone in the air. It activates the camera's shutter when your device is at the peak of its climb and the lens is facing downward.
The app uses the phone's accelerometer to sense how fast it's falling and calculate an average fall speed based on your earlier tosses. You don't have to do any decision making when it comes to the actual shutter snapping, either. Just tap the screen, chuck your phone, and hope for the best. This is not an app to be used by klutzes.

The Best:
Calculates fall velocity
The Worst:
Seems to be crashy
