Clap Or Crap

Prepare for the biggest invention since fire: Clap or Crap.
Now you don't have to use your hands to applaud anymore, you can just use your phone, tablet or other device.

Use this app when watching a sports match, music concert, or any other situation where you might want to applaud (clap) or scream 'boo' (crap).
Even when you don't want to applaud or scream boo you can use this app, just hold the thumb in the neutral position.

There are 3 positions:
- Positive: thumb up, crowd cheering
- Neutral: thumb in the middle, crickets chirping
- Negative: thumb down, crowd booing

Move your device to rotate the thumb up or down (or anywhere in between), make sure the sound is turned on.
On devices that don't support rotating (for example the Xbox One) the thumb can be rotated with a slider.

Note: rotate the thumb between neutral and positive or negative to slowly start clapping or booing.

Instead of the thumb you can also use the 'sign of the horns' hand, and you can change the background color.
