This is a very fun Shaver application. It uses the proximity sensor to trigger the vibrator and a real shaver sound.
It sounds and feels real. Simple and efficient. You do not need a ton of useless feature. It has just enough to make you and your friend and family to believe this is a real electric shaver, at least for a few seconds =D
It is also fun with your dog... looks like you are really shearing the dog (or cat) =D
