Developer apps cydia launch release WaveOff, This tweak works with iOS 6 or higher. WaveOff v1.0.2-1 tweak for ability to turn the screen of your iOS Device off and on by simply waving your hand over the proximity sensor. WaveOff harnesses the power of your iPhone’s proximity sensor to do this. When you perform a smooth, slow wave in front of your iPhone reasonably close to the proximity sensor, your screen will turn either on, or off, depending on its state when you perform the gesture.
WaveOff does not unlock your iOS device if it’s locked. All it does is turn the screen on or off. Because of this, the tweak only works when the device is already unlocked, such as when you’re on the home screen or in an application.
