School Bell

You want to finish the class early? Set a timer or immediately call bell: your teacher and the other pupils will think that this is the end of the class. Or another anecdote: discreetly install the app on a friends phone and set the timer so that it went out. Perfectly mimics the sound of the school bell. Perfect for pranks.
