School Bell (No Ads)

Do you want to finish class early? Set the timer or immediately trigger the bell: your teacher and the other students will think that it's the end of class. Or another joke: discreetly install the application on the phone with a friend and set the timer so that it goes off. The sound perfectly imitates a school bell. Ideal for pranks.

• Press the button to start the timer or trigger the buzzer.
