Ringer mode timer widget (v. 1.01) Разработано OpenSourceTown

Ringer mode timer is a button that you can place on a home screen. When you press this button, it cycles between Ring, Vibrate, Silent, and a timer is set so that the mode automatically changes back (reverts) after a set amount of time. You could turn the ringer off at night and set it to turn back on in the morning.
