Minyan Silencer

Tired of remembering to silence your phone's ringer during prayers, meetings, or classes? And when you do silence it, do you sometimes forget to turn it back on again afterwards? Then you need Minyan Silencer.

MinyanSilencer lets you set up multiple schedules when your phone should automatically turn off its ringer, and then later turns it back on. Schedules can be configured either in absolute time, or relative to sunrise or sunset (particularly useful for prayers / minyanim). If your phone doesn't have GPS, you can manually select a city for calculating sunrise & sunset times.

An added optional feature (must be turned on in settings) works when you manually silence your phone, and asks you when you would like it to turn back on again.
