With one single click in this app, you can mute your device as well as set it into airplane mode. Vibrations can be on or off as you prefer. You can specify a future time (e.g. 5 minutes before the start of a meeting) when the device must set itself automatically in silent mode or airplane mode. Simultaneously you can specify the time when the device must restore automatically its original state (e.g. 15 minutes after the scheduled end of the meeting). For that purpose you can choose between a duration (e.g. 1 hour after the start of the silent mode) and a moment (e.g. at 11:05).- The silent mode and the airplane mode are always enabled and disabled at the correct time, even when changing the time zone or stopping and restarting the device in the meantime.
