Let Me Sleep will automatically set your phone in silent or vibrate mode every selected hour and set the volume back to normal at the scheduled hour.
This application can also be used during the day, you can for example put your phone in silent/vibrate mode while you are at work, at school or during a meeting.
You can add more than one period, this is convenient if you want a different period for the weekend.
