There are 100 FREE copies of an app I developed called FlipOFF available. Here is the description and features:
Allows user to disable alerts, vibrations, and audio by placing phone face down. Allows to individually filter SMS, Email/Pin messages, phone calls, and all other alerts. Allows you to also disable the radio when placing the phone face down (this allows you to disable all alerts and sounds that do not generate from the phone itself - alarm, music player, calendar, etc). Also allows you to disable monitoring by the app when it is not needed. Saves settings across reboots.
