RD Mute for Android: Flip over to silence your phone
It’s a simple app that mutes all Voice functions when you flip your phone. It also has a car mode, where it detects the speed at which you’re driving (which can be set by the user), and mutes voice functions above that speed. You can also set it up to send a text message to the caller, or only reply to specific numbers when muted.
Unfortunately the app doesn’t allow you (yet) to reply automatically to incoming calls when you’re not in car mode, but it should come up in the near future (I hope!).
You can download it from the market, here. Or scan the Barcode to the right.
