Coming from WinMo I've been using the PPCProfiles app and it has been a God sent to me. What that does is manage the phones volume automatically. You set a template and it switches from silent to normal automatically and vice versa. I used it to switch my phone to silent when I went to sleep and then switch it back to normal volume before my alarm (on the phone) would ring in the morning. It is very useful if you use your phone as an alarm, otherwise obviously you could switch manually before going to sleep and after waking up. So, is there an APP like that for Android?
