I'm looking for a good night time application to auto silence my phone during a schedule, but allow vibrate ring for specific contacts. I keep my phone on vibrate ALL the time & I am looking for an app that will silence the vibrate from 11PM-6AM, but, still vibrate for certain callers. For example, my wife calls me at 3AM, I want the phone to vibrate if she is on the exception list. I have tried several apps, but I can not find anything that works. Any ideas?
