Lont-time Droid user, just switched to iPhone 6 last week. My Droid had a very simple, free app that allowed me to silence ALL sounds on my phone (Buzzoff). I could set it for a certain amount of time and it would turn the sound on when that time elapsed (e.g. 90 minutes while watching a movie). Or I could set it for a distance (e.g. 100 yards) and it would remain silent until I moved that defined distance. Another thing I need is the ability to turn off all sounds at night except for my alarm and any phone number I choose (e.g. Silent Time). I manage rentals and need to receive text messages from an emergency line without receiving calls/texts/notifications about anything else. I'm searching the app store and not finding anything.
