Shhhhhh...Manage Your Ringer with Shush! Ring Restorer
"When installed, the Shush! Ring Restorer app monitors your phone's volume, and when you mute your phone, automatically prompts you to set how long you'd like it to remain silent-so, for example, you don't forget to turn your ring back on and miss important calls."
Shush! Ring Restorer app is easy to use and one heck of a handy app to have! The app turns your ringer back on after a pre-determined amount of time that you set. The app automatically asks you how long you would like for the ringer to remain off when you turn your ringer volume all the way down. Great app to have when you are napping, at work, the opera or your kid's soccer game.
