We often need to keep our phone on silent mode, i.e. ringer off, this is required 
especially during meetings, movies, or while we are sleeping. The issue we often face with this activity is we forget to turn the ringer on after the meeting, movie or our sleeping hours are over and hence we end up missing some important calls. Here is a free Android app which can help you.
Named as Shush! Ringer Restorer, what this free Android app does is, when you turn off your ringer using the volume button on your device, it asks you the time span for which you want to keep your phone on silent mode, and once this span is over, it will automatically turn the ringer on.
Have a look at this video of Shush! Ringer Restorer –
Installing Shush! Ringer Restorer doesn’t mean that you will always have to put your phone on Silent Mode for some specific time span, you can choose “Keep it off” button to manually activate the ringer whenever you want.
Shush! Ringer Restorer seems to be a nice app, definitely helpful for you if you often forget to turn the ringer of your phone on, go ahead and try it out and share your views about it with us. You can also use RD Mute which too is good way to mute your phone and bring it back to normal mode just by flipping your phone’s down.
