The Sweet Dreams app is a useful app that conveniently blocks calls during the times when you don’t want to be bothered — without lifting a finger or fixing your phone’s settings. It’s perfect for the playboy or playgirl that wants a full night’s rest without being bothered by the phone. Or, if you’re a student constantly having to switch your phone on silent mode whenever you enter class. Or, if you just plain don’t want to be bothered by anyone trying to call you.

The app works according to different filters you set based on location, movement or sound. At the bare minimum you set your typical sleep times/do-not-disturb times and enable the app. If used regularly you can forget about it as it will automatically work for you in the background.

Sweet Dreams is available for free here.
