Brain Caffiene

Check out coffitivity , it's an app that plays you some background sound that will help you defocus. Some people have playlists, some people use white-noise generators, and others have... Well a Spotify playlist even.

I can see other kinds of applications for this background noise. OK, so.... Have you ever tried to concentrate in a completely silent room, if like me the circus comes out and your mind runs riot, this app might be just the ticket.
