Just ok

This is similar to inception - the app, which is free. It has different sounds, white noise, etc. that get louder when the mic picks up the ambient noise in the room. It is adjustable which helps a bit but you are better off trying inception - the app before you buy this. Its not bad for $.99, but it should be free or they should have at least had a lite version.
