(Sorry, for Android phones only right now, I'll try to compile it for iPhones eventually)
-This app utilizes white, pink, brown and black noise and it seems to run smoothly and consistently
-I've been using this app to fall and stay asleep to for about 3 months now, and it works great with a bluetooth speaker
-I decided to make this app free for now at least, so grab it before it goes back to a whopping 99 cents!
-Just move the little
icon around the screen to select your noise level and the screen will go (mostly) dark in 60 seconds
