The undulating noise machine provides you with perfect looping samples of white, pink and brown noise used by people looking to sleep and dream; but then it goes two steps beyond.
In the first step beyond it can play back motions in the sound at the same speed as the resting human heart rate (60 bpm) in order to lull you into rest with shaped white noise.
The second step beyond is to give you a shaping machine which allows you to produce those rhythmic motions yourself. There is a drum/metronome option that plays at 60 bpm to help you get the motions at the right pace.
There are online help videos provided that also go into some of the aspects of self hypnosis ready to draw you into a calm state for dreaming.
A 1.0.1 update will be released with a record feature in the next few weeks so that you can enjoy your creations further down the line.
Note, I've just spotted this review and I'll work on it quickly (amazing review dude, if ever you want something done then do it like that):
Needs timer & screen saver **
by Insommiac - Version 1.0.0 - Jun 12, 2013
Im an insomniac. My struggle to sleep is epic some nights. This app is the only sleep machine that i could find with undulating noises that you can control. For that i give this 5 stars! I found the right rhythm and bam i was out like a light, and I was really struggling this night. However, being version 1.0, it ain't perfect. The screen doesn't shut off like most music apps, forcing you to lay it face down and draining the battery. Also there's no sleep timer, so it runs all night draining the battery. The app would properly ruin my iPad if i ran it every night making the app essentially unusable. Once this is fixed... THIS IS A FIVE STAR APP. FIX IT!
