Best one yet – Sleep Bug Pro: White Noise Soundscapes & Music Box Review

I've tried many different sleep machines, mostly free ones on the iTunes Store. This is by far the best one I've tried. The interface is clean. The sound doesn't stop if I go into another app. You can add to the sound if you want (birds, wind, etc.) and there are plenty of sounds to pick from.
