Better than real (recordings of) rain
The rain sounds are seamlessly woven together so there are none of the drawbacks of a typical recording. Getting to tweak the exact character of the rain is awesome too. This is my favorite ambient noise generator. I wish I could run the Simply Rain and Simply Noise apps simultaneously like on my laptop though--my favorite is having a steady low brown noise and a prominent oscillating rain with light thunder. Oh well, this still puts me to sleep like a baby.
