Very, very relaxing.

The app is extremely well done. The ability to dial in the other sounds-birds, wind, water, etc. and adjust the volume for each lets me make this into exactly the experience I want.
There is one shortcoming, however: the app cannot run in the background, therefore the screen cannot be off. This is a huge drain on the battery, so the app is best used while plugged into the charger, which limits the utility of the app. For this reason I have given it a 4, rather than a 5 star rating.
