Sounds = Imagery
I just got this app yesterday, and started mixing some sounds. It was so awesome to just hear calming birds chirping and a stream running that I decided right away that Id use it to fall asleep. I had no idea Id actually like just listening to sounds, but it is so relaxing to. Mixing the sounds in certain ways surprisingly makes it so easy to paint a picture in your head. I used chirping birds, wind, a stream and leaves rustling to make it sound like I am on a mountain, perhaps sitting on a chair by a cabin. It is so easy to see yourself somewhere else when there is sound and you close your eyes, I had no idea. I find it to be the perfect way to take your mind away from everything before you sleep.
The app does keep making sounds even when you exit, meaning you can listen to it while on Facebook, reading, browsing the Internet, etc. (maybe even when writing App Store reviews...) It also has a timer so that you can set how long the sounds play for, meaning you can sleep without caring about battery (the sounds will fade out one by one when the timer ends, which actually makes you feel like you are falling asleep, its crazy). I do agree with some earlier reviews though that you should be able to set these sounds as an alarm, because that would be awesome.
