Brilliant App!
I just started using it to track my snoring and figure out if I might have sleep apnea. It works amazingly well and shows you all of your snoring episodes for the entire night in a simple chart that you can analyze minute by minute. It barely uses up any battery while it is doing this and you can turn your iPhone to the sleep position and it will still work.
