Ive been using Pzizz since 2008. Nothing helps me sleep like this app. Also really good for naps, the separate nap function helps you get a refreshing nap of your specified length, but wake up without as much of the nap tired sleepiness afterward. Great app, and as a beta tester for the new version I can say that the new expanded functionality is going to be amazing!
