Sleep!
This is a wonderful app, but the latest version shuts itself off after about ten minutes, if I neglect to put my devices to sleep, which wakes me up, of course.
I would also love for the initial screen to be dark, not bright white. The point of using this app is to fall asleep, and a giant white light in my eyes when I start the app wakes me up too much!
Otherwise, its awesome.
