I use it regularly & love it

First: The settings button works perfectly well. You can also just swipe left on the main screen to get to Settings or swipe right for the Menu.

Now, the review: Ive been using Pzizz for about two years, mostly for the power nap module, but occasionally for the sleep module. I cant think of a single time that it didnt successfully put me to sleep. Ive really been enjoying the power naps, which really work for reenergizing me.
