Ive been using this app for a couple of weeks now, and I was surprised by how helpful its been. The mans voice is incredibly soothing, and the on and off narration is made of comments crafted by the sleep gods, I swear—I dont know how they manage to be so useful, yet unobtrusive. Although I originally found the music to be a little too distracting, the app lets you adjust the volumes of both the voice and the music independently, which immediately solved my problem. The only change I would like to see would be a one-tap way of changing modes. Since there are only two modes (nap and sleep), I dont quite understand the need for a third screen intermediary, and often find it a slight annoyance when all I want to do is crash for a little while. But this is relatively minor. The interface isnt the most attractive, but you wont be staring at it for very long (not that its awful either), and this app is overall pretty damn great at helping you calm down and sneak in a snooze.
