On the right track

I liked the concept of this app as I was looking to transition to a biphasic sleep pattern. There are a few minor bugs with it, which is expected with any new app. These include playing alarm after turning it off; some menu items do not respond to touching; etc. This was the loss of half a star.
I am also looking for a more customizable program. The guided program has short adjustment periods of 2 weeks and starts you off at 2 3 hour naps. From the research I had done I wanted to start with a 4 week adjustment periods and 6 hours of overnight sleep and one 30 minute nap. However to do this I had to manually set up the sleeping times, which then seems to disable some of the adjustment tracking. So this was the loss of another half a star.
The other 2 stars I took away because of the massive battery hog this app is. Ive lost over 40% battery life over a 6 hour sleep cycle. This is unforgivable when it is the only active app running overnight. Even using airplane mode doesnt seem to help that much with about a 30% drain overnight. This means the phone must be plugged in overnight, which is not recommended for sustaining the lifespan of the battery. If they battery drain issue is fixed in an update, I will adjust this score to 4 stars.
