Great way to wake up optimally!!

I have used this app for several months and found it to be a great way to wake up at the best time in the sleep cycle resulting in being optimally alert. The Sleep charts are very well done and significantly better than other sleep apps that I have used. I have found it to work well if I close all other apps except for this one when going to sleep, as an occasional glitch occurred when other apps were open that appeared to interfere with the operation of this one. I rated the app for stars due to the lack of Data feed to Apples core Health application. If this feature were added, and I would rate it a five.
