Works beautifully

I use the sleep feature every night too. The walk reminder to move definitely gets me walking more and its great charting them. I also love the sleep charting and found the placement test works great. Charting sleep reminds me that I have to get to bed sooner and not read in bed, which keeps me up late. Another excellent app from MotionX.
1/17/13 Update: It just keeps getting better. The new pulse feature is a great health addition when you wake up.
10/13/13 Update: more improvements with the weight tracking and sleep log show in the large bar chart automatically when you rotate the phone. Havent tried the snore recorder cuz I dont snore.
2/19/14 Update: I didnt lose any data that someone else mentioned in another review.
11/17/14 - Still rock-solid. iOS 8 color scheme is different but usable
10/19/16 - alarm started crashing, support suggested database was corrupt and recommended resetting. Worked fine since then.
