Some things great, some things not so great – SleepSpace - Tracker & Coach Review

The good news is that the functions of the app that relate to sleep itself are wonderful. Everything from falling asleep programs, noise masking, deep sleep stimulation , and wakeup alarms are automated in an easy to use and integrated package that replaces three of my earlier apps. The bad news is that the sleep tracking is pretty much third rate and cannot compete with other iOS sleep tracking apps. There is no visible tracking of deep versus restless sleep, few useful stats, no way to incorporate naps, and worst of all it really drains your battery life because I believe it is tracking your heart rate every second. Given the above, I think the price is way too high for the monthly subscription. So, either the sleep tracking needs to be fixed/improved greatly or the price should come down. (I have not yet taken advantage of the live "sleep coaching" features so no idea if this adds value.) Another plus is that the dev is highly responsive in providing support.
