Limited benefit if you don’t have Apple Watch or wearable device
Knowing I am in a dream state or awake, this app does not record it correctly. According to it, I am never in REM, never have awake periods and am way off the charts in deep sleep. Also picks up my husband’s snoring ( which I am already aware of) and even the movement of flannel sheets is picked up and sounds very loud, like crumbing a bunch of papers . The microphone is so sensitive that even breathing is listed as snoring. Other than being pretty to look at, I find this to be a less than useful tool. Also required to subscribe for one year. When cancelled, prorated refund was not given.
Smart alarm no good
The “smart alarm” woke me up exactly 1 minute into the alarm range every morning, no matter what sleep stage I was in. It doesn’t seem to be analyzing whether I’m in a light sleep stage at all.
