Hasn't been consistent. In the morning I often find the app must have crashed sometime during the night, thus no tracking. When it does work, I'm uncertain how able it is to distinguish between me or my spouse or the furry animals during their night adventures. When I compare the data (when it does work) to my smart watch's tracking it's sometimes close to matching. But otherwise a novel idea, once the bugs get fixed.

Plain doesn't work. Set alarm, says no alarm set. Says swipe up to stop tracking, swiping up does nothing. Trash app

This app is such a SCAM. I downloaded so I could get the return delivery fee of $99 waived if I so choose (that's another $99 on top of the initial $150 delivery fee), only if you download the app and use it for 30 straight days. That's 30 days of having to keep your phone charged & next to you at all times through the night, without being able to use any other apps like audiobooks, meditation apps, etc. Zero "sleep scores" from all that info and data they've got on me. Waste of time SCAM.
