Thank you, best sleep tracker

Docter Hight

I am suffering with sleep issues and wanted to try apps that tracked sleep, I used for a few nights and got no deep sleep rating, so I did a blind test and got my wife to wear it, so same watch, same bed different person. I wanted to see if it really saw deep sleep. It does it tracked her and saw the deep, rest etc. On the bad side shows had bad my sleep is, but I know the data is true as we both show completely different sleep patterns. Then I emailed support, it turns out I can fiddle with the settings. Once I lowered the sensitivity, my sleep data is showing up correctly. I am happy, just wish the instruction is easier to find, but otherwise it is a great app.

Absolutely outstanding


Accuracy better then you could begin to imagine, this wonderful app accurately shows you everything you ever wanted to know about your sleep but were afraid to ask, and could not ask (because you are sleeping)! The graphs and statistics are easy to understand, but once you’re grasped them really this is an outstandingly serious aid, to call it an ‘app’ does not do it justice. This is nothing short of miraculous. Thank you so much devs for this incredibly useful intelligent aid to understanding my sleep. Brilliant.

Could be Better


I love the fact that it automatically tracks my sleep but my issue is that it often overmeasures my sleep. Like it says I slept for 13 hours a few days ago but I really only slept for seven. I had sedentary activity for the first five hours. I even got up and walked to my car and drove home during those five hours and somehow, they were still counted towards the time I was asleep. I wish there was an edit button so can could edit out those five hours and make it more accurate. When it doesn't overestimate, it is awesome because it is usually pretty accurate.

Developer Response

Please try lower the sensitivity to filter out sedentary activity. Also, please make sure all permissions are enabled. Check diagnostic #1 in Settings tab.
