It’s ok, but not the best
Not really liking it so far. The syncing ability isn’t all that great. Every time I open the app it starts syncing. It doesn’t really work if I don’t open the app. Sleep tracking isn’t that great either, because it’ll stop tracking your sleep if you get up to use the bathroom or any other movement. So if I fall asleep and get up to use the bathroom, and go back to bed and go back to sleep, it’s no longer tracking or recording my sleep. And that was my main reason for buying it. Read more
