If there was 0 stars I'd put 0. With this app it behaves just as an analog watch does. It connects to Bluetooth but will not connect to the phone. I can't personalize anything with this app. I am not able to change the wall paper because it will not connect. can't do any of the other functions that I'm supposed to be using. Unfortunately there is no other app that will work with my watch. I am about to buy me a new watch that uses a different app. This app is ridiculous!!

The sleep tracking mode has only worked a few times before stopping completely, and keeping track of other modes is difficult requiring the user to constantly add the data instead of having the data automatically added. Also the subscription price is about the same as what I paid for the watch while not disclosing that a subscription was needed. If I had known that I would have gotten a better watch, like the Samsung smart watches or other high end smart watches or rings!!

The interface is set and cannot be customized to display exactly what I would like. Viewing my cycling data is confusing and appears incomplete, not tracking my full route, and there appears to be two different categories of data, one for my track and another section of biometrics. I would like to be able to see my biometrics while I was cycling! I would not recommend this app, but as far as I know devices are not comparable with other apps, which is disappointing, I love my device!
