Invasive, Intrusive, infuriating. I have more than 1 x Bluetooth device - believe it or not, as do billions of other people. When I want to use other devices, I should be able to without being bombarded with this app trying to connect. when I force stop the app, I don't want it to appear 1 second later draining phones resources. When I want a different watch face, it should not need to delete the previous face. How pathetic - 1 watch face at a time? Asks for a huge amount of permissions.

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!

is there an alternative for this app? i would like to test a few so that i can truly rate it in comparison to the others. for example, i prefer dd/mmm date format, i only want day, date, and battery percentage on the numbered round watch face, i want the contacts in the watch not to delete when i disconnect and reconnect the app, i don't want ads on an app whose watch i paid for, the weather information is not reliable, etc which are options that this app doesn't offer. thank you.
