4 stars: So far it's been a very solid experience. The app is a little slow in syncing dials with the watch, but I would be an asshat to say the 40- 80 seconds I've had to wait really inconvenienced me in any way. It would be amazing to see the watch faces available changed out or updated on a regular basis, would add a lot of longevity to the product and overall experience.
4 stars: better than I originally thought actually. For quite a while the app wouldn't track my sleep and couldn't figure out why. apparently the watch wasn't making correct contact with my arm. I adjusted it and now everything works as it should. I would give it 5 stars but the english localization is a bit rough and I sometimes don't know what they were trying to say with the words that were used.
4 stars: Please adjust the sleep information, so that we can change our sleep time. I don't like that the app assumes I am asleep until I use the app. I wake earlier, but cannot change the wake time to show that. It makes it difficult to know how much sleep I actually got. It should be fairly easy to make it so the user can change the time to when they really woke up. Otherwise, the app has worked well.
4 stars: There's only preset dials nothing that you can choose yourself. Biggest problem I have is once a week for some random reason it stops calculating steps. For that fix I just unbind it disconnected from the phone and turn it off turn it back on and reconnect and it will calculate steps again....
