5 stars: Good App, syncs quickly and without issue. I have the Amazfit Bip U Pro and I cannot fault it for accuracy, the built-in GPS is excellent (especially considering the price) I would say the Beta
4 stars: A few things to note.. **MOST IMPORTANT** You no longer have to go through all the auto-on steps if you have a Samsung device. It will automatically do it for you as of latest update. This information should save you a lot of time. Next, SMS Auto Reply is for REJECTING calls. Not for quick replying incoming SMS messages. The app gets 4 stars for the lack of this information.
3 stars: connects quickly most of the time. sometimes have to close app and relaunch. notifications to gtr 3 pro work, then don't. then days later work again. sms quick reply doesn't work at all. they did the first couple of weeks I had the watch. support is super slow to respond and as helpful as what you can Google yourself. sleep tracking seems accurate. I don't use for walking or workouts.
2 stars: The GPS wasn't all that good to begin with and now after a few months it's a lot worse. It will show the starting point for a walk being a block or more from where it actually is and during a straight line walk it wanders off in other directions which makes the distance, calories burned etc inaccurate too. Basically it's not much use for anything other than a wristwatch so I guess I'll just pay more and buy a good fitness tracker.
2 stars: I've been using this app with my Amazfit Pa...
