5 stars: I have a T-Rex Pro, lots of negative reviews, but outside the GPS being a. It off synced (still looking at the cause) it's fantastic, and I am never going back to Zepp app. So much capabilities if you don't mind the steep learning curve. I got pro version, no regrets thus far. I look forward to future refinements and improvements. Battery life is fine so long as you don't run Zepp and this simultaneously. You are going to have to pick one
5 stars: This app have my bip a new lease on life! I was getting very frustrated with the notifications from the original app, they would show for a split second then go to notification count. This app shows the count plus notification, even more than one notification on the same screen! Thanks so much!
4 stars: This app has come a long way and has a ton of customization options. End of September 2022, AmazFit pushed an update that fixed several things and it seems that my GTR 4 works with Notify again. However, I see no reason to use notify for notifications, at this time, as the native app (Zepp) allows for replies and Notify does not.
4 stars: That's an awesome app. Now the problem with connectivity is gone. The interface can be better, because it's easy to be lost inside the app seraching for an option or setting. NOTE: I'm a PRO licence user.
3 stars: The best option out there. Works ok-ish for my need. I use it primarily for getting bed-reminders and tracking with Sleep as Android (Bip S). It's buggy and glitch...
