5 stars: It is an excellent app, I have a mi band 4, and it is very accurate, as it shows accurate results of my steps,heart rate,and my sleep, the UI of the app is so beautiful. Many people say that the recent update of mi fit is not working, but for me nothing is happening, the app is working fine just as before this recent update. Mi band 4 is the best fitness band. I love it !!😊😊
4 stars: Software is good, and the Mi Smart Band 5 is much better than the previous. Sleep tracking is improved, and it detects naps. Step tracking is very much improved. I haven't seen any improvement of the heart rating, but I'm still testing it out. Battery does last a little less, with the average being 8 to 9 days. Perhaps changing the heat sensor periodicity might extend that further. No GPS though. Let's wait for 6!!!
4 stars: Sadly the update in late June had messed up the GPS system. The GPS map was not recording my route correctly. There have been 3 further updates but GPS was still not coordinating correctly. This week the App suddenly began to operate correctly (as before). I have not changed any settings, nor have I noticed an update? But now happy with detailed report.
3 stars: Since one update that happened mid June, sleep score is bugged. Even in nights that I haven't the recommended deep sleep I receive 100 score. After the update, nights that I had 90 score or even lower increased to 100. That is happening with mi band 3, 4 and even the 5 (got mine yesterday). Plea...
