Mi Fit is Xiaomi’s health tracking hardware – it works with Mi Band, its scales as well as a range of Amazfit devices. The app has now received an update which adds REM sleep. For now, this functionality has been added only to support Mi Band 5. Earlier versions of the fitness band do not get REM sleep.
Announced a few days ago, Mi Band 5 can identify problems such as irregular and sporadic sleep patterns, along with REM sleep by utilizing heart rate variability and respiratory information. Users also get suggestions on how to improve their kip time. This is in addition to other upgrades such as a larger 1.1 inch display, barometer and more.
Issues with app
In the past few weeks some people have reported problems with the Mi Fit app. This all started after the update to version 4.1.1, which was released on May 27th. This includes incorrect synchronization of steps counted (not all the steps would sync to the app), problems with sleep tracking (incorrect figures or sleep not recording at all in the app) and issues with continuous heart rate measurements. In essence, all of these stem for poor synchronization between the app and wearable.
As usual, the change log of version 4.2.0 mentions fixing bugs so there is hope these issues will be ironed out with this latest update. Some Android users have even reverted to version 4.1.0 which is the last software iteration which works well for most people.
If you opt to do this you will need to delete the current software from your smartphone and download the older version from sites such as APKMirror server. Or you can hope for the best and install 4.2.0 from Google Play Store or Apple App Store.
