During next days you will be able to get new update of Bind Mi Band, that has new feature - OneDrive synchronization of steps history!
All you need to make it work - just grant a permission through History page and it will silently keep up to date copy of activity history in your OneDrive. If you suddenly uninstall the app or change a phone, it will grab latest info and fill your phone database with historical data.
Also, in this update we added support of French, Turkish and German languages, corrected mistakes in some other translations! If you see any errors, please, feel free to email us.
Just a note: having OneDrive synchronization doesn't mean that you can all the time switch between devices during one day, there are still some difficulties with this on Mi Band's side that lead to some discomfort, but they may be overcome in future :)
You may ask why is cloud sync done now? Because during next 1-1.5 month there will be big redesign of the app. So we need to have BETA testers to check all that. We want for them it to be comfortable to switch between several app versions.
Next big update will handle much more activity information, will do more intelligent analysis and keep more detailed history, including sleeping and walking intervals.
P.S. We are still searching for updated version of Mi Band (FW 5.x.x.x) and if we find it, then it is top priority for us to add support of it to the app.
