Heart rate not working or intermittent

If you bought this application and heart rate is not working or the measuring is intermittent, please follow this guide carefully:

  • Install latest version of Mi Band Tools available on Google Play
    • Restart your phone afterwards
  • Still not working? Please perform the profile synchronization by carefully following all these steps:
    • Restart your phone
    • Synchronize your bracelet with original Mi Fit application
    • Open Mi Band Tools and tap the bluetooth icon in upper right corner
    • Wait about 60 seconds
  • Still not working?
    • If this happens, the most likely issue is that you have used, or scheduled, some kind of task killer, power saver, or RAM saver program. If you use a task killer to stop background processes our application services will be stopped too. You will have to restart your phone each time you use such a program in order to keep Mi Band Tools working. If you use such a program, we suggest you look for a setting that lets you not kill anything related to Mi Band Tools (add exception for this application). You can close the main Mi Band Tools application to save RAM, but the application service must not be stopped.
    • Please ensure that you thoroughly check your phone for features like RAM savers or power savers. Sometime these will be in settings, and not stand alone applications. We cannot provide help or support for non generic or manufacturer specific Android features.
    • In some cases, enabling Smart Lock (if your Android version supports it) for your Mi Band also increases overall stability, we highly recommend doing so.
    • We strongly suggest that you uninstall task killers if you can not find an option to add an exception for Mi Band Tools. 
    • If you have these issues, always enable Status Bar Notification for Mi Band Tools (go to Mi Band Tools - Settings - Status Bar Notification and turn it on), enabled status bar notification tries to prevent Mi Band Tools process from being killed by your system.
    • Very important is also to configure your Android 6+ Doze mode feature correctly. Add an exception for Android Doze mode feature for Mi Band Tools and Mi Fit.
  • Still not working?
    • Perform full clean installation for both - Mi Band Tools and Mi Fit application:
      • Uninstall Mi Band Tools
      • Uninstall Mi Fit
      • Restart your phone
      • Install Mi Fit and pair it with your bracelet
      • Fully synchronize your bracelet with original Mi Fit application
      • Install Mi Band Tools and carefully follow all instructions (e.g. profile synchronization, notification access for Mi Band Tools, notification access for Mi Fit etc.)

If you never bought this application and heart rate is not working, the reason is pretty obvious. Mi Band Tools contains an antipiracy mechanism that automatically and silently turns communication off when it detects that your version of Mi Band Tools is not genuine. Please do not support piracy and buy legitimate copy of Mi Band Tools to support the developer. Please note that we only provide support for legitimately bought versions of the Mi Band Tools application. If you require any form of support, you need to tell us your Google Play order number. If you won't provide one, we won't process your email request.
