What is gadgetbridge

IT security | Data protection | Hacking ➡ microblog

As part of a larger project for a health insurance company, I am currently testing the widely used Xiaomi Mi Band 2 fitness bracelet. Among other things, it can be used as a sleep tracker, activity tracker and heart rate monitor.

The official app from Xiaomi (Mi Fit) but also other solutions such as Notify & Fitness report to Facebook immediately after starting the app. How dubious the integration of Facebook components (SDK) is in terms of privacy is now well known.

But that's not all. By purchasing or using the official app, you are forced into an ecosystem controlled by the manufacturer. Before use is even possible, you first have to set up an account with the manufacturer, agree to the (incomplete) data protection regulations and then all recorded data also flow to the manufacturer. From a privacy perspective, this is a no-go.

There is an open source alternative in which all data remains with the carrier: Gadgetbridge. The app can even be obtained from the F-Droid store and supports numerous devices:

  • Amazfit Bip
  • Amazfit Cor
  • Casio GB-6900B (WIP)
  • HPlus Devices (e.g. ZeBand)
  • ID115 (WIP)
  • Lenovo Watch 9 (WIP)
  • Liveview (WIP)
  • Mi Band, Mi Band 1A, Mi Band 1S
  • Wed Volume 2
  • Wed Volume 3
  • NO.1 F1 (WIP)
  • Pebble, Pebble Steel, Pebble Time, Pebble Time Steel, Pebble Time Round
  • Pebble 2
  • Teclast H10, H30 (WIP)
  • XWatch (Affordable Chinese Casio-like smartwatches)
  • Vibratissimo (experimental)
  • ZeTime (WIP)

My tip: Uninstall Mi Fit and the like and use the Gadgetbridge. Your fitness data remains with you and the range of functions is even greater - at least with the Mi Band 2.

By the way, firmware updates of the Mi Band 2 can also be carried out without the official app: Mi Band 2 Firmware Update.
