Mi Fit against misfits

What’s Mi Fit?

Mi Fit is an app that pairs with the fitness trackers from the Xiaomi Mi Band series. Mi Fit can track exercises as well as analyze sleep and activity data, displaying calories burned, steps walked, and heart rate. The app has over 100 million installs on Google Play and is included in the top 10 most used health and fitness apps in France and Germany.

Fitness data solving crimes

Often times, data from fitness trackers and fitness apps provides the authorities with valid evidence, helping to solve crimes. In 2019, data from a fitness tracker led to the conviction of a mob hitman in the UK. In 2018, another fitness tracker logged the last heartbeat of a murdered woman, which helped greatly in finding her killer. At the same time, smart wearables can also provide their owners with an alibi.

Mi Fit support

Data from MiBand and Amazfit wearables is synchronized with the Mi Fit app, which can be installed on Android or iOS device. The app is also compatible with Mi Body Composition Scale, Mi Scale, Amazfit Pace, and Amazfit Smart Chip. Mi Fit can be used without any smart devices connected, however, in this case, its functionality will be limited.

In Oxygen Forensic® Detective v.14.3, we have enabled data extraction from Mi Fit cloud, and both iOS and Android apps.

Mi Fit extraction from cloud

To start data extraction from Mi Fit Cloud, open Oxygen Forensic® Cloud Extractor from the home screen of Oxygen Forensic® Detective. If you’ve updated to version 14.3, the Mi Fit icon will be the first in the list of all available services. Select it to proceed.

An investigator can get authorization in Mi Fit cloud with the user’s Mi Fit, Google, Facebook, or Mi account credentials. Another way to authorization is to use a token from an iOS or Android device, or the one that was generated when logging in with their credentials. Proxy extraction is supported for Mi Fit cloud.

It is possible to import the Mi Fit credentials or token from the Accounts and Passwords section of an examined device that has been used to log into Mi Fit. When authorizing by token, note that the token is only valid till a new authorization in Mi Fit occurs.

Once authorized in the cloud, Oxygen Forensic® Cloud Extractor proceeds to acquire data from it. The process may take some time, the duration depending on the volume of available data. Investigators can get access to the following information from the Mi Fit cloud:

  • Data about the account owner
  • Linked and family accounts
  • Contacts
  • Goals
  • Alarms
  • Reminders
  • Connected devices
  • Behavior tags
  • Menstrual cycles
  • Body measurements
  • Chats
  • Workouts
  • Mi Fit Band Data

Mi Fit extraction from mobile devices

Data from Mi Fit is included into iTunes and Android backups and thus can be easily parsed during logical data extraction. Directly from mobile apps, data about account owner, their contacts, and workouts can be extracted, as well as cookies and cache.
