The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular wearables thanks to its combination of affordable price, long autonomy and wide functionality. However, many users face the first difficulty in the connection stage: which application should be downloaded to make the bracelet work? On the Internet, you can find dozens of mentions of various programs, from official to third-party, which only adds to the confusion.

Xiaomi regularly updates its services, and app names can vary depending on the region or version of the bracelet firmware. For example, in 2019-2020, one application was used for the Mi Band 4, and in 2021-2026 another, with advanced features. If you download the wrong program, the bracelet may not sync, not show notifications or not connect to the phone at all. In this article, we will analyze the exact names of the official applications for the Mi Band 4 for 2026, and also tell you how to install and configure them correctly.

• 📱 I bought a bracelet from my hands and do not know what software I need for it;
• 🔄 Updated the smartphone and lost the old app;
• 🌍 It is located in a region where Xiaomi is blocking access to its services (e.g. in some countries in Europe or Asia);

The official application for Xiaomi Mi Band 4: name and versions

Since the 2019 release of the Mi Band 4, Xiaomi has used two main wristband management apps:

1. Mi Fit is a classic app that supports all Mi Band models up to version 6, and it was recommended to install it when buying the Mi Band 4 in 2019-2021.
2. Zepp Life (formerly Amazfit) is an updated version that replaced the Mi Fit and became universal for Xiaomi, Amazfit and Zepp devices. Since 2022, it is the main application for the Mi Band 4.

Alternative applications for Mi Band 4: pros and cons

Here are the most popular alternatives:

1. Remove the official application (Mi Fit or Zepp Life)
2. Reset the bracelet settings (clutch the sensor for 10 seconds before vibration);
3. Install a third-party app and follow its instructions.
