Our verdict
Mi Fitness suits people who own or plan to buy a Xiaomi or Redmi band or watch and want a free app for health, sleep and workout data. The trade-offs: it only serves Xiaomi's own devices, sells watch faces and a VIP plan with unstated benefits, and its privacy documentation does not say where data is stored.
Best for: Owners of Xiaomi or Redmi bands and watches who want the official app
Skip it if: Owners of other brands' wearables, since the app supports only Xiaomi and Redmi devices

Cons
- Works only with supported Xiaomi and Redmi devices

Experience & key features
What it is
Mi Fitness is Xiaomi's app for connecting and managing Xiaomi and Redmi bands and smartwatches. Per iTunes data, the App Store listing dates from 8 July 2020, when it was called Xiaomi Wear. In 2022 Gadgets & Wearables reported that Xiaomi renamed Xiaomi Wear to Mi Fitness and the older Mi Fit app to Zepp Life. The App Store title is now Mi Fitness (Xiaomi Wear Lite).
Key features
According to the App Store description, the app records walks, runs and rides with routes and monitors heart rate, sleep, stress and energy through the day, with risk warnings. Sleep reports break down deep, light and REM sleep along with sleep heart rate and breathing quality. Weight and women's health can be logged manually. Some devices can link a Mastercard for payments. Version 3.55.0 improved data display on the blood pressure, blood glucose and body temperature pages.
Pricing and value
The app is free to download. The US App Store lists eight paid watch faces at $0.99 each, a monthly auto-renewing VIP plan at $2.99 and an annual card at $14.99. The store page does not say what VIP includes, so check the in-app purchase screen before paying. For existing Xiaomi device owners, the core features cost nothing extra.
More analysis
Privacy
Xiaomi's IoT white paper says Mi Fitness encrypts data in transit and at rest, keeps card details on the device, and lets users turn off cloud sync so workouts stay off the server. Users can download a copy, delete server data through the Mi Account Privacy Center, or withdraw consent in the app. What is missing: the document does not say in which region data is stored, and this research found no dated policy for the global app, so users should read the policy shown in the app.
Versus alternatives
Mi Fitness is only useful with Xiaomi or Redmi hardware; Samsung, Huawei, Garmin or Amazfit owners need their own makers' apps. Against other free companion apps, its strengths are broad tracking and low cost, and its weaknesses are a narrow ecosystem and privacy documents that leave out where data is stored.

Cancellation & refunds
No Xiaomi-specific refund policy for in-app purchases was found; App Store purchases are handled by Apple under its own rules.
Privacy
Xiaomi's IoT privacy white paper has a Mi Fitness section: app-server traffic uses HTTPS, sensitive data is encrypted at rest (AES-256, AES-128), and payment card details stay on the device. Users can skip gender, height and weight (the app uses defaults), turn off weather to stop rough location collection, and turn off cloud sync to keep workouts off the server. Data can be downloaded or deleted from Xiaomi's servers through the Mi Account Privacy Center, and consent withdrawn under Profile > About this app. The data inventory includes device identifiers, contact details, health and fitness data and precise location. The white paper does not say in which region global users' data is stored, and this research found no dated, Mi Fitness-specific policy for the global app. The App Store privacy label (self-declared by the developer) lists health, financial, location, contact and identifier data as linked to the user.

Why this score
Ratings are high on the App Store (4.6 to 4.8/5) and Google Play (4.5 to 4.8/5), but unitQ scores it 71/100, labelled "good", which points to a fair number of reported issues.
Why this score
The App Store description lists mapped workouts, heart rate, sleep stages, stress, energy, manual weight and women's health logging, and Mastercard payments on wearables. Solid scope, but tied to Xiaomi hardware.
Why this score
A free download with core tracking at no charge. Points are lost for paid watch faces and a VIP plan whose benefits are not stated on the pages read.
Why this score
The iOS app is 722 MB per the App Store, and version 3.55.0 shipped on 5 Nov 2026 with bug fixes. unitQ logged 7,764 reports over 30 days, 84% from Android. With no independent speed data, the score stays neutral.
Why this score
Xiaomi offers a privacy centre, a white paper and a data-request form, but this research could not verify a direct customer support channel for the app.
Why this score
Encryption, data download and deletion, consent withdrawal and a cloud-sync switch are all documented. Points are lost because there is no dated policy for the global app, storage location is not disclosed, and the app collects precise location and financial data linked to identity.
