Control your CMF Watch with the Nothing X app
Nothing X, now live with full support for Watch Pro, Watch Pro 2, and Watch 3 Pro, replaces the CMF Watch app as your control centre for settings, updates, and detailed fitness insights. This change brings a more stable connection, a refreshed interface, and an improved overall experience. The CMF Watch app remains available until July 2026 to give everyone time to switch.
How to move your data from the CMF Watch app
Unbind your watch in the CMF Watch app.
Pair the watch in Nothing X. A Data Migration Guide appears automatically.
Select a date range from October 2023 to today. The data migration transfers workout records, daily activity, sleep, heart rate, blood oxygen, stress, active score, training load on Watch Pro 2, and fitness goals.
Once migration begins, your CMF Watch account is deactivated and cannot be accessed again.
Nickname, birthday, gender, avatar, height, weight, female health data, and custom watch faces do not migrate. Re-enter these details in Nothing X for accurate tracking.

Open Nothing X and go to My Page → Support → My Devices → Send Feedback.
