1. The CMF Watch app was removed from app stores, and future management will be via the Nothing X app starting July 19th, 2026.
2. Users can transfer key health and activity data from the CMF Watch app to the Nothing X app, but some data will be lost during migration.
3. Post-migration, the CMF Watch app account will be deactivated and the app can be deleted; the new app aims to offer a better user experience with higher ratings.
The CMF Watch 3 Pro, priced at around $90, and previous smartwatches from the CMF line, which is a sub-brand under Nothing, used to connect with your iPhone or Android device through the CMF Watch application. Changes are now happening as Nothing officially announced, the app has been removed from both the App Store and Google Play Store on April 3rd. This move marks a significant shift in how users will interact with their devices.
Transition to the Nothing X App
Starting from July 19th, 2026, all versions of the CMF Watch will need to be paired and managed using the new Nothing X application. This app, which is free to download, is now the primary tool for users to control their smartwatches. Transfering data such as workout history, fitness goals, activity scores, sleep logs, heart rate, blood oxygen levels, and stress data will be possible through this app. Users will need to migrate their essential information from the old CMF Watch app to the new app for a seamless transition.
Data Migration and User Experience
However, some information will not make the jump, like weight, height, custom watch face settings, and cycle tracking details. When the migration is done, the old CMF Watch app account will be deactivated and the app can then be uninstalled from the device. To initiate this process, users must select the “Data Migration” option in the Nothing X app while their CMF Watch is connected to their smartphone. Despite the inconvenience of losing certain data, the overall user reviews show a notable improvement. The old CMF Watch app was rated 3.2 out of 5 stars, whereas the new Nothing X app boasts a higher rating of 4.4 stars, hinting at better overall user satisfaction with the new management system.
