CMF Watch users must migrate to Nothing X starting April 3, 2026, when the dedicated CMF app vanishes from stores, forcing a platform shift. July 19, 2026 marks the full takeover of watch pairing and data management. Users can begin transferring data now, but workout records, daily activity, and sleep data will move, excluding nicknames, avatars, and health info. The CMF Watch 3 Pro, launched in July 2025, offers a 1.43-inch AMOLED display and 131 sports modes, positioning CMF as a budget sub-$200 brand after a $100M investment spun it off from Nothing.

Android Central notes the transition aims for seamless user experience despite the platform change.
