The CMF Watch Nothing X app is now the official control hub for CMF Watch devices, replacing the standalone CMF Watch app that has served users since launch. Nothing rolled out this transition to unify management of its watch and audio ecosystem, consolidating separate apps into a single interface that works faster and more reliably. If you own a CMF Watch Pro, Watch Pro 2, or Watch 3 Pro, you’ll need to migrate before the old app loses support in July 2026.
Key Takeaways
- Nothing X app unifies CMF Watch and audio device management in one interface
- Supports CMF Watch Pro, Watch Pro 2, and Watch 3 Pro with improved GPS on Watch 3 Pro
- Data migration transfers workout history, sleep, heart rate, and fitness goals from October 2023 onward
- Public beta launched June 27, 2025, with 1,000 initial spots; full rollout ongoing
- Old CMF Watch app remains functional until July 2026, then accounts deactivate
What the CMF Watch Nothing X app brings to your wrist
The Nothing X app replaces fragmented device management with a single, streamlined interface designed for faster performance and easier navigation. Nothing stated that this consolidation brings “a more stable connection, a refreshed interface, and an improved overall experience for Watch Pro and Watch Pro 2 users”. The app is available free on both Google Play and the App Store, making the switch accessible to all CMF Watch owners regardless of platform.
One meaningful upgrade is improved GPS performance specifically on the Watch 3 Pro. Users who rely on accurate location tracking for running, cycling, or hiking will notice sharper signal acquisition and more reliable route recording. The unified app also centralizes controls for CMF Watch and Nothing audio devices—headphones, earbuds, or speakers—eliminating the need to juggle multiple apps.
How to migrate your CMF Watch data to Nothing X
Before you begin, Nothing recommends unbinding your watch from the old CMF Watch app. This step prevents conflicts during the transition and ensures a clean handoff to the new system. Once that’s done, the migration process is straightforward and guided by the app itself.
Start by installing the Nothing X beta from Google Play—search “Nothing X” and join the beta programme. Open the app and connect your watch. A migration guide will appear automatically, prompting you to transfer all your data from October 2023 to the present month. The transfer includes workout history, sleep data, heart rate records, blood oxygen readings, stress measurements, daily activity logs, Active Score, training load (for Watch Pro 2), and your fitness goals. After migration completes, your old CMF Watch account deactivates and cannot be used again.
The beta programme started with limited capacity—1,000 trial spots initially—so availability may be restricted depending on when you attempt to join. However, Nothing is rolling out the app more broadly, and full availability is expected to expand beyond the beta phase.
Features and settings you can control in Nothing X
The Nothing X app puts several customization options at your fingertips. You can assign functions to the crown—the rotating dial on your watch—by navigating to My Devices, then Device Settings, then Crown shortcut, and selecting your preferred action. On the watch itself, quick-press the side button twice on the main face to activate that shortcut.
If you use ChatGPT, you can enable it directly on your watch through Nothing X. Navigate to My Devices, find ChatGPT, and toggle the switch on. The AI assistant will then be available on your wrist for quick queries. Notification wake is another option—go to Settings, Display & Brightness, and enable Notification to wake. Be aware this setting drains battery faster, so use it only if you value wrist activation over battery longevity.
Syncing workouts is seamless: pair your watch, wear it, open the Workout page in the app, and start a session. The watch will display your chosen mode and record metrics automatically. This integration eliminates manual logging and keeps your fitness data synchronized across devices.
Known issues and what’s been fixed
The beta version (v3.2.10) had one notable quirk: wearing multiple watches in a single day would inflate activity data, crediting you with duplicate steps and exercise minutes. Nothing fixed this issue by July 2025, so current users should not encounter inflated stats. If you’re testing the beta on an older version, update to the latest release to eliminate this bug.
Battery drain from the notification wake feature is a trade-off rather than a bug—it’s a design choice that prioritizes responsiveness at the cost of longevity. If battery life is your priority, leave this setting off.
What happens to your old CMF Watch app?
The original CMF Watch app will continue working until July 2026, giving users a full year-plus window to migrate. After that deadline, the app will no longer function and accounts will be permanently deactivated. Nothing is not forcing an immediate switch, but the company is clearly signaling that the old app is on its way out. Staying on the legacy app after July 2026 is not an option, so planning your migration now avoids a last-minute scramble.
Is the CMF Watch Nothing X app free?
Yes, the Nothing X app is completely free on both Google Play and the App Store. There are no subscription fees or in-app purchases required to manage your CMF Watch or other Nothing devices. The only cost is the watch itself.
Will my workout data transfer to Nothing X?
All workout history, sleep records, heart rate data, blood oxygen readings, stress measurements, and fitness goals recorded from October 2023 onward will transfer automatically during migration. The migration guide handles this process, so you don’t need to manually export or import anything. Once migrated, your CMF Watch account deactivates, so you cannot revert to the old app.
What if I don’t migrate before July 2026?
Your old CMF Watch app will stop working entirely, and your account will be deactivated. You’ll lose access to your device unless you switch to Nothing X. Migrating now ensures uninterrupted access to your watch and preserves all your historical fitness data.
The CMF Watch Nothing X app is Nothing’s bet on unified ecosystem management, and for CMF Watch owners, it’s no longer optional—it’s the future. The transition brings real improvements in speed and interface design, and the data migration process is painless if you follow the steps. Start your migration now during the beta phase to avoid the rush closer to the July 2026 deadline.
