What changed in 2026:
- Wear OS 5 compatible with iPhone (with limitations)
- Some Garmin, Fitbit, and Amazfit watches work perfectly on both systems
- Apple Watch remains iOS exclusive (no changes)
- Samsung has opened up Galaxy Watch to iPhones (with reduced functionality)

A: No, it's technically impossible. The Apple Watch requires an iPhone for activation and operation.
