Overview
- Citing Bloomberg reporting from late May, Apple plans a modest watchOS 27 that centers on stability, smoother performance, and bug fixes rather than major new capabilities.
- Multiple outlets report watchOS 27 will include measurable improvements to heart-rate tracking aimed at more consistent and granular background readings for workouts and daily monitoring.
- Apple has scaled back Project Mulberry, its AI-powered health coaching effort, and now expects those features to arrive later in the iOS 27 release cycle instead of with the initial watchOS 27 launch.
- Recent internal moves may be shaping the shift in priorities: Apple Watch and health marketing leadership changed after Stan Ng’s April retirement and oversight of the non‑invasive glucose project moved to engineering lead Zongjian Chen.
- Analysts say the quieter watchOS update reflects pressure from screenless trackers like Oura and Whoop and signals that Apple will likely roll out further health features in phased iOS/watchOS 27.x updates and a redesigned Health app.
