Overview
- Sunday’s reporting, led by Bloomberg and echoed by trade outlets, says watchOS 27 will center on stability, performance and modest user-facing refinements rather than major new features.
- Multiple outlets report the update will include unspecified improvements to Apple Watch heart-rate tracking aimed at making fitness and health data more accurate and consistent.
- Bloomberg’s coverage indicates Project Mulberry, Apple’s AI-powered health coaching effort, was scaled back under recent leadership changes and is unlikely to ship with the initial iOS/watchOS 27 release.
- Apple has shifted internal responsibilities for health projects after recent personnel moves including Stan Ng’s retirement, Kaiann Drance’s expanded role, and transfer of non-invasive glucose monitoring oversight to Zongjian Chen.
- The cautious software-first approach reflects limits on on-device AI memory and growing competition from other wearable makers, and it raises the prospect that Apple will stagger AI health features into iOS 27.1 or later updates while prioritizing data quality first.
