Report: watchOS 27 to improve heart-rate tracking; AI health coach may not debut at launch

Apple’s watchOS 27 is expected to prioritize stability and smaller refinements, including better heart-rate tracking for Apple Watch.

Bloomberg says the AI health coach project, codenamed Mulberry, has been scaled back and may miss the initial iOS 27 launch.

The redesigned Health app could arrive before the coaching features, suggesting a staggered rollout.

The changes point to Apple refining core health tracking first while delaying a bigger subscription-style health push.
