Apple could put its AI-powered health coach project back in the spotlight as early as September, alongside the next Apple Watch models. 9to5Mac has revived discussion of Project Mulberry, a project that has reportedly been delayed and scaled back but may still be part of Apple’s plans.
The concept predates the latest rumors. Reports in 2025 pointed to Project Mulberry, an ambitious overhaul of the Health app centered on an AI agent that could interpret Apple Watch data and offer personalized guidance. At one point, the plans reportedly included a separate Health+ service featuring content from doctors, nutritionists and other specialists.
The plan appears to have changed course. In February, reports suggested Apple had reduced the project’s scope, opting instead to introduce features gradually within the Health app. WWDC 2026 passed without the anticipated major redesign, and the features are not expected in the initial iOS 27 release.
That does not necessarily mean another year-long delay. Apple has often reserved health-related announcements for its September events: Low Power Mode in watchOS 9, sleep apnea detection and hypertension-related notifications were all introduced in the autumn rather than at WWDC. This year, Apple has officially scheduled an event for September 9, where the Apple Watch Series 12 and Ultra 4 are expected.
What could remain of Mulberry? First, an AI coach that analyzes data already collected in Health and provides contextual explanations and recommendations. Another reported idea is using the iPhone camera to track an exercise session and provide feedback on form. A Health app redesign is also said to be under consideration, which would make sense as the app has become a repository for heart-rate, sleep, activity, medication and other data that many users may find difficult to interpret.
The timing would also fit Apple’s apparent effort to put health back at the center of its 2026 Watch lineup. Recent reports have pointed to Apple Watch Ultra 4 and potential improvements to hypertension-related features. The hardware already gathers a substantial amount of information; Apple’s challenge is turning it into guidance people can actually understand.
For now, everything remains rumor. 9to5Mac considers a September announcement plausible, but the features may not ship until iOS 27.1 in October—or later. After several reported schedule changes, September 9 should provide the clearest indication of whether Apple’s AI health coach is ready.
