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

For the better part of a year, we’ve been hearing about Project Mulberry : Apple’s AI-powered health coach. Back in February, it was reported that these efforts had been scaled back. This piece sits on 1 source layers, but the real value is showing why the story should not be skimmed past too quickly.

For the better part of a year, we’ve been hearing about Project Mulberry : Apple’s AI-powered health coach. Back in February, it was reported that these efforts had been scaled back. According to Bloomberg’s Mark Gurman , the features should still be on track for iOS 27, though they may not release until later in the cycle. 9to5Mac is the main source layer for now, and the rest should be read as a signal that is still widening. On the device side, the useful angle is whether a technical change actually alters feel, lifespan, or upgrade cost in real use.

What is happening now

For the better part of a year, we’ve been hearing about Project Mulberry : Apple’s AI-powered health coach. 9to5Mac form the main source layer behind the core facts in this piece. This is still a developing thread, so the useful part is knowing which source signals are hardening and which ones still need caution. With devices, practical impact usually shows up in battery life, heat, stability, and long-term usability rather than in a few flashy headline numbers.

Where the sources line up

The details worth keeping

According to Bloomberg’s Mark Gurman , the features should still be on track for iOS 27, though they may not release until later in the cycle. On the device side, the useful angle is whether a technical change actually alters feel, lifespan, or upgrade cost in real use.

Why this matters most

The signal is strong enough to deserve attention, but it still needs to be read as something developing rather than fully settled. With 1 source layers on the table, the part worth reading most closely is where firm facts meet the market's early reaction. On the other hand, Apple is apparently going to greatly improve Apple Watch heart-rate tracking with watchOS 27, which could tie in nicely with Apple’s eventual health coach.

What to watch next

The next readout is price, device coverage, and whether the change feels real once the hardware reaches users. Patrick Tech Media will keep checking rollout speed, user reaction, and how 9to5Mac update the next pieces. From 1 early signals, the piece keeps 1 references that are useful for locking the main details in place.
