Overview
- Code fragments uncovered in watchOS 27 and iOS 27 betas and reported Monday show references to a standalone Readiness app placed next to the Workout app in the watch launcher, suggesting a dedicated recovery or training-readiness feature.
- The same beta code adds a richer strength-workout data model that can store individual sets, repetition counts, weight, equipment type, body side and per-set duration, which would change how resistance training is logged on the Watch.
- Files in the betas reference a new optical-sensing family called Sunstone4p0 with lower noise coefficients and orientation-based channel selection, which developers and reporters say could indicate improved heart-rate sensing if new hardware ships.
- A NAND profile tied to a T8320 chip appears in the firmware and maps to roughly 128GB of storage, which would double current flagship Apple Watch capacity if that configuration reaches shipping devices.
- All of the findings come from unreleased beta code and a MacRumors forum poster named pdfu so they remain plausible but unconfirmed until Apple announces details at its Sept. 9 event and clarifies which items require new hardware versus software updates.
