Overview
- Multiple outlets reported Tuesday that discoveries in watchOS 27 and iOS 27 beta code, posted by a forum contributor known as “pdfu,” reference a new preinstalled Readiness app placed next to Workout in the Watch home screen.
- The same beta files include identifiers for an optical‑sensing family called Sunstone4p0, which suggests improved heart‑rate sensing and the possibility of continuous heart‑rate tracking outside of workouts.
- watchOS 27 code shows expanded workout data structures able to record individual sets, reps, weight, equipment and side of the body, pointing to much more granular strength‑training logging in Workout.
- Firmware tied to a T8320/S‑class chip in the betas contains a storage profile that maps to roughly 128GB of internal storage, up from the current 64GB, although that could be hardware‑dependent.
- Reports emphasize these findings are based on unreleased beta code and a pseudonymous leaker, so features may be hardware‑limited, changed, delayed or not ship as described and final details are expected at Apple’s Sept. 9 event.
