AI-summarised brief · reviewed before publication

The Apple Watch Series 12 impressed reviewers as a solid replacement for WHOOP fitness trackers, offering an always‑on heart‑rate sensor and a redesigned Health app. The new app, previewed briefly in iOS 27.2, introduced features such as Readiness, Health Age, integrated Vitals and Sleep data, and a cleaner interface. Apple removed the beta after a short run, promising a return in a later iOS beta—likely 27.3—before a full release by year‑end. The author praises the app’s usability but misses WHOOP’s sleep‑based day tracking, which aligns activity logs with the user’s actual rest cycle rather than a fixed 24‑hour clock. He suggests Apple adopt this approach to improve fitness goal accuracy. Adopting sleep‑aligned days could refine calorie estimates and recovery metrics for athletes.
