Overview
- Apple introduced the Apple Watch Series 12 and Apple Watch Ultra 4 with a new S11 system chip and redesigned Health Sensing System that takes background heart‑rate readings every five seconds and measures HRV far more often than prior models.
- The company added new health tools including a Readiness score, a Health Age metric and a Longevity tab inside a redesigned Health app, with some software features scheduled to roll out later in 2026.
- A built‑in microphone and Apple’s Audio Intelligence deliver sound alerts, conversation recall features and a Siri recap, with Apple saying raw audio is processed on the device to protect privacy.
- Ultra 4 boosts battery life to up to 50 hours of normal use and up to 84 hours in Low Power Mode while Series 12 improves outdoor workout endurance; Apple also highlighted recycled titanium and a return of ceramic cases.
- Apple cites in‑depth clinical validation and existing FDA‑cleared functions to support its health claims, a move that positions the company against recovery wearables but is likely to prompt regulatory and privacy scrutiny.
