A WHOOP user says Apple Watch Series 12, with a redesigned Health app in iOS 27, adds a Readiness score based on HRV and more frequent heart-rate sampling (every 5 seconds) to deliver clearer health data, making switching back seem plausible despite WHOOP’s faster data cadence and the Watch’s screen utility.
DC Rainmaker’s in‑depth look at the Apple Watch Ultra 4 highlights a hardware refresh (new S11 CPU, upgraded HR sensor, longer battery with extended GPS modes), plus Readiness Score and daytime HRV trends, and on‑device Audio Intelligence such as instant Shazam. The watch delivers strong HR and GPS performance and a redesigned Health app is coming later this year, but it still shows gaps in mapping/navigation and occasional software quirks. Overall, it’s a solid upgrade for Ultra owners and iPhone users, with caveats around navigation, data quirks, and implementation details.
The Apple Watch Ultra 4 introduces a redesigned 32-electrode health sensor array for more ECG data, a new S11 processor for efficient background tasks, and substantially more frequent heart-rate and HRV readings (every 5 seconds and every 5 minutes, respectively) alongside a real-time Readiness score. It adds AI audio features like Live Rewind and Siri Recap, uses transcripts instead of storing audio, and includes two endurance-focused battery modes (Extended Workout up to 25 hours and Max Extended Workout up to 48 hours) with roughly 50 hours of total battery life. Priced from $799, it ships September 18 after preorder.
