What changed?
Apple says Watch Series 12 and Watch Ultra 4 introduce more frequent heart-rate and heart-rate-variability measurements, alongside a readiness feature. A redesigned iPhone Health app is planned for later this year.
What should you keep in mind?
Accuracy comparisons and expected benefits are Apple’s claims. Feature availability varies by device, language and region; the announcement should not be read as proof that every feature is immediately available worldwide.
