Do the Apple Watch Series 12's New Health Features Live Up to the Hype?
I now have the Apple Watch Series 12 in my hands—or, rather, on my wrist—and have spent the past 24 hours putting it through as many tests as I can manage. I'm pleased with the step counting and the availability of "recovery HRV" (as opposed to the cardiac-health-focused HRV that the Apple Watch previously used) but I'm not sure if the heart rate accuracy is living up to the hype. I'll be putting this device to more rigorous tests, but here are my first thoughts.
