Apple Watch Series 12’s ‘Health Age’ takes on WHOOP’s health tracking

Apple is pushing the Apple Watch further into the health-tracking territory traditionally associated with devices such as WHOOP, with the new Apple Watch Series 12 turning a stream of health and fitness data into a single read on how ready a user is for the day.

Launched on Wednesday, the new Apple Watch comes with a new Health Sensing System and S11 chip that allow it to measure heart rate every five seconds throughout the day. It also measures heart rate variability (HRV) more frequently and uses activity, sleep and vitals data to tell users how ready their body is for the day.
