Apple’s revamped Health app will calculate your ‘health age’ and readiness score

Apple’s redesigned Health app, released with the Apple Watch Series 12 and Ultra 4, adds an Insights tab that shows a “readiness” score and computes a “Health Age” by comparing metrics such as VO2 max, sleep and blood biomarkers to the user’s chronological age. A new Longevity tab aggregates sleep, movement, heart-health and lab data—including a Quest-partnered 50-biomarker panel priced at $119—to deliver personalized guidance, interval-training suggestions and movement assessments with on-screen trainer demonstrations.
