Apple's New 'Health Age' Feature Joins a Crowded Field of Dubious Biometric Scores

Apple announced a longevity feature called Health Age at its recent Apple Watch event, set to launch later this year alongside a redesigned Health app and a new readiness metric. The feature estimates a user's physiological age based on health and fitness data, a concept already used by other wearable brands. Verge senior reviewer Victoria Song expressed skepticism at the announcement, noting that similar metrics from competing platforms have produced inconsistent or counterintuitive results. The broader concern is that so-called 'health age' scores may give users a misleading picture of their actual wellbeing. Such biometric age estimates remain a contested area in consumer health technology, with their scientific validity widely debated.
