Apple Watch Set to Gain AI Health Insights, Health Age and Longevity Features

Leaks suggest Apple Watch is headed for a major health update: on the software side, AI-generated health insights powered by Apple Intelligence; on the hardware side, new S12 and Ultra 4 models. Multiple leakers' reports corroborate each other — if true, Apple Watch will take another step from fitness tracker toward personal health hub. Worth watching.

Confirmed

• Leak account testingcatalog discovered a new feature called Health Age, which compares personal health metrics against peer-group standards and uses AI to generate health insights; screenshots show the feature centers on AI-generated health advice
• testingcatalog also reports a Health & Fitness update bringing Apple Intelligence-driven AI health insights, launching alongside the S12 chip version and Ultra 4 model
• LinusEkenstam detailed the health upgrades: a Readiness score updated each morning and adjusted dynamically throughout the day, paired with AI-driven daily personalized guidance; new Health Age and Longevity tabs, along with his own data
• LinusEkenstam summarized sensor upgrades for Apple Watch 12 and Ultra 4: a brand-new Health Sensing System, larger ECG electrodes and green LEDs for more accurate heart-rate measurement; heart-rate sampling frequency increased to 60x the previous rate; HRV (heart rate variability) measured every 5 minutes

Not yet confirmed

• All of the above comes from leak accounts and personal compilations; Apple has not made any official announcement, and release timing, feature details, and hardware specs remain unverified

Why it matters

• If the leaks hold, AI-generated health insights plus high-frequency heart-rate sampling (60x sampling rate, HRV every 5 minutes) would significantly boost Apple Watch's health monitoring capability and further cement its position in the personal health management market
• Health Age and the Longevity tab make "longevity" an explicit selling point, potentially setting a new product direction for wearable health features
