opens in new window

PRESS RELEASE September 9, 2026

CUPERTINO, CALIFORNIA Apple today announced its most advanced health and fitness experience yet, expanding what Apple Watch and iPhone can do as intelligent, science-driven tools for users’ personal wellbeing. Apple Watch Series 12 and Apple Watch Ultra 4 introduce the new Health Sensing System, enabling the most accurate heart rate sensing in a wearable, as well as a new readiness experience to give users insight into their body’s capacity to take on their day.¹ They pair with a redesigned Health app coming later this year to iPhone, which offers a holistic view of long-term health alongside new, easy-to-understand health and longevity insights powered by Apple Intelligence.² Together, these updates will give users a more complete picture of their health and fitness while keeping their personal health data private, secure, and under their control.

The New Health Sensing System on Apple Watch

• A user’s Apple Watch Series 12 shows their overnight vitals in the Vitals app, with a reading that says “Favorable.”
• A user’s Apple Watch Series 12 shows their daytime vitals in the Vitals app, with a reading that says “Typical.”

• A user’s iPhone 18 Pro shows heart health data from the Insights tab in the Health app. The summary is titled “Cardio Fitness Trending Up.”
• A user’s iPhone 18 Pro shows sleep data from the Insights tab in the Health app. At the top of the screen, a summary reads “A Good Night’s Sleep.”
• A user’s iPhone 18 Pro shows readiness data from the Insights tab in the Health app. The user has a score of 7, which means “Ready.”
• A user’s iPhone 18 Pro shows Exercise ring data from the Insights tab in the Health app. A summary reads “Your Exercise Ring Looks Good.”
• A user’s iPhone 18 Pro shows For You recommendations from the Insights tab in the Health app.

Longevity Tab
A new Longevity tab analyzes a user’s longitudinal health data for deeper insights into heart health, sleep, mental wellbeing, movement health, metabolic health, hearing, and nutrition. The tab includes Health Age, a new feature that uses Apple Watch data to show users how their metrics are tracking relative to their chronological age, informed by the best available science. The algorithm can factor in metrics from Apple Watch like VO2 max, resting heart rate, sleep, and HRV, and users can also add lab data, including A1c and LDL, to enrich the analysis.

Movement Evaluations
Mobility is a critical marker of overall function and a strong predictor of independence, chronic disease risk, and quality of life. Yet routine assessment remains largely absent from proactive health management, typically requiring a visit to an exercise physiologist or physical therapist. Now, users can take in-depth physical assessments — measuring flexibility, strength, balance, movement mechanics, and VO2 max — right at home using their iPhone camera and Apple Watch. This experience runs entirely on device; no video is ever recorded, stored, or shared. Using vision-based AI models, these assessments provide real-time audio and visual feedback, and were developed using clinician input.
