# Apple advances health and fitness capabilities using Apple Intelligence and the most accurate heart rate sensing in a wearable

The all-new Apple Watch Health Sensing System enables a new readiness score and higher-frequency HRV, and a redesigned Health app offers users intelligent and actionable insights


Apple Watch and iPhone deliver powerful and intelligent health and fitness insights.

CUPERTINO, CALIFORNIA Apple today announced its most advanced [health](https://www.apple.com/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.

“At Apple, we believe technology can empower everyone with actionable, science-based insights built with privacy at the core. By combining breakthrough sensing on Apple Watch with Apple Intelligence in the Health app, we’re able to translate complex biometric data into clear guidance for users,” said Sumbul Desai, M.D., Apple’s vice president of Health and Fitness. “This both helps people navigate their day-to-day routines with confidence and connects those moments with deeper context around their longevity, building a strong foundation for a healthier future.”

## **The New Health Sensing System on Apple Watch**

The new Health Sensing System on Apple Watch Series 12 and Apple Watch Ultra 4 features new optical and electrical heart sensors, enabling higher-frequency heart rate and heart rate variability (HRV) measurements, a new readiness score, a more comprehensive Vitals overview with the addition of HRV, and an updated Heart Rate app.

Accuracy of health data is critical to providing meaningful insights. A scientifically rigorous study on a population of over 1,000 participants with representation across demographic groups compared the new heart rate sensing accuracy on Apple Watch against leading wearables, and resulted in Apple Watch showing the highest heart rate accuracy across devices.

With larger, power-efficient green LEDs on the optical heart sensor, Apple Watch Series 12 and Apple Watch Ultra 4 now measure heart rate every five seconds, all day long. This continuous, passive measurement delivers deeper insight into a user’s fitness and physiological state while making Exercise and Move Activity rings even more accurate. Users can view their real-time heart rate at a glance throughout their day — whether they’re recovering from a workout or dashing for the train — using the updated Heart Rate app and new watch face complications.

With the new Health Sensing System, Apple Watch Series 12 features the most accurate heart rate sensing in a wearable.

HRV, a key indicator of stress and recovery, is now measured as often as every five minutes — 24x more frequently — and available to view in a new section of the Heart Rate app. Apple Watch provides two separate variants of HRV for better understanding of a user’s health status. Recovery HRV is best to identify daily signals of stress and recovery, while overall HRV is best for insights on a user’s broader health, including cardiovascular health. Higher variability is generally associated with better overall recovery.

Overnight vitals now includes Recovery HRV analyzed against a user’s personal baseline, providing a more complete view of their health status. A new daytime vitals view lets users toggle between overnight and daytime metrics, and can potentially spot shifts in their metrics before they show up overnight.3

## **Readiness: A Daily Read on the Body’s Capacity**

Apple Watch Series 12 and Apple Watch Ultra 4 introduce readiness — a new feature that analyzes a user’s recent activity, vitals, and sleep score, and then provides a single 0-10 score each day with a clear, actionable recommendation: Recover, Pace Yourself, Ready, or Go For It. This helps a user decide how to take on their workday or tackle their training plan.


The new readiness feature analyzes activity, vitals, and sleep score to deliver a daily 0-10 score along with actionable recommendations to optimize a user’s day.

Readiness updates throughout the day as new data comes in, reflecting, for example, an intense workout or a shift in daytime vitals. Readiness clearly highlights which factors are driving the score and allows users to tap into more details. The scoring algorithm was developed using data from the Apple Heart and Movement Study, in collaboration with exercise scientists and physicians at Apple.

## **A Redesigned Health App with Apple Intelligence at Its Core**

The Health app on iPhone is a central and secure location for a user’s health and fitness information, and can uniquely provide a better understanding of their overall health. Apple Intelligence brings powerful AI capabilities into the apps and experiences users rely on every day, making them more personal and helpful than ever, and with iOS 27 and iPadOS 27, Apple Intelligence extends to the Health app. Redesigned to dynamically adapt to a user’s personal health and fitness metrics, the Health app now offers iPhone and iPad users a view of their long-term health alongside easy-to-understand insights, providing personalized guidance that can help them live a better day and healthier life. The redesigned Health app has been built to securely and privately protect a user’s data at every step.

**Insights Tab**

**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.

For example, after a user receives their annual lab results, the Health app will present a video from an expert explaining their LDL levels, what the data means, and how they can take steps to improve, if needed. Or if a user learns from their movement assessment that they need to work on their balance, the Health app will present a video from an expert explaining what they can do. They will also receive an exercise plan to help them improve their balance, with moves selected for their ability and needs.

The redesigned Health app will be available later this year, starting in U.S. English, with more languages to follow.

## **Perimenopause and Menopause Support Arrive on Cycle Tracking**

A person’s menstrual cycle is an essential indicator of overall health, and the Cycle Tracking experience is designed to support individuals across life stages, from logging their first period to receiving a retrospective ovulation estimate, and now, to supporting perimenopause and menopause. Cycle Tracking adapts as users’ health priorities change, whether that’s rooted in curiosity, daily planning, family building, or long-term wellbeing.

With iOS 27, the Health app adds support for perimenopause and menopause, as well as notifications about cycle deviations inclusive of perimenopause, to Cycle Tracking. Users will be able to log if they are in perimenopause or menopause for further customization of their Cycle Tracking experience, track their symptoms, and monitor cycles over time. Additionally, if a user logs bleeding after menopause, they will receive a notification to speak with their doctor. New educational articles are available in the Health app to help users better understand this new chapter, in addition to tips informed by clinical experts.

Additionally, many people don’t recognize they’re in perimenopause because the symptoms can start years before their last period. Now, users age 40 and over can receive a notification if a deviation in their logged cycle patterns is suggestive of perimenopause, so they can speak to their doctor about it at their next appointment.4

PRESS RELEASE

Apple advances health and fitness capabilities using Apple Intelligence and the most accurate heart rate sensing in a wearable

The all-new Apple Watch Health Sensing System enables a new readiness score and higher-frequency HRV, and a redesigned Health app offers users intelligent and actionable insights

CUPERTINO, CALIFORNIA Apple today announced its most advanced [health](https://www.apple.com/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.

“At Apple, we believe technology can empower everyone with actionable, science-based insights built with privacy at the core. By combining breakthrough sensing on Apple Watch with Apple Intelligence in the Health app, we’re able to translate complex biometric data into clear guidance for users,” said Sumbul Desai, M.D., Apple’s vice president of Health and Fitness. “This both helps people navigate their day-to-day routines with confidence and connects those moments with deeper context around their longevity, building a strong foundation for a healthier future.”

**The New Health Sensing System on Apple Watch**

The new Health Sensing System on Apple Watch Series 12 and Apple Watch Ultra 4 features new optical and electrical heart sensors, enabling higher-frequency heart rate and heart rate variability (HRV) measurements, a new readiness score, a more comprehensive Vitals overview with the addition of HRV, and an updated Heart Rate app.

Accuracy of health data is critical to providing meaningful insights. A scientifically rigorous study on a population of over 1,000 participants with representation across demographic groups compared the new heart rate sensing accuracy on Apple Watch against leading wearables, and resulted in Apple Watch showing the highest heart rate accuracy across devices.

With larger, power-efficient green LEDs on the optical heart sensor, Apple Watch Series 12 and Apple Watch Ultra 4 now measure heart rate every five seconds, all day long. This continuous, passive measurement delivers deeper insight into a user’s fitness and physiological state while making Exercise and Move Activity rings even more accurate. Users can view their real-time heart rate at a glance throughout their day — whether they’re recovering from a workout or dashing for the train — using the updated Heart Rate app and new watch face complications.

HRV, a key indicator of stress and recovery, is now measured as often as every five minutes — 24x more frequently — and available to view in a new section of the Heart Rate app. Apple Watch provides two separate variants of HRV for better understanding of a user’s health status. Recovery HRV is best to identify daily signals of stress and recovery, while overall HRV is best for insights on a user’s broader health, including cardiovascular health. Higher variability is generally associated with better overall recovery.

Overnight vitals now includes Recovery HRV analyzed against a user’s personal baseline, providing a more complete view of their health status. A new daytime vitals view lets users toggle between overnight and daytime metrics, and can potentially spot shifts in their metrics before they show up overnight.3

**Readiness: A Daily Read on the Body’s Capacity**

Apple Watch Series 12 and Apple Watch Ultra 4 introduce readiness — a new feature that analyzes a user’s recent activity, vitals, and sleep score, and then provides a single 0-10 score each day with a clear, actionable recommendation: Recover, Pace Yourself, Ready, or Go For It. This helps a user decide how to take on their workday or tackle their training plan.

Readiness updates throughout the day as new data comes in, reflecting, for example, an intense workout or a shift in daytime vitals. Readiness clearly highlights which factors are driving the score and allows users to tap into more details. The scoring algorithm was developed using data from the Apple Heart and Movement Study, in collaboration with exercise scientists and physicians at Apple.

**A Redesigned Health App with Apple Intelligence at Its Core**

The Health app on iPhone is a central and secure location for a user’s health and fitness information, and can uniquely provide a better understanding of their overall health. Apple Intelligence brings powerful AI capabilities into the apps and experiences users rely on every day, making them more personal and helpful than ever, and with iOS 27 and iPadOS 27, Apple Intelligence extends to the Health app. Redesigned to dynamically adapt to a user’s personal health and fitness metrics, the Health app now offers iPhone and iPad users a view of their long-term health alongside easy-to-understand insights, providing personalized guidance that can help them live a better day and healthier life. The redesigned Health app has been built to securely and privately protect a user’s data at every step.

**Insights Tab**

The new Insights tab surfaces timely health information with a summary that updates throughout the day across heart, sleep, readiness, fitness, vitals, and cycle tracking data. A new For You section delivers personalized recommendations and relevant articles based on a user’s data — like a suggestion to improve a wind-down routine after a stretch of late nights.

**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.
