Stay younger, longer.

Your Apple Watch already tracks your body. Now turn that data into a clearer picture of how you’re aging—and what you can do to help stay younger for longer.

The app connects with Apple Health and Apple Watch to bring together your sleep, nutrition, workouts, heart trends, body composition, cycle, recovery and more.

At the center is your Health Age: an estimate based on your calculated Aging Speed and more than 50 health metrics.

Your Aging Speed model is informed by insights from 50+ longevity and health research papers, helping translate everyday health data into one simple question:

Are your current habits helping you stay younger—or aging you faster?

Your Health Age

See an estimated age for your current health and track how it changes over time.

Your Health Age is influenced by areas including:

• Sleep and recovery
• Nutrition
• Strength and fitness
• Heart health
• Activity
• Body composition
• Metabolic health
• Lifestyle trends

Instead of obsessing over individual scores, see how everything works together.

Your Apple Watch, Reimagined

Your Apple Watch collects an incredible amount of information about your body.

The app turns that data into meaningful trends so you can understand how your sleep, heart, movement, workouts and recovery may be connected to how well you’re aging.

See what’s improving, what needs attention and which habits may make the biggest difference.

Food Logging in Seconds

Eating well shouldn’t require spending your life logging meals.

Our ultra-fast food logging workflow lets you record food in just a few seconds.

The app analyzes your nutritional patterns and recommends healthy-aging recipes based on what your diet may currently be missing, making it easier to decide what to eat next.

Track nutrients, spot gaps and build a diet designed around helping you feel and look your best for longer.

Get Stronger With Age

Automatically import supported workouts from Apple Watch or track your gym sessions directly.

Log exercises, weights and reps to follow:

• Strength progression
• Training volume
• Workout consistency
• Personal gym trends

Because staying young isn’t only about how you look—it’s about staying strong, capable and energetic.
