Metric: Health & Longevity

Metric brings the health data you already collect into one place—and helps you understand what to do with it.

Connect supported Apple Health and Apple Watch data across sleep, HRV, resting heart rate, workouts, nutrition, stress, blood pressure, body composition, cardio fitness, and daily activity. Metric organizes those signals into readable trends and biological-age estimates, while a separate workout-load model provides readiness and strain context. Explore supported data through questions you ask Cortex AI.

ONE HEALTH DASHBOARD

See the signals that matter without jumping between apps. Review recent values, target-range context, long-term charts, and related measurements from a single home for your health data.

BIOLOGICAL AGE AND AGING RATE

Explore an estimate built from supported cardio-fitness, cardiovascular, body-composition, movement, and sleep signals. See which available inputs are pulling the estimate younger or older, how much data is contributing, and how the trend changes over time.

READINESS, STRAIN, AND WORKOUTS

Understand short-term training load in relation to your longer-term baseline. Record workouts from iPhone or Apple Watch, follow heart-rate zones, review routes and splits, and keep recent effort connected to recovery context.

SLEEP AND RECOVERY

Review sleep duration, stages, consistency, Sleep Score, overnight heart rate, respiratory rate, and related trends together. Metric makes it easier to distinguish one unusual night from a pattern worth watching.

NUTRITION IN CONTEXT

Log meals with AI-assisted capture or manual entry. Follow calories, macros, protein, sodium, caffeine, and other details alongside the sleep, activity, stress, and cardiovascular signals they may help you interpret.

ASK CORTEX

Ask questions about supported data in Metric. Compare health-metric periods, review recorded workouts or sleep totals, explore nutrition, or examine biological-age contributors without searching through every chart yourself.

HEART AND BODY METRICS

Track resting heart rate, HRV, VO₂ Max, blood pressure, oxygen saturation, body mass, body fat, lean mass, and other supported Apple Health measurements with clear units and historical context.

SOCIAL FITNESS

Share workouts and achievements, follow friends, celebrate progress, and choose when live workout visibility is appropriate for you.

PRIVACY CONTROLS

You choose which supported Apple Health categories Metric can read or write through Apple’s permission controls. Metric explains missing inputs and provides settings for managing connected features.
