Gradual Healthspan & Longevity

Gradual calculates your biological age from 5 health dimensions, then gives you the tools to improve. Personalized insights based on your labs, activity and biomarkers.

Gradual calculates your biological age from five science-backed health dimensions then gives you the tools to improve it. Learn from actionable insights based on your individual biomarkers, vitals, workouts and longevity insights, all in one place.

YOUR BIOLOGICAL AGE (GRADUAL AGE) See beyond the calendar. Your Gradual Age is a composite biological age built from five pillars: cardiorespiratory fitness, autonomic health, sleep quality, vascular function, and PhenoAge blood biomarkers. Compare each dimension to your chronological age, track your trend over time, and share your results with your doctor.

DAILY READINESS SCORE Know when to push and when to recover. Your Readiness Score combines HRV, resting heart rate, sleep, training strain, and mood — calibrated to your personal baselines, not population averages.

AI-POWERED LAB ANALYTICS Upload a PDF from any lab provider and Gradual extracts the results automatically. Track 40+ blood biomarkers across cholesterol, glucose, hormones, vitamins, inflammation, and more. Every optimal range is backed by peer-reviewed citations so you can take control of your healthspan.

HABITS THAT COMPOUND Small inputs, big outcomes. Build daily routines around supplements, fitness goals, mindfulness, and sleep targets. Track streaks and monitor weekly consistency with zero friction and no manual entry.

CONNECT YOUR DEVICES Sync with Apple Health and Strava. Sleep, HRV, resting heart rate, VO2 max, training load, and more flow in automatically — no extra wearable required.

AI HEALTH INSIGHTS Get context-aware analysis across your habits, vitals, and labs. Tap any insight to ask follow-up questions. Understand what's driving your biological age and what you can do to reverse aging trends. Rule-based insights are always free.
