Drift: Longevity Health Coach

Drift shows your biological age and longevity score from the Apple Watch and Apple Health data you already have, and what to work on today. It runs on your iPhone with no account, and the daily Drift Score, Longevity Score and Fitness Score are free. WHAT IS MY BIOLOGICAL AGE? Drift estimates it from six measures in Apple Health: VO2 max, resting heart rate, HRV, sleep, walking speed and exercise. It shows which way each one pushes your age, and your pace of aging over time. It is an estimate from your own data, not a clinical or epigenetic test. WHAT DRIFT GIVES YOU • Drift Score: one daily number that compares today with your own baseline for the same weekday, across sleep, activity, heart, mobility and recovery. • Longevity Score: eight biomarkers (VO2 max, HRV, resting heart rate, sleep, steps, exercise, heart rate recovery, walking speed) graded against age-adjusted thresholds from published research and guidelines (JAMA, NEJM, JACC, WHO), with the sources in the app. • Fitness Score, strain and form: five parts (Load, Intensity, Readiness, Variance, Strength), a daily strain target and your heart-rate zones. • Sleep: a personal bedtime window, a 14-night regularity challenge, a wind-down reminder and jet-lag help. • 27 patterns, such as Sleep Debt, Overtraining and Possible Illness, plus good ones like an HRV rebound, each with the signals behind it. • Sun exposure: a daily UV limit for your skin type. HOW IS DRIFT DIFFERENT? It compares you with your own baseline, not a population average, so it notices change sooner, and every score shows the data behind it. No extra strap or ring: it uses the watch you already wear. DOES IT WORK WITHOUT AN APPLE WATCH? Yes. Drift reads any ring, band or watch that writes to Apple Health. With an iPhone alone you get a partial score from steps and activity. DRIFT ON APPLE WATCH The watch app reads its own Health data for heart rate, steps, sleep and recovery, and works out today's strain from your workouts before your iPhone syncs. See today's workouts with the minutes in each heart-rate zone. Seven complications show your score, sleep, strain and UV. ASK DRIFT Ask why your score moved, what changed this week or what a biomarker means. Answers come from your own data, using Apple Intelligence on supported iPhones where it is turned on. Scores work without it. IS DRIFT FREE? Yes, to start. Free: the daily Drift Score with today's insight, the Longevity Score, the Fitness Score, the Apple Watch app, widgets and notifications. The subscription opens the detail behind them: your biological age number (the free version shows which way it points), the eight biomarkers, the category breakdown, the five Fitness parts and every detail view.
