Drift: Longevity Health Coach

Drift is a longevity coach for iPhone and Apple Watch. It reads your Apple Health data, compares every day with your own baseline, and shows what your sleep, training and recovery mean for how long and how well you'll live — and what to do today.

WHAT DRIFT GIVES YOU

• Drift Score: one daily number that shows whether your sleep, activity, heart health, mobility and recovery are on course or drifting from your normal rhythm.
• Longevity Score and biological age: eight biomarkers — VO2 max, HRV, resting heart rate, sleep, daily steps, exercise, heart rate recovery and walking speed — scored against age-adjusted thresholds from peer-reviewed research (JAMA, NEJM, JACC, WHO), with the citations in the app. Drift also shows your pace of aging.
• Fitness Score, strain and form: a 0–100 score built from five sub-scores (Load, Intensity, Readiness, Variance, Strength), a daily strain target, and your heart-rate zones mapped to the 80/20 model.
• Sleep: a personal bedtime window, an optional 14-night regularity challenge and bedtime alarm, and jet-lag handling when you cross time zones.
• 27 patterns, from Sleep Debt and Overtraining to Possible Illness and Resting HR Creep, plus good ones like an HRV rebound. Each shows the signals behind it.
• Sun exposure: a personal daily UV limit for your skin type.

HOW IS DRIFT DIFFERENT?

Drift measures you against your own rolling baseline, not a population average, so it notices a change sooner. Every score explains itself and points back to the data that drove it.

DOES IT WORK WITHOUT AN APPLE WATCH?

Yes. Drift works with Apple Watch and with 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

See how you are today and what to do right now. The watch app reads its own Health data for live heart rate and steps, last night's sleep stages and this morning's recovery, and counts today's strain from the workouts it records, even before your iPhone syncs. Seven complications keep your score, sleep, strain and UV index one glance away. Requires watchOS 26.

ASK DRIFT

Ask why your score moved, what changed this week or what a biomarker means. Apple Intelligence answers from your own data, on your device.

IS MY HEALTH DATA PRIVATE?

Yes. All analysis runs on your iPhone and Apple Watch, including anomaly detection, score forecasting and Apple Intelligence. No health data is ever transmitted, stored remotely or shared. No account, no analytics, no tracking.

WHAT DRIFT READS

60+ Apple Health data types: activity, workouts, sleep stages, heart rate and HRV, VO2 max, walking speed and gait, running form, daylight, environmental noise, cold water sessions and more.
