Drift tracks how your daily routine compares to your personal baseline — and shows what it means for how long and how well you'll live. Every morning, Drift reads your Apple Health data to compute a personalised Drift Score: a single number that shows whether your sleep, activity, heart health, mobility, and recovery are aligned with your body's normal rhythm — or drifting away from it. ON-DEVICE AI Drift uses Apple's foundation models and on-device machine learning to analyse your health patterns — no cloud, no servers, no data leaving your phone. An isolation forest detects anomalies in your metrics. A clustering model learns your day types. A forecasting engine predicts where your score is heading. And Apple Intelligence generates personalised insights written specifically for your body and your day. LONGEVITY SCIENCE Every threshold in Drift is grounded in peer-reviewed research. Eight biomarkers — VO2 max, HRV, resting heart rate, sleep, daily steps, exercise, heart rate recovery, and walking speed — are scored against age-adjusted population norms from studies published in JAMA, NEJM, The Lancet, and JACC. This isn't guesswork — it's your data measured against decades of clinical evidence. FITNESS SCORE A new Fitness tab grades how your training is loading you. A 0–100 score blends Banister fitness, strain, and form across the last 14 days, with five sub-scores — Load, Intensity, Readiness, Variance, Strength — each pointing back to the workouts that drove them. An intensity-pattern card maps your time-in-zone to Seiler 3-zone (the 80/20 model endurance research keeps validating), and a readiness card checks eight nightly signals against your 21-day baseline. Set your Fitzpatrick skin type to personalise the daily Sun Exposure ceiling. 22 PATTERN DETECTORS Drift watches for patterns your numbers can't show on their own — Late Nights, Sleep Debt, Overtraining, Recovery Gap, Fitness Plateau, and 17 more. Each pattern includes a brief explanation and the signals Drift used to detect it. COMPLETELY PRIVATE All computation — every ML model, every score, every insight — runs entirely on your device using Apple frameworks. No health data is ever transmitted, stored remotely, or shared with any third party. No account required. No analytics. No tracking. WHAT DRIFT READS Activity, Sleep stages, Heart rate and HRV, VO2 max, Walking speed and gait, Running form, Daylight exposure, Environmental noise, Cold water sessions, and more — 60+ HealthKit metric types in total. WIDGETS Home screen and lock screen widgets show your daily Drift Score at a glance. Drift works with any device that writes to Apple Health — including popular smart rings, fitness bands, and GPS watches. The richer your Health data, the more complete your Drift Score. iPhone-only users without a wearable see a partial score based on activity and step data.
