August 24, 2026
Every sleep stage, one tap away. • Tap any sleep stage — Deep, REM, Core, or Awake — for a full detail view: last night, your 14-night history, your 30-night average, and what that stage does for your body. • Fairer deep-sleep scoring: Drift now scores deep sleep against what wearables actually measure and your own range — consistent nights get the credit they deserve. • Sleep is now always shown in hours and minutes across the whole app — 7h 54m, never 7.9. • Two-week sleep trends are now tappable — and overnight HRV and resting heart rate join them, each opening a full history view.

FAQ
What is Drift's daily health score?
Drift calculates a personalized score each morning by analyzing your sleep, activity, heart health, mobility, and recovery against your personal baseline. This score indicates whether your health metrics are aligned with your body's natural rhythm or drifting away from it.
How does Drift ensure data privacy?
All analysis and scoring are performed entirely on your device using Apple's frameworks. No health data is transmitted, stored remotely, or shared with any third parties, ensuring complete privacy without requiring an account or analytics.
What scientific research is Drift based on?
Drift's thresholds are grounded in peer-reviewed research from journals like JAMA, NEJM, The Lancet, and JACC. It scores eight key biomarkers against age-adjusted population norms from these studies.
How does Drift's Fitness tab work?
The Fitness tab provides a 0-100 score that blends training load metrics over the last 14 days. It includes sub-scores for Load, Intensity, Readiness, and Variance, linking back to specific workouts and mapping your time-in-zone to established endurance research models.
What devices are compatible with Drift?
Drift works with any device that writes data to Apple Health, including smart rings, fitness bands, and GPS watches. iPhone-only users without a wearable can still receive a partial score based on activity and step data.
