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.
