The Science Behind Merios
Merios is built on evidence-based methodology, translating complex biomarker data into actionable health insights. Our scoring system integrates clinical science, wearable technology, and personalized wellness data to give you a comprehensive understanding of your health.
Every metric matters. Every insight is backed by scientific research.
The Merios Score
Your Merios Score (0–100) is built on four equally-weighted pillars, each contributing 25% to your overall score. This balanced approach ensures no single dimension dominates your health picture.
Sleep
Sleep quality, duration, consistency, and deep sleep ratios tracked via Apple Health. Your sleep pillar reflects how well your body recovers each night.
Stress
Heart rate variability (HRV), resting heart rate, and self-reported stress levels from daily check-ins. This pillar captures your nervous system balance and recovery capacity.
Activity
Daily steps, workout frequency, active energy burned, and movement consistency from Apple Health. Your activity pillar rewards consistency over intensity.
Biomarkers
130+ blood biomarkers analyzed across 11 health systems. Each marker is scored against clinical reference ranges and weighted by medical significance for your profile.
Beyond the Score
Your Biological Age
Merios calculates your biological age using the PhenoAge algorithm, a clinically validated model based on 9 key blood biomarkers. Your biological age reflects how fast your body is actually aging—independent of your calendar age—and is further refined by HealthKit lifestyle data and supplementary biomarkers.
