More data means a more precise score. Choose your level. All three are free.
Each level adds data. Each level raises the bar of proof. Each level unlocks a higher maximum score on the Hildor Age Rank™.
A 2-minute lifestyle interview covers the nine factors with the strongest evidence-based link to biological aging: exercise frequency, sleep quality, diet, body composition, smoking status, alcohol consumption, stress levels, chronic conditions, and family longevity. Your answers are processed through the Hildor Age Rank™ algorithm, adjusted for your age, geographic region, and urban environment, to produce an estimated biological age and a score from 0 to 400.
Level 2 incorporates biometric data from your wearable device. With an Oura Ring you connect once and Hildor reads your sleep, resting heart rate, heart rate variability, readiness, activity and VO2 max every morning; your score is recomputed on a 7-day rolling average without you typing anything. With any other wearable (Apple Watch, Garmin, WHOOP, Polar) you enter the same metrics manually. Objective measurements replace self-reported estimates, and the maximum scoring range increases to 600.
A score you type can only go up. A score your ring writes can go down. That is the point. A connected score can go down as well as up. It never drops below your Level 1 score, and it freezes, rather than falling, if your ring stops sending data for 14 days.
Level 3 is the most detailed level open today. You enter six standard blood biomarkers from any routine blood panel: HbA1c (glycated hemoglobin), fasting glucose, triglycerides, HDL cholesterol, total cholesterol, and hs-CRP (high-sensitivity C-reactive protein). These markers cover metabolic health, cardiovascular risk, and systemic inflammation — the three pillars of biological aging. Combined with your lifestyle data and wearable metrics, the algorithm produces a score from 0 to 800, the highest ceiling open today.
The leaderboard resets after every data is inserted. Your score is only as good as your latest data.

Your Hildor Age Rank™ is calculated based on your current data level.

All members compete on the same leaderboard regardless of their data level. A Level 1 user with a score of 350 ranks alongside a Level 3 user with a score of 720. The difference is proof: higher levels unlock higher possible scores, which means more data gives you a competitive edge.
The leaderboard ranks members across multiple categories so you can compete against the people who matter most to you:
