You train. You track. But sometimes progress stalls and the reason isn’t obvious. Biometryx brings your health and performance metrics together to estimate your Biological Age and highlight the systems that may need attention. Instead of looking at dozens of disconnected metrics, Biometryx helps you see the bigger picture. How Biometryx Works Biometryx analyzes signals from multiple health systems: • Cardio fitness • Metabolic health • Muscle performance • Recovery & sleep Using metrics such as: • VO₂ Max • Resting heart rate • HRV • Sleep duration and deep sleep • Strength performance • Body measurements • Blood biomarkers Each system is analyzed individually and then combined into an overall Biological Age estimate so you can understand where you currently stand. Your Health, Broken Down Clearly Biometryx helps you identify which systems may be holding you back. You’ll see: • Your Biological Age estimate • Cardio Age based on endurance and heart metrics • Metabolic Age based on body composition and biomarkers • Muscle Age based on strength performance • Recovery Score based on sleep and recovery signals Turn Insights Into Action Biometryx analyzes your metrics and provides AI-generated insights designed to help you better understand your data. These insights highlight patterns across your metrics and suggest areas that may deserve attention in your training, recovery, or lifestyle habits. Track Your Progress Health improvements take time. Biometryx helps you monitor your progress with: • Trends across key health indicators • Changes in your Biological Age estimate • Performance and recovery patterns over time Subscription Information: • Biometryx Pro Monthly or Annual. • Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. • Payment will be charged to your iTunes Account at confirmation of purchase. • You can manage subscriptions and turn off auto-renewal in your Account Settings after purchase. • Terms of Use: https://biometryxapp.com/terms • Privacy Policy: https://biometryxapp.com/privacy

Lifetimer turns a blood panel you already have into a calm, transparent biological-age estimate—shown as a range, never false precision. AN HONEST ESTIMATE • Uses the published Levine 2018 PhenoAge equation. • Shows a biological-age range, coverage level, and exactly how many required markers you supplied. • Builds each estimate from one dated pathology panel—never a synthetic mix of different lab dates. • Suppresses the estimate below seven of nine required markers. • Explains disclosed population-reference assumptions for partial panels. YOUR DATA STAYS YOURS • Biomarkers and wellness signals remain on your device. • No account is required. • No ads, tracking, or third-party analytics. • Export your readings as CSV or erase local data at any time. FREE, FOR REAL • Unlimited manual biomarker entry. • Your current coverage-labelled PhenoAge estimate. • Weekly HRV, resting-heart-rate, VO₂ max, and sleep context from read-only Apple Health access. • Full methodology and citations. GO DEEPER WITH PRO • Signed per-marker model contributions with population reference ranges. • On-device, evidence-graded lifestyle ideas with citations and careful association language. • Longitudinal estimate trajectory and full history. • On-device lab PDF/photo scan with confirm-before-save editing. • A coverage-labelled provider summary for a clinician conversation. Lifetimer is a consumer wellness estimator and educational tracking aid, not a medical device. It does not provide a diagnosis, prognosis, treatment, or medical advice. Discuss lab results, supplements, and health decisions with a qualified clinician. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period.
