Check Biological Age is your personal longevity companion: find out how well your body is aging, then lower your biological age with a daily plan, AI coaching, and face and skin scans. DISCOVER YOUR BIOLOGICAL AGE Take our comprehensive, science-backed assessment to uncover your true biological age. Our algorithm analyzes key health indicators including lifestyle factors, physical fitness, cognitive function, and daily habits — based on the validated Frailty Index methodology. YOUR DAILY LONGEVITY PLAN Turn your result into action: pick from 14 evidence-based daily habits across movement, nutrition, sleep, mind, and protection. Check them off each day, build streaks, and watch your trend improve. CALCULATE FROM APPLE HEALTH (PREMIUM) Skip the questionnaire: connect Apple Health and get your biological age from real measurements — resting heart rate, heart rate variability, VO2 max, daily steps, sleep, walking speed, and body metrics. Read-only access, processed entirely on your device. AI LONGEVITY COACH (PREMIUM) Chat with a personal AI coach that knows your latest result, your trend, and your daily plan — and gives specific, practical guidance on sleep, nutrition, movement, stress, and skin care. AI FACE & SKIN AGE SCANS (PREMIUM) Take a selfie to estimate your apparent age, and run the dedicated skin analysis to learn how old your skin looks — with scores for hydration, texture, tone evenness, and fine lines, plus a routine to improve them. TRACK YOUR PROGRESS Every check — questionnaire, Apple Health, face scan, skin scan — is saved on your device, with a trend chart of your biological age over time. PRIVATE BY DESIGN Your answers and history are processed on your device. No account, no ads, no data selling. AI features send only the minimum needed (an anonymous result summary, your chat message, or the photo you choose) and photos are never stored. This app is for informational purposes only and does not provide medical advice, diagnosis, or treatment.

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
