Check Biological Age

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.
