Your biological age is not your birthday. JuvenAI reads the signals your body is already producing — blood biomarkers, sleep, heart, activity and recovery — and turns them into one clear number you can act on.
KNOW YOUR BIOLOGICAL AGE
Upload a lab report and JuvenAI extracts your biomarkers, lets you review and correct every value, then estimates your biological age with PhenoAge, a published scientific algorithm. Watch it respond as your habits change.
YOUR WEARABLE, DECODED
Connect Apple Health and JuvenAI builds a recovery-centric dashboard from your sleep, heart rate, HRV and activity. Read-only by design: JuvenAI never writes to Apple Health.
A COACH THAT WORKS IN CYCLES
Every 14 days, choose a small set of focus actions. JuvenAI tracks them objectively and scores your cycle, so the next one starts smarter.
LOG MEALS IN SECONDS
Photograph your plate or describe it out loud. AI-powered nutrition analysis turns it into calories and macros — no tedious database searching.
CELEBRATE REAL WINS
A community built around measurable wins, not selfies. Follow friends, join teams, and keep each other consistent.
PRIVATE BY DESIGN
Your health data belongs to you. It is stored in your own account, protected by row-level security, never sold, and never used for advertising.
Available in English and Spanish.
JuvenAI is rolling out gradually.
