What it measures
Five readings. One picture of you.
The band captures, without you doing anything, what happens while you sleep, move, train and rest. Then it organizes all of it into a clear picture of how you are today.
01
Sleep
Stages, interruptions and how long it takes you to fall asleep. The foundation of everything else.
02
Activity
Real movement throughout the day, not just the part you call a workout.
03
Heart
Continuous rate, resting pulse and variability, measured every second.
04
Recovery
How much you have replenished of what you spent. It decides your next day.
05
Insight
All of the above, translated into one concrete decision every morning, alongside your biological age and pace of aging.
The system
JUVENAI is not just a band.
It is a complete personal-technology experience: the object you wear, the software that interprets it and a history that becomes more useful every week. The band feeds the JuvenAI platform, the same one that analyzes blood biomarkers, computes your biological age and builds your action plan.
Band
Measures without you doing anything
App
Organizes and compares against your own history

The technology
Your body generates data. JUVENAI understands it.
Measuring is the easy part. The hard part is deciding what it means. Between the sensor and your screen, three things happen.
01
Data
The sensors take more than 200 readings per minute: pulse, variability, oxygen, temperature and movement.
02
Analysis
The model compares those readings against your own history. Not an average: you, one week ago.
03
Insight
The result is a sentence, not a chart: today is a day to train hard, or today is a day to slow down.
