How old is your body, really?

Your functional age is how old your body actually feels on the inside — not the number printed on your ID. The sensor reads it every morning in 3 minutes, so you can tell whether what you're doing is actually working.

FUNCTIONAL AGE

How it works

1
3 minutes. Every morning.
In 3 minutes, the sensor reads the state of your autonomic nervous system — the most reliable signal of your functional age.
2
Spectral analysis. 30 years of research.
From each reading, the sensor analyzes 60+ HRV parameters — including stress and recovery.

HRV is backed by thousands of peer-reviewed studies as a proven marker of biological age.
3
See how you stack up against your peers
Tracking your functional age shows you exactly how your body compares to others your age — so you can adjust your lifestyle early, while it actually matters.

How are 20 000 people reversing their functional age?

The key is knowing what actually works — for your body.
What's actually moving your functional age?
We track your habits and connect them directly to your functional age — so you see what's pulling you younger, and what's holding you back.
The workout your body is ready for
Every morning, the sensor tells you exactly what kind of activity your body needs today — no guesswork, no generic plans.
Watch your functional age drop
Every day, see if what you're doing is actually working.
