Levels

Everything Is Free

All three levels of the Hildor Age Rank™ are available at zero cost. No credit card. No trial period. No hidden fees.

Why free?

We are building The Age Leaderboard. The network only works when people join it. Barriers slow adoption. So we removed them all.

Wearable Data
Connect your Oura Ring: your Level 2 score is recomputed every morning from your real sleep, heart-rate, activity and readiness data, on a 7-day rolling average. Any other wearable: enter your metrics manually.
A score you type can only go up. A score your ring writes can go down. That is the point. A connected score can go down as well as up; it never drops below your Level 1 score.
