Nothing measures the ten years before something goes wrong.
You are checked once a year, and the checks look for damage that has already happened. Everything in between — worse sleep, shorter temper, less left in the evening — you feel and nobody records. That gap is the whole reason this exists.
A band you never take off, and one number in the morning.
Ten signals, read all night
Sleep, heart-rate variability, calm, oxygen, temperature and five more. Ordinary alone. Read together and without gaps, they become a number that means something.
One figure, not a dashboard
Up, down, or the same. Tap it and you see what moved it. No screen on the band, charges in minutes — so it never has to come off.
It does not diagnose or treat anything. It makes a pattern visible, and what you do with it is yours.


The band is free. You pay to switch it on.
The band ships before any payment is taken. Activation is charged after it arrives.
It only works if you never take it off. That is the whole catch, and there is no second one.
The index is calculated from continuous readings. With the band off there is no input, so no value is produced for those days. Most people who abandon a wearable do so in the second week.

Take it, wear it a week, then decide.
