Your body has been keeping score.
Yasu turns the readings your Apple Watch already takes into one number, the reason behind it, and a way back down.
Free to download, for iPhone and Apple Watch.
Load
One number for how loaded you are.
Load runs from 0 to 100 against your own usual. Higher means your body is working harder.

Rises
Every rise gets a name.
When Load climbs, Yasu asks what it was. One tap answers, and in time you see what keeps coming back.

Ninety seconds back down.
A paced breath on your wrist or your phone, then a receipt: your reading before and the next one after.
A 90-second Reset: breathe in and out with the ring, with no countdown.
