On Your Finger

The health tracker shrank to a band of titanium on one finger — no screen, no buzz, just a morning report on sleep, readiness and heart rhythms gathered while its wearer ignored it.

Inside this volume

Fifty first-person accounts cover life with a smart ring: sleep debt made visible and negotiated with, illness flagged by overnight temperature before symptoms arrived, resting heart rate as a training referee, and cycle tracking that earned trust or didn't. Writers include the data-anxious who had to take it off, subscription-fee grumbling, batteries and sizing, accuracy face-offs against watches, and the quiet converts who kept the ring precisely because it asks for no attention.

Who it's for

For anyone choosing between ring and watch, drowning in readiness scores, or curious what a year of passive data actually changes.
