An earring that reads your body, then gets out of the way.
No screen, no notifications, no monthly fee. Just the most accurate overnight measurements a wearable can take, turned into one clear morning.
- 01
Wear it. Forget it.
Titanium, 2.1 g, a sculpted hook in front and a clear sensor back behind the lobe. Eight days of battery so charging is a Sunday habit, not a nightly chore.
- 02
It measures while you sleep.
The earlobe is one of the best-perfused spots on the body. Overnight, the earring reads heart rate, HRV, temperature, breathing and movement every few seconds.
- 03
You wake up to a plan.
Three scores and a three-sentence brief. Push today, or rest? The app is designed to be closed within a minute.
- 04
It gets smarter about you.
Every score is relative to your own baseline. After two weeks it knows what normal looks like for you, and it tells you when you drift.
Everything your body is telling you, in one place.
Twenty-plus biometrics measured from the earlobe, distilled into three daily scores and a handful of insights you will actually use.

Plays well with the apps you already use.
