Precision That Adapts To You
Highly precise sensors read your body 24/7 — delivering personal health data, day and night.
99% Heart Rate Accuracy
6 precision sensors working continuously. Heart rate, SpO2, HRV, skin temperature, sleep staging, and stress detection — all from your finger.
Everyday Health Sensing
The answer to "how did you sleep last night?" Your score is built from total sleep, heart rate variability, nighttime movement, and sleep regularity.
Every step, workout, and walk to your car counted. See how your daily movement adds up and where you can push a little further.
A daily signal built from your sleep, recovery, and activity balance — so you know whether to push hard or take it easy today.
Passive stress detection throughout the day, with recovery time tracking so you can see how quickly your body bounces back.
Continuous heart rate and HRV monitoring, day and night — built on the same precision sensors trusted for clinical-grade accuracy.
What People Are Saying
The numbers are nice. The trust is better.
I stopped checking my phone first thing in the morning. The ring already tells me everything I need to know before I'm even out of bed.
I've tried two other smart rings before this. This is the first one that actually feels like a ring — not a gadget I'm wearing.
My sleep score finally matches how I actually feel. That accuracy alone was worth the switch.
I wear it to client meetings, to the gym, to bed. It's the only piece of tech I own that I never have to think about taking off.
The battery life is the real difference. I charge it once and forget about it for almost a week.
It reads like jewelry on my hand, not a device. People ask where I got the ring before they ask what it does.
