What It Catches

It Notices, So You Don't Have To

Sleep

Light, deep and REM, plus overnight HRV and skin temperature. By morning there's a recovery score waiting, so you can plan your day around the night you actually had.

Heart Rate

Resting heart rate, HRV and SpO2, picked up in the background. No buttons, no checking in. Just trends that build while you get on with things.

Movement

Steps, calories and active minutes, counted on their own. No start button. Ring One notices when you're moving.

Stress & Recovery

Your HRV shows when the day's been a lot. A gentle nudge to breathe, and a recovery trend to look back on.

How It Works

Three Steps. That's It.

Step 1

Wear It

Slip it on and forget about it. Light, waterproof to 50m and happy to come to bed with you.

Step 2

Open the App

Your night lands over Bluetooth on its own: heart rate, sleep stages, SpO2 and activity, all in one place.

Step 3

Watch It Add Up

Over the weeks your sleep, recovery and stress trends take shape. Share them with your doctor if you like.

Fits Right In

Designed to disappear into your day, quietly tracking what matters while you live your life.

What It Does for You

Morning, noon and very late night.

Recovery

Wake up to a readiness score built from your HRV, resting heart rate and how you slept. A nudge, never a verdict.

Sleep Stages

Light, deep and REM, tracked on their own. Then see how late dinners or that second coffee show up in your night.

Stress

Your heart rate variability shows when the day's been heavy, with a gentle reminder to breathe when it might help.

Comfort

Light enough to sleep in and smooth on the inside. Gone from your mind by lunch.
