Vital
Vital Ring · Series 4

Vital is a 4-gram titanium ring that reads your pulse 100 times a second through the night and your recovery through the day. No screen to check, no wrist to charge every evening — just one honest answer each morning: how hard should you go today?

Inside the band

Six ways to read you.Nothing on your wrist.

The finger sits closer to the artery and moves less than the wrist, so the signal is cleaner. We fit six sensing systems into a band you forget you're wearing — and let them work without ever asking you to press start.

Heart rate, straight off the artery

Green and infrared LEDs read your pulse from the digital artery in your finger, capturing resting heart rate and heart-rate variability all night with an accuracy that lands within ±3 bpm of a 12-lead ECG.

Sleep stages, told straight

Vital scores light, deep, and REM minute by minute, then reports the night you actually had — including the 1:40 AM wake-up you won't remember. No inflated numbers to keep your streak alive.

Skin temperature to a hundredth of a degree

A medical-grade thermistor tracks your nightly temperature against your own baseline, surfacing the small overnight rise that often appears a day or two before a cold or a hard cycle does.

Blood oxygen, awake or asleep

Red-light SpO2 sensing watches for the dips that flag disrupted breathing in your sleep or thinner air at altitude, so a rough night or a high trail shows up in the data instead of just your legs.

Respiratory rate, all night long

By fusing the optical pulse signal with subtle chest movement, Vital tracks breaths per minute while you sleep — a quiet early signal of stress, illness, and how deeply you're actually resting.

Motion and live workouts

A 3-axis accelerometer auto-detects more than 40 activities and turns a run, a lift, or a yoga flow into real heart-rate zones — no button to press, no session you forgot to log.

Engineered to disappear

Aerospace titanium.Built for ten yearsof mornings.

Most wearables compete for your attention. Vital is built to vanish — on your finger in a meeting, in the ocean, and in deep sleep — and to keep working long after this year's wrist tracker is dead in a drawer.

Grade-5 titanium shell

Aerospace-grade titanium with a scratch-resistant PVD coating shrugs off keys, kettlebells, and saltwater. It's the same alloy used in surgical implants — hypoallergenic against skin, worn day and night.

Waterproof to 100 meters

Swim, shower, surf, and dive without a second thought. Vital keeps reading your heart rate underwater, so a morning lap counts toward your day exactly as much as an evening run.

7-day battery, 80-minute top-up

A full week between charges, then back to 100% on its magnetic dock in under ninety minutes. Charge it while you shower and your sleep tracking never opens a gap.

Your data stays yours

Health data is encrypted end to end and never sold, rented, or handed to advertisers. No subscription is required to keep your own history, and one tap deletes all of it for good.

A day on Vital

One ring, from lights-out to last set.

You never open an app to make Vital work. It reads the day as you live it and meets you with the one insight that matters at the moment it matters — not a wall of charts to decode.

10:45 PM

The wind-down

A bedtime window appears, set by your real sleep debt and today's recovery rather than a fixed alarm. Vital nudges you toward the hour your body is actually ready to sleep.

2:00 AM

Deep-sleep capture

While you're out cold, the ring logs heart rate, HRV, breathing, temperature, and oxygen minute by minute — quietly building the picture you'll read over coffee.

7:00 AM

The morning read

One number greets you: your Readiness Score, with a plain-English reason. Slept hot and short? Vital tells you to ease off before your body forces the issue.

12:30 PM

Train in the right zone

Start a workout and Vital auto-detects it, holding you in the heart-rate zone that fits today's recovery — push on a primed day, hold the line on a fragile one.

4:00 PM

Afternoon load check

A live stress curve shows how the day is taxing you, with a two-minute guided breath offered at the exact moment your heart rate says you need one.

9:30 PM

Tomorrow, pre-loaded

Vital projects tomorrow's readiness from how today actually went, so you plan the next morning before your head hits the pillow.

From the people wearing it

The first tracker people don't take off.

I'd given up on wearables — the wrist ones died in two days and nagged me the whole time. Vital just sits there for a week and tells me, plainly, when I've earned a hard session and when I haven't. My resting heart rate is down eleven points since spring.

Marathoner, 18 months on Vital

It flagged a temperature rise two days before I tested positive for the flu. I pulled out of a brutal training block early and recovered in half my usual time. That one save paid for the ring.

As a sleep researcher I'm allergic to gadgets that flatter you. Vital is the rare consumer device that shows me my real fragmented nights instead of a pretty number. Its HRV lines up with the lab equipment on my bench.

The questions we get before you buy.

Do I have to pay a subscription to use it?

No. The ring works on its own — sleep stages, resting heart rate, and activity — forever, with no membership. The $8/mo membership unlocks the daily Readiness Score, deeper trends, illness alerts, and guidance, but your core data is always free and always yours.

How do I get the right ring size?

Every order ships with a free plastic sizing kit first. You wear the sample sizes for a day or two — fingers swell, so fit genuinely matters — and only then do we make your titanium ring. If the fit is off, we resize it free within 30 days.

How accurate is it, really?

Vital reads your pulse from the digital artery in your finger, which is closer to the source and steadier than the wrist. In our testing, resting heart rate lands within ±3 bpm of a 12-lead ECG and overnight HRV tracks closely with lab polysomnography. It's a wellness device, not a diagnostic one — built to be honest, not flattering.

Will it survive my life?

It's grade-5 aerospace titanium, waterproof to 100 meters, and rated for swimming, lifting, showering, and diving. The battery lasts about seven days and recharges fully in under ninety minutes on its magnetic dock.

Can Vital diagnose a medical condition?

No. Vital surfaces patterns in your sleep, heart rate, breathing, and temperature and can flag when something looks off, but it does not diagnose illness or replace a doctor. If a trend worries you, bring your data to a healthcare professional — exporting it takes one tap.

What happens to my health data?

It's encrypted end to end, stored against your account alone, and never sold or shared with advertisers. You can export your full history any time, and deleting your account erases your data for good — not into some archive.

Stop guessing how you slept.

Order your Vital ring today with a free sizing kit and a 30-day membership trial. Give it a week, and you'll train by what your body says — not by what your calendar planned.
