Wake up to the numbers from the whole night, not a guess. This slim metal ring tracks heart rate, blood oxygen, blood pressure and sleep from an optical window on the inner band, and it wears like a plain ring all day.
Wear-all-day health tracking in a slim, everyday ring: heart rate, blood oxygen, blood pressure and sleep monitoring
- bulky wrist wearables
- tracking health without a watch face
- need to monitor sleep and vitals discreetly
Health tracking you forget is on your finger
Bulky watch faces buzz and distract. This slim ring logs heart rate, blood oxygen and sleep quietly, from workout to overnight rest.
Four vitals, one slim ring on your finger

Heart rate that runs quietly
An inner optical window reads pulse from the finger all day. There is no face to glance at and no strap to tighten, so the reading happens while you work, drive or lift.

Sleep logged overnight
The ring records sleep and heart rate while you rest. Your morning summary covers the whole night, not the few hours you remembered to check a screen.

Metal build, everyday finish
The polished outer shell and brushed steel inner band look refined at a desk and in the gym. Pearl white and gloss black versions both hold a clean, metal edge.
Optical sensing from the inside of your finger
- 1Size it snug
Choose a ring that sits flat without pinching and stays put when you make a fist. Movement is the most common reason readings drift.
- 2Turn the sensor inward
Keep the inner band and its sensor window against the underside of the finger. The light has to pass through steady skin contact to read pulse well.
- 3Pair the app
Connect the ring to the companion app, then wear it for a full day so the heart rate baseline starts to build.
- 4Top up on the contacts
Set the ring on the charger so its contacts meet the metal pads on the inner band. Charge during the day so it has power for overnight sleep tracking.
The watch you stopped wearing is still the problem
The watch you stopped wearing
A wrist watch is large, has a screen that lights up at the wrong moments, and clashes with a work shirt or a bedside table. Most people leave it in a drawer within weeks, and the health data leaves with it.
What the data you're missing could show
Poor sleep and a pulse that spikes for no clear reason can run for months before anyone notices. Without a steady record, those patterns stay hidden until they turn into a real problem.
A ring that stays out of sight
This ring reads heart rate, blood oxygen, blood pressure and sleep from an optical window on the inner band. It sits on the finger, where nobody sees a screen, and it keeps working through the day and the night.
What to expect over time
- First usePair and get a fit
Pair the ring with the app and find a snug fit so the sensor sits flat against skin. Readings improve once the fit is right.
- Week 1Build a first baseline
Wear it daily and overnight to see resting heart rate and sleep patterns emerge. Early trends are rough until several nights of data accumulate.
- 30 daysSpot personal patterns
A month of data shows how workouts, stress and sleep habits line up with your vitals. Discuss any unusual readings with a doctor.

Questions and answers
The ring estimates blood pressure as a wellness trend. It is not a clinical cuff. Use the numbers to spot patterns and bring any concern to your doctor, who can confirm with a medical-grade device.
Pick a size that sits snug without pinching and stays put when you move your hand. The sensor window on the inner band needs flat skin contact. A loose ring lets light leak in and weakens the readings.
The ring charges through the metal contacts on its inner band, so it sits on a matching charger instead of a cable. Top it up during the day so it has power for overnight sleep tracking.
Yes. The ring records sleep and heart rate while you rest, so the morning summary covers the whole night rather than the hours you remembered to check.
The polished metal shell and brushed steel band cost more than plastic bands, but you keep a ring on your hand all day. Spread the price across the nights you actually wear it and the cost per day drops quickly, especially compared with a watch left in a drawer.
A smartwatch sits on the wrist with a screen face to check. This ring sits on the finger with no face, so it stays out of sight under a cuff, at a keyboard or in bed.
