Product Overview

Mayissi built this ring for the hours when a watch gets in the way. The AI Insights model is our flagship for sleep and recovery: a slim silver band with the sensors, processor and battery sealed inside, and nothing on the outside but polished metal. It reads your night, your movement and your stress without a screen to check or a strap to loosen — the kind of health monitoring ring you put on in the morning and stop thinking about until you open the app.

It is aimed at people who have already tried a wrist tracker and quietly stopped wearing it: side sleepers who wake with a band pressed into their arm, anyone whose work clothes do not sit well with a sports watch, and women who would rather see their cycle and their sleep on one timeline than in two apps. It also does the one thing a bedside app cannot, which is stay on your hand all night — a sleep tracker ring has nothing to remember before bed and nothing to switch on.

- Nothing to switch on. No mode to start, no button to press and no workout to log before you begin. It records from the moment you put it on, which is unusual for a smart ring sleep tracker and is the reason the record stays complete. - Silent and screenless. Nothing lights up at 2 a.m. and nothing buzzes in a meeting. The ring simply collects; your numbers wait in the companion app until you want them. - Sensors held against the finger. The optical array sits on the inside of the band, pressed lightly against the underside of your finger by the fit itself, so a reading does not depend on how tightly you fasten anything. - One ring, one timeline. Everything the app knows comes from the same band on the same finger, so your sleep, your stress and your training share a timeline instead of living in three separate apps. - It looks like jewellery. The silver finish is plain enough to sit next to a wedding band or a dress watch and to disappear under a cuff. Nobody at the table needs to know it is measuring anything. - Made to be forgotten. A health tracking ring only tells you something useful if it is still on your finger at six in the morning; the low profile is there to make that the default rather than a discipline.

Precision Health Monitoring

Sleep staged across several nights, not one. We built this model around the question people ask when they start looking for a smart ring for sleep tracking: not how long they slept, but why eight hours can feel different on a Tuesday and a Saturday. The analysis was developed with leading universities and hospitals and works across several nights rather than a single reading. Deep, light and REM sleep are logged separately, so a run of short nights shows up as a run rather than a one-off.

What actually broke the night. Because the app can see when you woke, how long you stayed awake and what your evening looked like beforehand, it can point at likely causes of broken sleep instead of only counting the wake-ups. It also learns the hours at which you fall asleep most easily and uses them to suggest a bedtime for the evening ahead. For a sleep tracker ring, that translation is the useful part — the pattern, not the number.

Your own rhythm, described back to you. Sleep timing is personal, so the ring works out whether you lean towards mornings or evenings and shapes its suggestions around that. If you are the sort of person who has tried three apps and stuck with none of them, the appeal of a smart ring sleep tracker is that you never have to feed it anything: no diary, no tags, no nightly questionnaire.

A score you can follow, week by week. Each morning brings a daily score, with a weekly view sitting on top of it, drawn from the way your sleep, recovery and stress move together. When a pattern is worth a closer look, the app flags it so you can decide what to do about it.

Comfort, Design & Battery Life

About 2.5 g on the finger. A health monitoring ring only works if you stop noticing it, so the band was thinned and lightened until it sits close to the finger without pinching. It weighs around 2.5 g, and the sensor package inside is fused into a single module rather than stacked in layers, which is what made the slimmer profile possible.

A charge that fits your week. A full charge takes about an hour and carries you through up to seven days of normal use, or up to fifteen days on standby if you leave it off. Kept in its charging case between charges, total running time extends beyond 150 days, and the case shows its remaining power as a percentage so you are never guessing.

Finish and feel. The outside is a brushed silver-tone band with a plain rounded profile — no logo on the side, no seam to catch on a sleeve. As a wearable smart ring it is meant to be worn alongside other jewellery rather than instead of it, and the sensor side is smooth enough that a full night on the same finger does not leave a mark.

Durability & Connectivity

• 5ATM, explained. That rating is the pressure equivalent of 50 m of water — enough for the pool, the shower and a rainy commute, not intended for diving or high-pressure water sports.
• Built for a wet day. Washing up, a downpour, a lane swim: a health tracking ring that has to come off for any of them ends up with gaps in the record. Keep it on.
• Bluetooth and GPS. The ring pairs over Bluetooth and works with GPS, so a walk, a run or a ride can be pinned to where it happened as well as how long it took.
• iOS and Android. The companion app runs on both, with the same features whether you carry an iPhone or an Android phone.
• Updates over the air. New features and refinements arrive through app and firmware updates; nothing has to be sent away.
• Rated from 0 °C to 50 °C. That covers a cold morning and a hot car park. A sauna or a hot tub sits outside the range, so leave the ring in its case.
• Rinse after chlorine. Fresh water and a wipe before it goes back in the case keep the sensor window clean and the contacts dry.

Sizing & Fit

1. Measure late in the day. Fingers are at their largest then, and a size taken first thing in the morning can feel tight by evening.
2. Use the Mayissi size chart, not a jeweller's. The ring follows its own sizing standard, so a size you know from another brand will not translate directly — check the chart before you order.
3. Check the knuckle as well as the base. The band has to pass over the joint and still sit snugly at the base of the finger: snug enough to hold the sensor steady, loose enough to slide off without soap.
4. Choose by measurement, not by label. The range runs from size 7 to size 12, and we make this smart ring for women and men in the same sizes; the smaller end suits a slim ring finger, the larger end a broader index or middle finger.
5. Give it a full day before you settle. Wear it through a workday and a night. If it twists or leaves a mark, the next size up or the next finger along is usually the answer.

Use Scenarios

Training for an event. The weeks that decide a race are usually the ones where sleep slips first. Because the ring stays on through a heavy block, you can see whether the long Sunday session costs you the following two nights — a pattern that is invisible when you only look at one morning at a time. A sleep tracker ring makes the trade-off between volume and rest visible before it turns into an injury or a cold. Shift work and irregular hours. If your start time moves around, what matters is what a run of late finishes does to your sleep and how long it takes to come back afterwards. A fortnight of shifts shows up clearly in the weekly view, and so does the recovery when you return to normal hours. The same week, month after month. One cycle tells you very little. That comparison is what a smart ring for women is genuinely good at, and it is almost impossible to do by hand. Workplace wellness, done quietly. Teams that hand out wearables want something people will actually keep on. There is no screen and no notification, the ring records without interrupting a working day, and the weekly view is the part people bring to a conversation about workload. Gifting without guesswork. A ring is a personal purchase and the size is what decides whether it gets worn. If you are buying for someone else, the size chart and a ring borrowed from their jewellery box will get you further than a guess; silver is the safest choice of finish if you are unsure. Away from home. Travel is when routines break. A smart health ring keeps recording across time zones without you changing a thing, and the week after a flight shows how long your body took to settle back into its usual pattern.

Daily Health Signals

• Heart rate, day and night. Optical readings run continuously, so you can compare a tense meeting with a training session and see what actually moved your pulse.
• HRV as a recovery signal. Heart rate variability is tracked as a trend rather than a number to chase; it is the part of the picture that shows how well your body is absorbing the week.
• Blood oxygen. SpO2 is sampled through the night and the day, which helps when you want to know whether a dip lines up with a cold, a late night or a few days at altitude.
• Body temperature. Shown as a shift against your own normal rather than a single reading, so it can flag an oncoming illness before you feel it.
• Stress across the day. Stress appears as a curve rather than a verdict, so you can see whether yesterday's spike was the presentation or the third coffee.
• Steps, distance, calories and mapped sessions. Walking, running and cycling are recorded with the route drawn on the map in the app, so a session has a place attached to it as well as a duration.
• Cycles in the same timeline. This is where a smart ring for women does more than count steps: cycle length and the days around it sit beside your sleep, temperature and stress, so a fortnight of poor rest can be read against your cycle instead of blamed on willpower.
• One summary screen. Everything above lands in a single view built to be read in about thirty seconds. The point of a smart health ring is the summary, not the spreadsheet.

Getting Started

1. Charge it while you set up. Drop the ring into its case, install the companion app on your phone, and let both get ready at the same time.
2. Pair once. Enable Bluetooth, open the app and follow the pairing prompt. The ring appears as a device, and after that it reconnects on its own when it is in range.
3. Choose the finger. Most people settle on the index or middle finger of the non-dominant hand, with the sensor side against the underside of the finger where the signal is steadiest.
4. Give it a week. The first night is a baseline, not a verdict — the suggestions get more specific as a smart ring sleep tracker learns your pattern.
5. Leave it on. A wearable smart ring only pays off when it stays on through showers, workouts and weekends; the case makes topping up a habit rather than a chore.
6. Recheck the fit after a month. Hands change with weather and training load, and a ring that was snug in winter can feel loose in summer.

Purchase & Packaging
