Product Overview
Mayissi's gold smart ring keeps a continuous health record without asking for attention. The band is a closed, slim ring of metal with the sensor array built into the inner curve, so readings come from the base of the finger rather than from a wrist strap. Nothing lights up and nothing vibrates against your skin. There is no screen to check, which is exactly why it stays on through meetings, commutes and a full night's sleep. We built it as a smart ring for women who wanted their health data to sit beside the jewellery they already wear, and the warm gold finish lets it do that without looking like fitness hardware. The ring collects; the app explains. Open the app once a day or once a week, read how you have been sleeping, recovering and moving, then close it and get on with your day.
A health tracking ring you forget you are wearing There is no screen to tap and no strap to loosen before bed, so the record keeps running through meetings, commutes and sleep instead of pausing whenever the device becomes inconvenient. A finish that reads as jewellery rather than hardware The outside of the band is brushed gold and the inside is polished so it slides on smoothly. It sits comfortably next to a wedding band or a stack of thin rings, which is the reason many wearers keep it on instead of taking it off for dinner. One timeline instead of five apps Activity, sleep, stress, temperature and cycle share the same dates and the same view. If you have kept a separate cycle tracker ring or a standalone sleep app before, this is the difference you notice first. Measured from the finger, not the wrist The sensor array sits against the base of the finger, where a closed band cannot rotate or slide during the day, so your hands stay free while it works. It keeps improving after you buy it Feature updates arrive over the air through the app, so the ring is not frozen at the software it shipped with.
Key Features of the Smart Ring
- Daily activity — steps, distance and calories build up through the day, so an ordinary working day and a long walk are both recorded without you starting anything. - Sleep in stages — used as a sleep tracker ring it separates deep, light and REM sleep and logs naps separately, so an afternoon rest does not blur into the night's total. - Heart and recovery signals — this smart ring health tracker reads heart rate, heart rate variability, blood oxygen saturation and stress through the day and night. - Skin temperature — recorded automatically overnight and carried into the app's trends for you to compare across weeks. - Workout sessions — multi-sport modes capture a session with duration, distance, pace, cadence and calories, so a walk reads back as a proper record rather than a step count. - Small extras that earn their place — a remote shutter for your phone camera, a ring finder for the mornings it disappears, gesture control, and a couple of built-in games for the queue at the airport. - Morning check — the night's data has already synced by the time you pick up your phone; there is no button to press before bed and nothing to download in the morning. - Overnight — worn as a smart ring sleep tracker, it follows stages and wake-ups without a strap pressing into your arm, which is often the moment people who dislike watches at night change their mind. - Office days — nothing lights up in a meeting and nothing buzzes on your wrist; a ring that passes as ordinary jewellery does not interrupt anyone, including you. - Training — a run, a swim or a gym session is logged from the ring and lands in the same timeline as the night's sleep, so you can see how a hard session sits next to your recovery. - Cycle week — the cycle tracker ring sends the reminder, and you can look back over a month of sleep and stress to see whether what you feel matches what the ring recorded; that is what a women's health tracker is for in daily life. - Travel — one small ring and a charging case replace a watch and its charger, and time-zone shifts show up clearly in your sleep data for a few nights.
Precision Health Monitoring
Sleep is where most people start. As a smart ring sleep tracker it builds a picture across several nights rather than judging you on one bad Tuesday, marks where sleep breaks, works out whether you lean towards mornings or evenings, and suggests a bedtime window that fits that rhythm. It also shows how consistent your schedule has actually been, which is usually more revealing than the hours themselves. The analysis draws on more than sleep. Heart rate, heart rate variability, blood oxygen, skin temperature, activity and stress all feed the daily and weekly scores, which is why a hard training week and a stressful work week can look different even when your sleep hours are identical. The model behind those scores was developed with university and hospital research partners. Five guided meditation modes, covering stress relief, sleep and focus, run with live heart-rate feedback so you can watch your breathing settle. A smart ring health tracker is only as useful as the decisions it prompts, so the app keeps it plain: here is your week, here is what changed, here is the one thing worth adjusting. Read trends rather than single nights — a fortnight of data will tell you far more than one restless Thursday.
Women's Health & Cycle Reminders
- Reminders that assume you are busy — switch cycle reminders on once, choose the days you want to be warned about, and the ring keeps the count for you.
- A women's health tracker that shares one timeline — cycle phase sits beside sleep, stress and temperature, so you can see whether a poor night lands in the same week each month.
- Temperature across the month — nightly readings build a trend line you can read against how you actually felt, which is the column worth watching over weeks rather than days.
- Why a cycle tracker ring makes sense — you already wear it day and night, so there is nothing extra to remember, charge or sync.
- Built around women's health, not painted gold — this was designed as a smart ring for women from the start: the reminder, the temperature history and the cycle view are part of the product rather than an add-on.
Comfort, Design & Battery Life
At around 2.5 grams the ring is light enough that most wearers stop noticing it within a day. The band is thin, the profile is rounded and there is no clasp to sit on. A sleep tracker ring you keep on for seven or eight hours without moving has to disappear on the hand, and that was the design brief. Charging is magnetic: the ring drops onto the charging case and fills in about 1.5 hours. A full charge covers 5 to 7 days of typical use, with up to 15 days of standby while it sits off your finger. Used with the charging case, total runtime extends beyond 150 days, which makes it a sensible thing to pack for a two-week trip without a second charger. The routine stays simple — drop it on the case while you get ready and the battery never becomes something you think about. A rinse in fresh water after a swim and a wipe with a soft cloth are all the gold band needs to keep its finish looking new.

Sizing & Fit
- Measure the finger at the end of the day, when it is at its largest, and again in the morning if your measurement lands near a boundary.
- Compare that measurement with the Mayissi sizing chart. The ring follows its own size scale, so a size you know from another ring brand will not necessarily match.
- Measure the finger you will genuinely wear it on — many wearers pick the index or middle finger of the non-dominant hand — rather than a finger you think looks better.
- Aim for a band that slides over the knuckle without force but cannot spin on the finger; the sensors need steady contact to read consistently.
- If the fit feels borderline, send your measurement to our team before ordering instead of ordering two sizes and sending one back.
- Wear it for a full day when it arrives. A faint mark that fades within an hour is normal; a ring that leaves a deep groove or makes the fingertip feel cold is too tight.
Intended Use & Reading Accuracy
A wellness device, not a medical one
Mayissi is built to make everyday patterns visible, not to diagnose anything. There is no ECG channel here, no blood-pressure function and no sleep-apnea test, and no reading from this ring counts as a clinical result you should act on medically. If something in your history worries you — a resting heart rate that stays high for days, a cycle that stops following the pattern you know — the next step is a conversation with a clinician, and the app's history is there to make that conversation specific instead of vague.
Where the readings come from
Pulse and blood oxygen are read optically from the base of the finger, and skin temperature from contact with the inner band. That is a sound way to follow a trend, but it is sensitive to conditions: motion, cold hands, a band that can rotate, or a ring sitting on the wrong part of the finger will all move the numbers. Blood oxygen in particular is a comfort indicator rather than a clinical measurement, so read it across several nights instead of reacting to one figure.
Getting data worth relying on
Wear the ring on the index, middle or ring finger with the sensor side against the palm, snug enough that it cannot spin, and give it a minute of stillness for a clean resting reading. Compare like with like — the same time of day, the same finger. Treat the first week as a baseline while the app learns your normal range, because a health tracking ring that knows your ordinary week is far more useful than one judging a single night.
Trends beat single nights
One restless night is noise; two weeks is a pattern. The weekly and monthly views are where the ring earns its place on your hand: sleep shortening as a stressful stretch builds, resting heart rate drifting up through a heavy training block, temperature shifting in the days before your period. None of that needs a diagnosis to be worth acting on — it usually supports an earlier bedtime, a rest day or a lighter week.
What it does well, honestly
As a women's health tracker it is good at context, showing whether a poor-sleep week, a low-mood week and a particular phase of your cycle tend to arrive together. It is not a replacement for a test, a scan or a professional opinion. We would rather you trusted it for the questions it can answer than for the ones it cannot.
Purchase & Packaging
- In the box — the gold ring, the charging case with its USB cable, and a short user manual. Everything a smart ring health tracker needs to get started is included, with no separate charger to buy.
- One purchase, no subscription — a health monitoring ring that bills you every month is really a rental; this one is bought outright and the app's features come with it.
- Check the size first — sizes follow Mayissi's own scale and a health tracking ring lives or dies on fit, so compare your measurement with the chart before you choose.
- Packing — the ring travels in its retail box with the charger and manual, and the box is presentable enough to give as it arrives.
- If anything is unclear — ask our team about size, colour or current availability before you order; a quick question is easier than a return.

FAQ
What materials are used in the Mayissi Smart Ring?
The band is a closed piece of metal with a brushed gold exterior and a polished inner surface. Inside the curve sit the optical sensors — you can see the small green and red lights when the ring is working — and the electronics are sealed so the finished ring carries a 5ATM water-resistance rating. Because a health monitoring ring is worn against the skin all day, the inner surface is finished smooth rather than textured, which keeps it comfortable and easy to wipe clean.
Does the Mayissi Smart Ring work without a subscription?
Yes. You buy the ring once and the app's features come with it: sleep stages, activity, heart rate, blood oxygen, stress, skin temperature and cycle reminders are all available without a monthly or annual plan. We do not put core features behind a paywall, which for a smart ring for women you plan to wear for years is the difference between a tool and an ongoing bill.
How do I maintain the battery life of my sleep tracker ring?
Charge it fully — about 1.5 hours on the magnetic case — and top it up before it runs right down rather than letting it empty every cycle. A full charge gives 5 to 7 days of typical use, with up to 15 days of standby, and the charging case extends total runtime beyond 150 days. Keep it away from direct sun and hot surfaces such as a car dashboard, and store it on the case rather than loose in a bag when you are not wearing it.
Can I wear the Mayissi Smart Ring while swimming or exercising?
Yes. The 5ATM rating covers pool and open-water swimming, showering and workouts, so the ring stays on your finger rather than in a drawer. A smart ring sleep tracker is only useful if it survives the rest of your day, so the sealing was treated as part of the design rather than an afterthought. Rinse it in fresh water after a swim and dry it with a soft cloth.
How do I know which size to order?
Start with the sizing chart and measure the finger you will actually wear it on. A health tracking ring needs to sit snugly enough that the sensors stay in contact and the band cannot rotate, but loosely enough to slide over the knuckle without force. If your measurement falls between two sizes, send it to our team before ordering and we will help you choose.
Is the Mayissi Smart Ring a medical device?
No. It is a wellness device built for awareness and habit, not a diagnostic or medical device, and it is not intended to diagnose, treat or monitor a medical condition. If you have a health concern — including anything related to your cycle — speak to a clinician. What a women's health tracker like this does well is show you patterns across weeks so that conversation starts from something concrete.
