If you've been comparing smart rings, you've probably noticed something odd: the price on the product page isn't the price you'll actually pay. The   Oura Ring 4   starts at $349. Then it asks for $5.99 every month — not for new features, but to keep using the ones the ring already collects. Stop paying and your sleep stages, readiness score, HRV trends and cycle insights quietly disappear, leaving you with an expensive step counter. That's why "smart ring without a subscription" has become one of the most searched questions in the category. This guide breaks down what a smart ring really costs over three years, what you lose when the payments stop, and how Mountova approaches it differently. The math nobody puts on the product page Here's the same comparison over five years, using published US pricing as of October 2026. Oura includes 12 months of membership free with a new ring, which we've factored in — this is the honest, best-case version for Oura.   Oura Ring 4 Mountova Ring Hardware, one time $349 $99.80 Monthly fee $5.99 $0 Annual fee $69.99 — Total after year 1 $349 $99.80 Total after year 3 $493 $99.80 Total after year 5 $637 $99.80 Feature access Full insights require an active membership Every metric included, no paywall Over three years, the difference is   $393.20   — nearly four times the cost of the Mountova ring itself. Over five years it's $537.20. And that gap only grows: Oura's membership renews automatically, while a one-time purchase is permanently done. To be fair to Oura, the ring is a genuinely good product and the subscription is the cheapest in premium wearables (WHOOP runs $20–30/month). The question isn't whether Oura is worth it. It's whether   you   want a device that stops being useful the month you stop paying. What actually happens when you stop paying Oura This is the part most reviews skip. Cancel the membership and you keep: Step count and calorie estimates Basic sleep duration Basic heart rate and blood oxygen Body temperature readings What you lose: sleep stage breakdown, readiness score, HRV trends, stress resilience, cycle insights, illness detection, activity goals, and your full data history and export. In other words, the insights that make a smart ring worth wearing — the ones you actually bought it for — are the exact ones behind the paywall. A ring without them is a step counter on your finger. What Mountova tracks, with no subscription attached Mountova was built on a simple premise: you buy the ring, you own the data. Everything below is included in the purchase price, with no membership, no premium tier, and no unlock fee — now or later. Sleep stages   (light, deep, REM) with an overall sleep score Heart rate   and resting heart rate trends HRV   (heart rate variability) for recovery insight Stress level tracking   through the day Skin temperature trends Menstrual cycle insights , based on your skin temperature trends 100+ sport modes   for workouts and daily activity It connects to both iPhone and Android over Bluetooth — no ecosystem lock-in — and runs   5–7 days   on a charge, refilling in about 80 minutes on its magnetic dock.   Where Oura still wins — and when you should pay for it An honest comparison has to say this out loud. Oura Ring 4 does things Mountova doesn't: Respiration rate tracking   during sleep Water resistance to 100 m   versus 5ATM on Mountova 40+ third-party integrations , including fertility and health apps A larger data set   for its scoring models, built on years of users If respiration tracking or deep app integrations are non-negotiable for you, Oura is the right call — and the monthly fee is the price of admission. If what you actually want is sleep, recovery, stress and cycle insight you can check every morning without another bill, that's exactly the gap Mountova fills. How the no-subscription options compare in 2026 Oura isn't the only ring on the market anymore, and the fee-free field has grown.

Two things make it easy to get right: Use the size measurement guide on the product page.   It walks you through measuring your finger at home. Measure   3 times   and use the   average of the three   as your size — a single measurement is unreliable because finger size shifts with temperature and time of day. Still unsure? Order a Mountova Sizing Kit first.   It's $9.98, and the full amount is   credited toward your ring purchase   — so it effectively costs you nothing to try before you buy. Mountova comes in sizes 6–11 and five finishes:   Ceramic Pink, Silver, Gold, Black and White .   Charging: 80 minutes, once a week A 5–7 day battery means charging is a weekly habit, not a nightly one. Set the ring on its magnetic dock while you shower and it's back to full in about 80 minutes. No subscription, no proprietary cable to replace, no battery service plan. Who Mountova is for — and who it isn't A good fit if you… Consider something else if you… Want sleep, recovery and cycle insight without a recurring bill Have been put off Oura by the $5.99/month Switch between iPhone and Android, or dislike ecosystem lock-in Want to wear it overnight and forget about charging Need respiration rate tracking Want to swim to depth or dive with the ring on Depend on a large third-party app integration ecosystem Want the most mature scoring algorithm on the market Frequently asked questions Does Mountova require a subscription? No. There is no subscription, and there never will be. Every metric Mountova collects is included in the purchase price — no monthly fee, no premium unlock, no charge to access your own data. Does the Oura Ring require a subscription? Yes. Oura charges $5.99/month or $69.99/year after the first 12 months included with a new ring. Without an active membership, sleep stage analysis, readiness scores, HRV trends and cycle insights are unavailable. How much does a smart ring cost over three years? An Oura Ring 4 costs about   $493   over three years ($349 hardware plus $144 in membership). A Mountova Ring costs   $99.80   once. The gap widens every year the subscription renews. Can I track my cycle without a subscription? Yes. Mountova provides menstrual cycle insights based on your skin temperature trends, included with the ring. Note that Mountova is a general wellness device, not a medical or contraceptive device. How do I know which size to order? Follow the size measurement guide on the product page, measuring your finger three times and averaging the results. If you're between sizes or want certainty, order the $9.98 Sizing Kit first — the full amount is credited toward your ring purchase. Does Mountova work with iPhone and Android? Yes. Mountova pairs with iPhone 8 or newer running iOS 14+, and with Android 8.0+ devices with Bluetooth 5.0. Both platforms get the same app and the same features. The short version:   Oura is a great ring with an ongoing bill. Mountova is   $99.80, once   — sleep stages, HRV, resting heart rate, stress, skin temperature and cycle insights included, with nothing to cancel. Mountova is a wellness device and is not intended to diagnose, treat, cure, or prevent any disease.
