The best Smart ring slips easily onto your finger to track your activity, health, and sleep—forget smartwatches and fitness trackers. No distracting screens, no huge watch banging you on the face while you sleep, and considerably less charging time make smart rings a smoother, more elegant way to keep tabs on your body with data regularly offloaded to your smartphone.

Once the preserve of wealthy wellness fans, smart rings are becoming more affordable. Although our top pick is still the Finnish pioneer Oura with the Oura Ring 4 ($349), the company is now under pressure from upstarts like Ultrahuman and Ringconn, established fitness-tracking brands like Amazfit, and even tech giants like Samsung. We expect to see more entrants in the coming months, but for now, these are the best smart rings you can buy.

Updated February 2026: We added Oura’s ceramic ring, charging case, and blood labs, updates on the latest lawsuits and bans, a mention for Leep’s new smart ring, and updated prices.

Oura (Ceramic)

The original Oura Ring was a revelation that single-handedly created the smart ring category. This stylish, unobtrusive ring, popularized by biohacking billionaires, soon brought miniaturized fitness tracking to the masses. We were a little disappointed in the Oura Ring Gen 3 at launch because of delayed features and the switch to a monthly subscription, but we grew to love it. Now the Oura Ring 4 hits new heights. Making good use of its head start, the Oura is the best sleep tracker, one of the best fitness trackers, and the best smart ring for most folks.

Oura stands out for several reasons, but accuracy is paramount. Oura combines top-quality hardware capable of tracking your heart rate, body temperature, blood oxygen levels, and movement with smart algorithms that automatically recognize activities, break down each night’s slumber, and adjust goals based on your readiness. Over time (it takes a few weeks to detect trends), the Oura Ring chimed more closely with how I felt than any other tracker. It flagged changes in my temperature and heart rate when I was ill and prompted rest mode to help me recover. I love that it automatically picks up on hikes and core workouts, even tracking housework as a healthy activity. Oura is always adding new features like meal logging, enabling you to snap a photo of your plate and get an AI-powered breakdown of its nutrition and suitability.

With the release of the Ring 4, the Oura app was simplified to make it easier to digest your data (something that all models benefit from). Oura also participates in many groundbreaking women's health studies with a wide array of partners, including a new partnership with Quest Diagnostics that lets you get bloodwork as part of your subscription. The Ring 4 is also slimmer and lighter, and the improved sensors allow for a smooth inside (no more knobbly bits). We both tested the Brushed Silver model, which is simply the best-looking smart ring around, but there is now a ceramic version. I had issues with dwindling battery life and some scuffing with my silver Ring 4, problems I haven’t encountered with the ceramic version, but it is significantly pricier ($150 more than the standard Ring 4). The stylish portable charging case ($99) is great for travel and holds up to five full charges, but you must match the size to your ring. It would have been better if they had designed a charging case for any size of ring. There is also now multi-ring support in the app, so you can swap out rings with each outfit.

The downside is the $6 per month ($70/year) membership required to unlock personal insights, such as the temperature-trend tracking that caught my illness, in-depth sleep analysis, and restorative time to highlight relaxed states when stress levels are low. The subscription is worth it, but it does make this an expensive smart ring. You can save some money with the now-discounted third-gen Oura, which is still better than anything else on the market.

Samsung

Samsung

With the Samsung Galaxy Ring, exclusivity is a feature, not a bug. The Ring works seamlessly with the Galaxy Watch8 series and Galaxy Watch Ultra to extend each other's battery life by trading tasks and keeping tabs on your step count and activity while the other is charging. It comes in an attractive, clear charging case with an LED that shows you how much battery life you have left. It's a gram lighter than the Oura ring and noticeably lighter and slimmer. I found it mostly accurate compared to an Apple Watch Ultra, but it is a little generous with its sleep tracking because it doesn't have a gyroscope. It auto-detected workouts, even pool workouts (even if it did say I ran a half-mile farther than I did), and the heart rate tracking is very accurate. It also has a cycle-tracking feature powered by the fertility-tracking app Natural Cycles and uses skin temperature sensing to track when your period will come. It accurately predicted my period would be late, turning what would've been a stressful week much less so.

While you can use the Galaxy Ring with most Android phones, it's more expensive than the Oura (there's no subscription, though). The most useful features, like your daily Energy Score and wellness tips—what the company calls Booster Cards—also rely on Galaxy AI, which means you'll only be able to see them if you are using the Ring with a Samsung phone. But if you have a Samsung phone and Galaxy Watch, it has—dare I say—an almost Apple-like seamlessness and interoperability to it. You can even dismiss alarms with a Double Pinch gesture on your ring-wearing finger or remotely snap a picture (only available with Samsung phones).—Adrienne So

Ultrahuman

Ultrahuman

Note: Following a ruling by the US International Trade Commission (ITC), after a patent infringement lawsuit by Oura, Ultrahuman has not been allowed to import and sell its smart rings in the US since October 21, 2025. Ultrahuman’s statement says existing ring owners and anyone who purchases an Ultrahuman smart ring before the deadline will still get full subscription-free insights, feature updates, and warranty support. It's business as usual across the rest of the world. Some retailers are still selling existing stock (presumably imported before the ban).

Extremely slim, lightweight, and comfortable to wear, with a smooth finish inside and out, the Ultrahuman Ring Air is a serious contender that comes without the need for a subscription. This sensor-packed smart ring boasts an infrared photoplethysmography (PPG) sensor, a noncontact medical-grade skin temperature sensor, a six-axis motion sensor, and colored LEDs for heart rate monitoring and blood oxygen saturation. Like the Oura, it tracks your activity, spots trends in your heart rate variability and skin temperature, and offers sleep analysis.

While the sleep data is fairly accurate (a little generous), and Ultrahuman does a decent job of recording heart rate and basics, like steps, the workout tracking is its major weakness. I frequently found the heart rate tracking during exercise wildly inaccurate. However, Ultrahuman has now added automatic workout tracking, and it works well for basic activities like outdoor walks or runs. The company also now offers the Ultrahuman Home, a tracking device ($399) that monitors air quality, noise, and a few other things in your environment, and Blood Vision, a blood test service offering in-depth analysis of your blood.

The app offers some useful advice and notifications, such as delaying your morning coffee to allow adenosine to clear and taking in some morning sun. But it is not as accessible or elegant as the Oura app. The battery life also fails to match the Oura, and the Ultrahuman takes longer to charge. That said, you are looking at a one-off fee for the full-featured Ultrahuman Ring Air with no subscription, and the app has been steadily improving since its release. Ultrahuman has also added some nifty features, such as a smart alarm that wakes you when you are in a light sleep phase.

It's currently unavailable in the US due to a sales ban, so we'll have to see how things play out.

RingConn

Amazon

Note: Following Oura’s successful patent infringement lawsuit and the ITC ruling, Ringconn reached a licensing agreement with Oura, so its rings are still available in the US.

The latest smart ring from RingConn significantly undercuts its previous releases and almost everything else on the market. The RingConn Gen 2 Air is slimmer, lighter, and cheaper than the regular Gen 2 and offers subscription-free sleep and health tracking. There are PPG and temperature sensors inside, alongside a three-axis accelerometer. The Gen 2 Air tracks your steps, calories burned, heart rate, blood oxygen, and sleep. It can prompt you to get up when you’ve been sedentary for too long and warn you to take a deep breath if your stress levels spike. Compared to the Gen 2, it is made from cheaper steel, has a slightly shorter battery life (still up to 10 days), can’t detect sleep apnea, and comes with a basic charger instead of a nifty charging case. RingConn also added a tiny notch (like the Oura has) to help you align it correctly.

The RingConn Gen 2 Air is much more comfortable than previous models. (It is the most comfortable, light, and well-fitting ring that Adrienne has tried, bar the Oura.) It also has colored ring protectors to swap out with your outfits, if you're frustrated by having to wear the same jewelry every day. However, it has the same main problem: Workout tracking is limited and does not work well when your heart rate is elevated. It also consistently overestimated my sleep and slightly underestimated my steps and activity compared to my Oura and Apple Watch. RingConn added an AI assistant to the app that generates a plan for you, adjusting your targets weekly based on your activity and feedback. It’s fine. You can ask questions and get tips, but it didn’t add much for me. The Gen 2 Air struggles to compete with our recommendations above, but it is much cheaper, and the gap is closing. Ultimately, the RingConn Gen 2 Air is the cheapest subscription-free smart ring worth considering.

We have tested several other entrants in this category, some good, some bad, and some in between. Here is the lowdown on some of your smart ring alternatives.

Leep Ring 1 for $200: A new British smart ring that is affordable, subscription-free, and offers simplified, accessible stats on your activity, sleep, and stress? Sign me up. The Leep Ring 1 is slim and stylish, with a subtle diagonal indent to help you line up the knobbly internal sensors. It comes with a handy charging case that’s supposedly capable of providing an extra 60 days of charge. A fully charged ring is meant to last up to eight days. (I’ve been getting closer to five.) The app is straightforward (only available for iPhone right now, but there’s an Android app in the works) and gives you a big score out of 100 for sleep, balance (stress), and activity. Sadly, sleep is woefully inaccurate and tends to report that I’ve been asleep for my entire time in bed, even if I was watching TV or reading. Last night, it suggested I slept 8 hours 43 minutes (Oura says 6 hours 52 minutes). The activity and stress scores seem a bit more accurate, with step counts that were mostly within 100 or so of my Oura and Apple Watch (it was out by 1,000 one day). But the app could use some polish. For example, it doesn’t take into account that it’s only a couple of hours into the day before telling me my movement for today is “Bad.” I also lost data on the first night it ran out of battery, and there was no warning notification to tell me to recharge. It’s early days for Leep, and it’s priced very reasonably, but it needs to improve fast to compete.

Luna Ring 2.0 for $329: We had issues with charging and connectivity with the first-generation Luna Ring, but the Indian manufacturer seems to have made significant improvements in version 2.0. My Luna Ring 2.0 came with a jazzy wireless charging case (it is $29 cheaper with the regular charging dock) that promises up to 30 days of power. The ring is supposed to go five days between charges, but I found four was more realistic. I don't love the diagonal crease that marks the front of the ring, and it’s not as comfortable as my Oura. It boasts all the usual sensor suspects for tracking (optical heart rate, blood oxygen, PPG, skin temperature). Data is divided into sleep, readiness, and activity tabs in the busy app, with the obligatory AI option for advice and insights. There’s no subscription necessary, which is a big plus, and the data seemed reasonably accurate, but it’s definitely on the generous side. Comparing a full day to my Oura, the Luna thought I got an extra hour of sleep, burned 100 kcal more, and rated my readiness above 80 out of 100, while Oura scored much lower and picked up on something straining my body (I do have a cold right now). If you want a subscription-free ring, I prefer the Ultrahuman listed above.

Circular Ring 2 for $349: This ring is pretty, with rounded edges that make it slightly look more like jewelry than the Oura or Ultrahuman rings. I also like the closed charging case, which means you can bring it while traveling and recharge without a USB-C cable, and I also like that the ring pings me throughout the day when I'm in my best zone for productivity, working out, or caffeine. However, during my two-week testing period, I was plagued with persistent server issues and data processing delays that made it difficult to double-check any of my health metrics for accuracy, like heart rate, SpO2, or sleep data. It also makes it hard to recommend this ring right now. I will hold onto it for now and see if this improves.—Adrienne So

Movano Evie Ring for $269: When it first came out, the Movano Evie Ring was touted as the world's first fitness tracker designed specifically for women. I was very excited! It was recently updated to integrate with Apple Health (in the iOS version of the app), and you can now see your cycle day on your home page, manually log your basal body temperature, and manually add workouts. However, these new features are pretty underbaked compared to those offered by its competitors. Now that Oura and the Galaxy Ring can track periods so accurately, this ring's time may have passed. But it's relatively affordable, has no subscription fee, and has a blood oxygen sensor, so that's kind of nice. —Adrienne So

RingConn Gen 2 for $299: Despite a price increase over Gen 1 below, this is still a relatively affordable, subscription-free smart ring. RingConn retained the distinctive squared-off design, but this second-generation ring brought major improvements to sleep tracking (including sleep apnea detection), better battery life, and is very slightly slimmer and lighter. I found basic sleep and health monitoring solid (sleep is much more accurate than the first generation), but workout tracking is still a major weakness. Despite more available exercise types, you must manually trigger workout tracking, and it struggles with accuracy at higher heart rates.

RingConn Smart Ring for $99: Now heavily discounted, the original Ringconn is worth considering. A slightly squared-off design with beveled edges gives it a unique look, the health and sleep tracking work well, and it lasts four or five days between charges. It also comes with a handy battery case (enough for several charges on the go). However, I had trouble with data syncing, the app lacked proper workout tracking, and the data was sometimes inaccurate, though the app is steadily improving through updates.

Amazfit Helio Ring for $200: Purveyor of affordable fitness trackers like the Amazfit Active 2, I expected a competitive smart ring from Amazfit, but the Amazfit Helio is badly out of shape. I like the subtly textured bronze finish, but it is the only color you get. Sizes are also limited to 8, 10, or 12 for now (sizes 7 to 13 are coming). While it has similar capabilities to the smart rings above, the Helio was sometimes hopelessly inaccurate, with heart rate measurements wildly out of step with other trackers. It lacks automatic workout-tracking, battery life averaged three days for me, and the Helio frequently disconnected from the busy and confusing Zepp app. You don’t need a subscription, but there is Aura AI ($70/year) for sleep insights and content or Fitness ($30/year), which includes an AI coach. They are expensive and confusing. (Why have two separate subscriptions?) The Helio works much better in conjunction with a smartwatch (I tried it with the Amazfit Cheetah Pro), as it can merge the data, but as a standalone device, it is impossible to recommend.

How Do I Choose the Right Smart Ring Size?

Some smart rings come in standard sizes, but there is variation, and half sizes are rare, so it's worth taking some time to ensure you get the correct ring size. Most manufacturers will send you a free sizing kit, enabling you to wear a dummy ring for 24 hours. (You may have to buy the ring directly from the manufacturer to get this kit for free.) You should absolutely do this. Bear in mind that your fingers swell and shrink throughout the day. Your smart ring should be snug to enable the sensors to measure accurately, but you will have to remove it regularly to charge, so you don’t want too tight a fit.

Which Finger Should I Wear My Smart Ring On?

You can wear your smart ring on any finger, but most manufacturers recommend wearing these gadgets on your index finger, though the middle or ring finger can also work. These three fingers all have large blood vessels for more accurate pulse monitoring. What’s really important is that the ring fits tightly and securely around the base of your chosen finger, so if you have a big knuckle and a narrower finger base (more common with the middle or ring finger), this can be tricky. I recommend wearing it on the index finger of your less dominant hand because I found wearing it on my right index finger, as a right-handed person, led to more damage on the ring and scrapes on some things I touched.

Which Smart Ring Finish or Color Is Best?

All the smart rings we tested combined tough titanium with a sensor array on the inside, but the coatings and colors vary. If you are hard on rings, a silver or gold finish will likely suit you best, as there is less risk of damage. My Oura and Ultrahuman rings with black finishes have visible scratches and chips after a few months. Our Galaxy Ring test unit has been on a tester's finger for more than a year, and the edges of the titanium black ring now look silver.

The Oura, Samsung, and Amazfit rings have tiny dimples to help you align the sensors. While I prefer the smooth finish of the Ultrahuman, I suspect correct placement aids accuracy enormously.

How Do I Care for My Smart Ring?

Most smart rings are durable, but if you want to avoid damage, you should remove your ring when working with tools, weight lifting, washing pots and pans, or even cleaning the sink. If your ring is likely to rub against a surface, take it off. I found this was a bigger problem wearing a ring on my index finger than with the middle or ring finger. I scratched the Oura and Ultrahuman rings when gardening, moving boxes, and using a dumbbell. Titanium is also tough enough to damage surfaces in your home. I gouged the porcelain of my sink and marked the inside of a mug with the angular Ringconn. All the smart rings we tested are water resistant, so you can swim or shower without taking them off.

How Often Do I Need to Charge My Smart Ring?

Smart rings come with a charger and cable, but you will generally have to provide your own wall adapter. From dead, they take anywhere from an hour and a half to three hours to fully charge, but you should avoid letting the battery run down completely, or you run the risk of losing health data. We tested the smart rings above with all the bells and whistles turned on, so our battery life estimates are lower than the manufacturer's claims.

What Smart Ring Features Should I Look For?

Most smart rings will track your sleep, heart rate, and temperature. If you want to keep an eye on your sleep and get health insights unobtrusively and comfortably, smart rings are ideal. Fitness tracking varies, with most smart rings offering basic step counts and movement, some offering manual workout tracking, and others offering automatic workout recognition. But you can expect more depth and accuracy from a traditional fitness tracker or smartwatch. Combining a smart ring with an Apple Watch or Fitbit makes for a seamless experience, allowing you to take off the watch and let it charge at night without gaps in your tracking.

Smart Rings or Smartwatches?

In the past few years, we've fielded many questions about why someone would get a smart ring instead of, or in addition to, a regular fitness tracker or smartwatch. Here are a few reasons why you might consider it:

Better battery life. A smart ring is smaller and usually (if not always) has better battery life. It's a helpful addition to your repertoire if you hate missing a couple hundred, or a thousand, steps while you're charging your smartwatch every day.

Sleep tracking. It's no coincidence that our favorite sleep tracker is a small, unobtrusive ring. Maybe you're tired of having your enormous Apple Watch Ultra smack you in the face every time you turn over. (Or maybe you're charging it instead!)

Cycle tracking. Many watches and fitness trackers now feature a skin temperature sensor that's sensitive enough to detect when you're sick or drinking alcohol. However, in Adrienne's testing so far, only the Samsung Galaxy Ring and the Oura have been accurate enough to track her menstrual cycle.

Finally, fashion. Watches are a statement and a status symbol; a smartwatch often says nothing more about your preferences and choices besides “I don't like missing meetings.” Almost everyone we know who has bought a smart ring has done so because they have a hand-me-down Cartier Tank, or a fun Casio or Swatch, that they don't want to give up. If this is you, good for you! And get a ring!

How We Test

We have been wearing smart rings continuously for several years (sometimes two or three at a time), so we have a good handle on what makes a smart ring worth buying. Every smart ring we test has been worn for at least a month, usually longer, and we always compare its tracking data against our top pick (Oura) and with other smartwatches and fitness trackers (Apple Watch).

What We're Testing Next

We are re-testing the Circular Ring 2 and the upcoming RingConn Gen 3.
