Oura Ring is the category originator, and the company remains the leader with its Oura Ring 4, which replaces the Oura Ring 3. It improves on the previous-gen model with an all-titanium construction and recessed sensors for a thinner, sleeker look.

Smart Sensing ensures continuous, accurate data capture, even if the ring shifts around on your finger while you fidget or sleep. Speaking of sleep, Oura remains one of the best for tracking sleep with detailed, accurate reports. We named its predecessor, the Oura Ring 3, among the best sleep trackers, and the Oura Ring 4 earns that title, too, especially with the addition of Smart Sensing.

All the data collected by this comfortable, ultra-durable ring is accessible in the intuitive, well-organized Oura app. We love the additional features like menopause and perimenopause tracking, meal logging, and even Symptom Radar, which can measure and warn you about a potential cold. You can manually track workouts or enjoy automatic workout tracking, which we liked and works well.

The Oura Ring 4's battery life is phenomenal, though we wish this model came with a charging case for on-the-go charging. That said, given that it lasts up to a week, you could go on vacation without even needing the charger. Plus, Oura launched an optional charging case that works with the Oura Ring 4, but it's sold separately. We'd recommend it for neater storage and on-the-go charging.

The elephant in the room is its subscription, which costs $5.99 per month or $69.99 per year. Let's be clear: the smart ring isn't worth it if you're not going to use the subscription, so factor the subscription into the up-front cost. The fee is less than the cost of a coffee and a muffin in the morning once a month, and we think it's worth it to keep your health on track.

The Ultrahuman Ring Air is one of the more elegant-looking smart rings. Available in a wide range of sizes and in stylish colors, it's comfortable to wear all day and night. It's water-resistant, too.

What sets it apart is the PowerPlugs add-ons in the app, which you can select to suit your needs. Love to drink coffee? Use Caffeine Window to find out when it's the best time to indulge (or refrain) from a cup of java. Do you work an odd shift? There's a mode that adjusts tracking based on your unique schedule. Choose from so many free ones, like vitamin D and circadian rhythm, or more advanced PowerPlugs like AFib detection, available for a nominal monthly fee. Ultrahuman partnered with four-time Olympian Les Mills for a PowerPlug that provides workouts, with a monthly or annual add-on fee as well.

In real-world tests, the battery lasts about three days when using Turbo Mode, which activates all features, though you can use Chill and Critical Battery Mode in a pinch to limit functions and extend battery life.

The app could be better organized, but we love the breadth of information it provides, as well as smartphone notifications that advise you when it's time to get some sun or praise you for getting better-quality sleep last night. You also get weekly reports. Use it to track all types of workouts, activities, and sports.

It's one of the few smart rings we'd confidently rely on for everything our smartwatch typically tracks. The fantastic all-around smart ring will suit just about anyone, whether your priority is fitness, health and wellness, or passive vitals tracking.

Ultrahuman launched the Ring Pro in early 2026, which boasts an impressive up to 15-day battery life and comes with a charging case. The company also added the new Jade AI assistant to the app, which can provide real-time guidance. We haven't had the chance to test that unit yet.

• Size range: 5 to 15
• Material: Titanium, epoxy inner ring
• Colors: Black, Silver, Gold
• Dimensions: 7mm wide, 2.6mm thin
• Weight: 2.3 grams to 3.2 grams (depending on ring size)
• Water and dust resistance: 10ATM, IP68
• Rated battery life: Up to 7 days
• Compatibility: Android (Galaxy phone to unlock all features)

We don't recommend the Samsung Galaxy Ring for owners of any smartphone brand other than Galaxy. While it can technically connect to other Android phones, you'll lose out on Samsung-specific features like Energy Score and AI-powered tips. For Samsung Galaxy phone owners, however, it's worth considering.

The design is basic, but it's comfortable to wear. It excels in battery life, especially with the charging case that lets you pop it into a purse or pocket for on-the-go charging. It's ultra-durable with a 10ATM rating, which means you can wear it virtually anywhere, even during water sports.

We don't see much value in wearing it alongside a Galaxy Watch, one of our best smartwatches, unless you want to use it for passive secondary tracking. Use a watch like the Samsung Galaxy Watch 9 to track workouts, walks, and other activities, and the ring to track 24/7 heart rate, sleep data, and vitals.

All the data is presented in the Samsung Health app, which is basic but easy to navigate. If you want to limit distractions, however, the Galaxy Ring is a solid companion for Galaxy phones.

There are some cool additional things you can do with the ring, too, like use gestures to control your phone. You can double-pinch your finger to silence an alarm or take a photo, for example. (Note that you can use gestures with the latest Galaxy Watches, too.)

• Size range: 6 to 14
• Material: Titanium with PVD coating, hypoallergenic plastic inner ring
• Colors: Sunlit Gold, Rose Gold, Stardust Silver, Lunar Black, Midnight Black
• Dimensions: 8mm wide, 2.9mm thin
• Weight: 3 grams to 4 grams (depending on ring size)
• Water and dust resistance: 5ATM
• Rated battery life: Up to 7 days
• Compatibility: iOS, Android

The Luna Ring 2 retains the simple design, comfortable fit, and AI-driven insights that we appreciated in the original Luna Ring, while introducing a slightly slimmer design and faster processing. It also ups the ante with the LifeOS system and voice logging feature. The amount of information in the app can be overwhelming, but it's organized nicely. You get a daily health digest as a glanceable summary. The app is slow to load and sync, though, so you'll need to exercise some patience.

Summon Luna AI to inquire about stats and get tips and suggestions on how to improve. The virtual assistant can guide you through interpreting data, even help you find a suitable pre-workout drink or healthy snack. The LifeOS ecosystem is where this smart ring experience really shines. We love that you can simply say "Hey Siri, Track With Luna" from an iPhone, then log things like your meals, mood, supplements, and more (as of now, you can't log medications). It intelligently captures the information and provides analysis, like the breakdown of protein, carbs, and fat in your meal and advice on what to eat for dinner to ensure a balanced diet and maintain your energy. It's one of the most advanced AI systems we've seen for a smart ring to date.

There are only a handful of workouts to choose from, but the freestyle option serves as a catch-all for missing workouts, such as indoor cardio or strength training. If you manually add a workout after the fact, more options appear. We'd recommend manually starting and stopping workouts as the automatic detection didn't work well for all workout types. The data captured is accurate compared to other trusted smartwatches and trackers worn to compare, though.

Battery life is respectable: We got about a week per charge, a notable increase from just four to five days with the original ring. The big difference is that the Luna Ring 2 comes with a charging case that stores up to six additional battery cycles.

Sleep tracking is detailed, offering insights into the circadian midpoint, sleep patterns, and your body's internal clock, helping you adjust sleep schedules to align with your natural rhythm. The Luna Ring 2 also offers on-demand biomarker measurements for SpO₂, skin temperature, heart rate, and stress. Overall, this is a great smart ring if you want a fully holistic picture of your health and wellness.

• Size range: 8, 10, 12
• Material: Titanium alloy, resin inner ring
• Colors: Gold-ish
• Dimensions: 8mm wide, 2.6mm thin
• Weight: 3.8 grams
• Water and dust resistance: 10ATM

• Compatibility: Android, iOS

The Amazfit Helio is tailor-made for runners, so if you don't run, this isn't the right smart ring for you. But if you are a runner, the Amazfit Helio is a solid option that isn't too expensive and provides useful guidance and tracking.

Stylish with a lovely dotted pattern, the comfortable ring offers an impressive 10ATM water-resistance rating and lasts up to three days per charge. It only tracks four workout types—running, walking, cycling, and treadmill—so if you don't predominantly do any of these, it's best for secondary tracking alongside a smartwatch.

Runners will especially love the advanced metrics it captures, including training load, exertion load, and recovery. It can even analyze your runs and generate race predictions, which is perfect if you're training for a 5K.

The app, while buggy, provides useful information. But it's not as enticing to revisit as other smart ring apps are. This is largely because there are no notifications or additional insights that entice you to visit more often.

One feature that stands out is Zepp Aura, which includes customized sleep and relaxation sounds and a chatbot that can answer wellness-related questions. That might include information about how your diet affects sleep or what caused your poor sleep quality the night before. It's a solid smart ring for runners, but it's not the best option for anyone else.

• Sizes: 6 to 13
• Material: Titanium outer and inner ring
• Colors: Silver, Black, Stealth, Brushed Silver, Gold, Deep Rose
• Size: 6.09mm wide, 2.28mm thin
• Weight: From 2 grams (depending on size)
• Water and dust resistance: IP68
• Rated battery life: Up to 6–9 days
• Compatibility: Android, iOS

Oura launched the Oura Ring 5 in early 2026, which is the brand's slimmest smart ring to date. If you want a smart ring that truly looks like a piece of jewelry, this is it. It's incredibly slim and lightweight, 40% smaller than the Oura Ring 4. This design not only looks elegant, but it also allows for better skin contact and thus presumably more accurate tracking. So, there are practical benefits, too.

The LEDs are purportedly more powerful and offer more consistent readings. The 12 stronger signal pathways are said to offer better accuracy across more finger types and skin tones. We wore the Oura Ring 5 for a week, and it's just as accurate as the Oura Ring 4; the fit is wonderfully comfortable for slender fingers.

You get the identical app experience as you would with the Oura Ring 4 and other Oura Ring models, with all the latest upgraded features. Naturally, this means you also need the membership to get the most out of it. But what we love about Oura is that the company is continuously adding new features to the app to add value. Some of the latest include live activity tracking for following metrics from a workout on your phone and Health Radar to continuously measure key biometric signals and pick up on noteworthy patterns.

It's incredible that despite the much thinner size, Oura has rebuilt the battery and firmware to be more efficient so you get up to nine days per charge, closer to six with real-world usage, which is still longer than the Oura Ring 4. After three days of 24/7 wear, the battery was still at 66%.

We wish this model came with a charging case, but alas, it still ships with the same standard charging dock you can't take with you. There is a $99 charging case you can purchase separately to keep the ring powered up on the go for up to one month, if you so desire.

It's recommended to get the sizing kit even if you are upgrading from the Oura Ring 4. That said, after our 24-hour try-on period, we ended up with the same size as our Oura Ring 4. But you may not have the same experience. For someone with slimmer, daintier fingers, the Oura Ring 5 is a solid choice that looks markedly different from the Oura Ring 4.

• Sizes: 6 to 13
• Material: Titanium
• Colors: Matte Black
• Size: 8mm wide, 2.7mm thin
• Weight: 3–4 grams (depending on size)
• Water and dust resistance: 5ATM
• Rated battery life: 7+ days
• Compatibility: Android, iOS

You probably haven't heard of this smart ring, as it started as a Kickstarter campaign. Backers should start receiving the product in August 2026, with general availability scheduled for mid-September 2026. But we were one of the first to get our hands on a sample for testing. It stands out because you can take on-demand blood glucose assessments and blood pressure checks.

The ring is basic-looking; we might even call it boring. But if you want a simple ring to track stats in the background versus a fashion accessory, it fits the bill. Sizing seems slightly smaller than most others, so keep this in mind as well.

The blood glucose risk assessment testing is useful, though it's impractical since you need to fast for eight hours (or do a two-hour non-fasting test) then sit still as it runs for five minutes. Do this at least three times in a seven-day period to determine a baseline and get the most accurate results. It's not meant for those who have diabetes, but it's a useful way to keep on top of blood sugar if you have concerns. Once the blood pressure feature is ready, you would have to take an initial baseline measurement using a cuff, then use the ring exclusively from there. Keep in mind it isn't a medical device and should not be relied on for diagnosis.

Beyond those unique measurements, when it comes to general activity and vitals tracking, we were surprised at how accurate this ring is. When comparing data collected from the Pin Pulse to other smart rings and smartwatches worn at the same time, there was little variance. One thing we will note, however, is that the sensors on the underside illuminate bright green when they're measuring something, which can be distracting.

The app is nicely organized and easy to navigate. VitalPlugs are essentially the Pin Pulse version of Ultrahuman's PowerPlugs. Only Mood Track was available at the time of our review, but we suspect more will be added in the future. We love that the list of workouts you can choose from is among the most exhaustive we've seen. Battery life is not as generous as expected, at closer to four or five days per charge, but that's still solid.

The Pin Pulse smart ring keeps up with the bigger brands, offering reliable tracking and unique data capture that you don't find in other options. We can't definitively say that the blood glucose and blood pressure measurements are accurate. But as a basic smart ring to track it all, the Pin Pulse provides accurate reporting, unique add-ons, and doesn't require a subscription.
