Oura Ring is the category originator, and the company remains the leader with its new Oura Ring 4, which replaces the Oura Ring 3. It improves over the previous-gen model with all-around 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 you can enjoy the automatic workout tracking, which we liked very much.

The Oura Ring 4’s battery life is downright phenomenal, though we wish this model came with a charging case for on-the-go charging. That said, considering it lasts up to a week, you could go on vacation and not even need the charger.

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 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 based on your personal 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.

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 organized better, but I love the breadth of information it provides, as well as smartphone notifications that advise 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 I’d confidently rely on for everything my 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.

Though it’s a value option, the Circular Ring 2 is solid. Although I have not yet reviewed this model as indepthly as the others on this list, I did review the previous-generation Circular Ring Slim, which provided an introduction to brand as well as the app experience. I was also able to see an early version of the Circular Ring 2 at CES 2025 in Las Vegas earlier this year.

It packs in unique and useful features, including FDA-cleared Afib detection, enhanced ECG, and blood pressure and glucose monitoring coming soon. The Slim ring version didn’t look as elegant as its competition, but there is an improvement with version two, which boasts a glossier look and is made with the more durable titanium. But honestly, we didn’t have any complaints about the Slim’s durability, even after running it through several cycles in the washing machine, and it came out a little scratched but fully functioning.

The Circular Ring 2 doesn’t incorporate haptic vibrations like the Slim (alerting you of an alarm or when to take medication, for example).

The app is powered by a helpful AI wellness assistant called Kira+ that asks questions about you, assesses your behavior, and, over time, makes recommendations to improve your health and wellness or help you adopt better habits. She’s like a personal virtual wellness coach. When we used the app with the Slim version, it was buggy, sometimes failing to sync or constantly crashing. With the Circular 2, the app has been completely redesigned to more resemble both the Oura and Ultrahuman apps, but based on recent app ratings, there are still some bugs. However, with firmware updates and continuous improvements, the experience will hopefully get better. When it works, it works well, providing tons of useful stats organized logically so it’s easy to read and interpret..

Get up to eight days of battery life per charge, seven with Performance Mode, down to about two days with Performance Mode, which is a drastic improvement from the Circular Ring Slim. I’ll have to wait to test it to confirm real-world usage, however. Another big improvement is that unlike the tiny USB-C charger that came with the Circular Ring Slim, this one comes with a wireless charging case.

We’ll provide more concrete details on the Circular Ring 2 once we get our hands on it. Stay tuned.

• Colors: Black, Silver, Gold
• Dimensions: 7mm wide, 2.6mm thin

We don’t recommend the Samsung Galaxy Ring for owners of any smartphone brand other than Galaxy devices. While it technically can connect, 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.

I don’t see tremendous 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 8 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 Galaxy phone companion.

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.)

• Colors: Sunlit Gold, Rose Gold, Stardust Silver, Lunar Black, Midnight Black
• Dimensions: 8mm wide, 2.9mm thin

• 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 I appreciated in the original Luna Ring, while introducing a slightly slimmer design and faster processing. The app can be slightly overwhelming with all the data that’s collected, but you also get a daily health digest as a glanceable summary.

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 and even help you find a suitable pre-workout drink or healthy snack. The Luna Ring 2’s new Life OS ecosystem is said to offer enhanced performance and more personalized insights, although we haven’t had the opportunity to try it yet.

There are only 10 workouts to choose from, but the “freestyle workout” option serves as a catch-all in place of workouts that are missing, such as indoor cardio or strength training. If you manually add a workout after the fact, more options appear, offering a basic calorie-burn calculation based on your effort during that time and activity.

Battery life is decent: We got 4 to 5 days per charge with the original ring, and it’s expected to be the same with the new one. 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, which helps you understand sleep patterns and your body’s internal clock, and how to adjust sleep schedules to align with your natural rhythm. The Luna Ring 2 also offers on-demand biomarker measurement, allowing users to measure parameters such as SpO₂, skin temperature, heart rate, and stress instantly, rather than passively.

Stay tuned for our more detailed insights on the brand new Luna Ring 2, once we’ve gotten our hands on that model.

• 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
• Rated battery life: Up to 4 days
• Compatibility: Android, iOS

The Amazfit Helio is tailor-made for runners, so if you don’t partake in that activity, 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 rings 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 decent smart ring for runners, but it isn’t really the best option for anyone else.
