The Rise of Smart Rings: Beyond Oura in 2026

Smart rings are the fastest-growing category in wearable technology. What started with Oura as a niche health tracker has become a competitive market with Samsung, RingConn, and Ultrahuman all vying for your finger. The appeal is clear: discreet design, no screen fatigue, and a sleep-first approach to health tracking. Here is our analysis of where the smart ring market stands in 2026.

Why Smart Rings Are Growing

According to industry reports, the smart ring market is projected to grow at over 20% annually through 2028. Several factors are driving this acceleration:

• Screen fatigue. After years of notification-heavy smartwatches, many users want health tracking without the distraction of a screen on their wrist.
• Sleep-first design. Rings are significantly more comfortable to wear during sleep than watches. Based on published user surveys, sleep tracking is the number one reason people buy smart rings.
• Fashion compatibility. A titanium ring looks like jewellery, not technology. It does not clash with formal wear or draw attention in meetings.
• Samsung's entry. When Samsung launched the Galaxy Ring, it legitimised the category for mainstream consumers and brought smart rings to carrier stores and retail chains globally.
• Complementary use. Based on published user data, many smart ring owners also wear a smartwatch during the day and switch to the ring at night. The two form factors are complementary, not competing.

The Top Smart Rings in 2026

Oura pioneered the smart ring category and remains the benchmark. The Ring 4 introduces a slimmer profile and enhanced sensor array that, according to manufacturer specifications, provides more accurate readings by using the entire inner surface of the ring for sensing rather than concentrating sensors in one area. Continuous heart rate, heart rate variability, blood oxygen, skin temperature, and movement tracking feed into Oura's three signature scores: Sleep, Readiness, and Activity.

Based on published reviews, the Oura app remains the gold standard for ring-based health insights, with particularly strong sleep staging accuracy validated in published research studies. The main criticism is the mandatory subscription: after a free trial period, you must pay $5.99 per month to access your detailed health data. Without the subscription, the ring provides basic scores but locks away the insights that make it valuable. For a deeper look at Oura's capabilities, see our Oura Ring 4 detailed review.

Samsung's Galaxy Ring 2 is the most significant challenger to Oura's dominance. Based on manufacturer specifications, it tracks heart rate, HRV, skin temperature, and movement, feeding data into Samsung Health. The key advantage over Oura is that there is no subscription fee — all health data and insights are included in the purchase price.

According to reviewer consensus, the Galaxy Ring 2 excels in two areas: its integration with Samsung's broader ecosystem (Galaxy Watch data and Galaxy Ring data combine in Samsung Health for a more complete picture) and its gesture control features, which allow you to dismiss alarms, control the camera, and interact with your Samsung phone by pinching your fingers. The Energy Score — Samsung's equivalent of Oura's Readiness Score — uses Galaxy AI to provide personalised wellness recommendations.

The main limitation, according to published reviews, is that the Galaxy Ring 2 works best with Samsung phones. It is compatible with other Android devices, but some features are restricted. There is no iOS support at all, which immediately eliminates it for iPhone users.

RingConn offers an increasingly compelling alternative at a lower price point. The Gen 2 model, based on manufacturer specifications, includes the same core sensor suite as Oura — heart rate, HRV, SpO2, skin temperature, and movement — with no subscription required. Battery life is the longest in the category at up to 10 days.

According to published reviews, the RingConn app has improved significantly from the first generation, offering sleep staging, stress monitoring, and a wellness score. The hardware quality is solid, with a titanium construction and 100m water resistance. Where RingConn falls short compared to Oura, based on reviewer consensus, is in the depth and sophistication of its health insights. The data is all there, but the algorithms that interpret it are less mature. It works with both iOS and Android.

Ultrahuman has carved out a distinctive position in the smart ring market by focusing on metabolic health. The Ring Air 2 tracks the standard suite of biometrics, but the Ultrahuman app uniquely integrates with the company's continuous glucose monitor (the M1 Live) to provide a holistic view of how sleep, stress, activity, and nutrition affect metabolic health.

Based on published reviews, the Ultrahuman app provides a Movement Index that scores your daily activity across different categories (active calories, steps, workout intensity) and a Sleep Index with detailed staging. The PowerPlugs feature provides specific, actionable recommendations rather than just scores. According to reviewer consensus, Ultrahuman's approach appeals more to biohackers and fitness enthusiasts than to casual health trackers. The ring itself is one of the lightest in the category, and no subscription is required. It works with both iOS and Android.

The Ring vs Watch Debate

A question that comes up frequently in published discussions about smart rings: should you buy a ring or a watch? Based on our analysis of the category, here is how to think about it:

• Choose a ring if your primary interest is sleep tracking, passive health monitoring, and discreet wearability. Rings excel at 24/7 monitoring because you forget you are wearing one.
• Choose a watch if you want active workout tracking (GPS, pace, distance), smart features (notifications, apps, payments), and a display for real-time data during exercise.
• Choose both if you want the best of each: a watch for daytime workouts and smart features, a ring for comfortable overnight sleep tracking. Based on published user surveys, this combination is increasingly popular among health enthusiasts.

What to Consider Before Buying a Smart Ring

1. Sizing matters enormously. Unlike watches, a ring must fit precisely. Most manufacturers offer sizing kits (plastic or cardboard rings you wear for a day or two to find your size). Do not skip this step — an ill-fitting ring will give inaccurate readings and fall off.
2. Subscription costs. Oura requires a $5.99/month subscription for full data access. Samsung, RingConn, and Ultrahuman do not. Over two years, the Oura subscription adds approximately $144 to the total cost of ownership.
3. Phone compatibility. Samsung Galaxy Ring only works with Android (best with Samsung). Oura, RingConn, and Ultrahuman work with both iOS and Android.
4. What you cannot do. Smart rings cannot display notifications, play music, track GPS routes, make payments, or show you data in real time. If you need any of these features, you need a watch or tracker alongside the ring.
5. Battery life. All four rings last at least 7 days, which is significantly longer than any smartwatch. This means fewer disruptions to tracking and more consistent data.
