10 Best Smart Rings 2026 in the United States

The RingConn Gen 2 stands out as a smart ring designed primarily for health-conscious users, especially those interested in advanced sleep monitoring. One of its key strengths is the unique sleep apnea tracking feature, developed with input from universities and hospitals, which sets it apart from many other smart rings. It offers detailed real-time sleep data and personalized insights without requiring any subscription fees, which is a big plus for ongoing use. The battery life is impressive, lasting up to 10-12 days depending on ring size, and the included charging case can extend usage significantly, making it convenient for users with busy schedules.

In terms of compatibility, it works with both Android and iOS devices via the RingConn app, ensuring a broad user base can benefit from it. The ring is waterproof up to 100 meters, so it’s suitable for daily wear, workouts, and even swimming, while its ultra-thin and lightweight design enhances comfort, meaning you likely won’t notice it on your finger. The sizing kit offered before purchase is a thoughtful touch, helping you avoid sizing mistakes that could cause discomfort.

The device lacks GPS functionality, which some users might miss if they want location-based activity tracking. Its memory capacity is quite limited, so it relies heavily on syncing with the app. Also, while it offers many health metrics like heart rate, stress, and women's health tracking, the lack of a larger app ecosystem might feel restrictive for those looking for more third-party integrations. The RingConn Gen 2 is best suited for users seeking a discreet, comfortable smart ring focused on advanced health tracking, particularly sleep apnea, with solid battery life and no ongoing fees, but it may be less suitable if broader fitness features like GPS are important.

The Oura Ring 4 is a sleek and modern smart ring, designed primarily for health tracking, and offers several appealing features for users interested in monitoring their wellness. One of its standout strengths is its impressive battery life, lasting up to 8 days on a single charge. This means you won’t have to worry about recharging it frequently, making it convenient for daily wear.

In terms of health tracking capabilities, the Oura Ring 4 excels with features like heart rate monitoring and sleep tracking, which can be incredibly beneficial for those looking to improve their fitness and overall health. Its compatibility with Bluetooth allows it to connect easily to smartphones, enabling users to view their health data seamlessly through the associated app.

The design of the ring is another plus; it features a modern aesthetic that appeals to both men and women and is generally comfortable to wear throughout the day and night. Its water resistance adds to its durability, making it suitable for everyday activities. However, there are a few drawbacks to consider. Firstly, the lack of GPS means that it may not satisfy users who want to track outdoor activities more precisely. Also, while it has solid health tracking features, some users might find the data less detailed compared to larger fitness trackers or smartwatches. Additionally, the price point could be a concern for budget-conscious consumers, as it may not be the most affordable option in the market.

The Oura Ring 4 is a smart ring designed primarily for people who want detailed health tracking in a discreet and stylish form. It excels at monitoring over 50 health metrics such as sleep quality, activity levels, stress, heart health, and women’s health, using its advanced Smart Sensing technology that adapts to your body for accurate data. Battery life is strong, lasting up to 8 days with no screen or vibrations, which helps you stay focused without frequent recharging. The ring is crafted from durable titanium, making it lightweight, water resistant, and comfortable enough for all-day, 24/7 wear—even if you have sensitive skin.

Compatibility-wise, it works smoothly with both iOS and Android devices and integrates with many popular health apps, making it easy to sync your data. One downside to be aware of is the sizing: Oura rings use a unique sizing system that requires a special sizing kit before purchase, which might be inconvenient for some. Also, access to the Oura membership, which is necessary for full app functionality, involves a monthly or annual fee after the first free month. This subscription model might not suit everyone.

While the ring doesn’t have a display or GPS built-in, it uses your smartphone’s GPS for tracking workouts. This ring is ideal for those focused on improving their health and wellness through comprehensive, ongoing tracking without the bulk or visibility of a wrist device. If you want a minimal, fashionable device that tracks your body’s rhythms and provides insights, the Oura Ring 4 offers a well-balanced mix of comfort, durability, and detailed health data.
