10 Best Smart Rings 2026 in the United States

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 RingConn Gen 2 Air is a sleek, ultra-thin smart ring designed to track a variety of health metrics including sleep, heart rate, stress, blood oxygen, and even menstrual cycles through its AI-powered system. Its standout feature is the long battery life—up to 10 days on a single charge—making it convenient for continuous use without frequent recharging. The ring’s lightweight design (only 2.5 grams) and thin profile make it comfortable enough to wear all day and night without feeling bulky or distracting.

Compatibility with both iOS and Android devices is a plus, and you won’t have to pay a subscription fee for core tracking features, which adds to its appeal. It’s also water-resistant with an IP68 rating, meaning it can handle everyday water exposure as well as swimming and diving, making it durable for various lifestyles. The smart ring supports health savings accounts, which is great for those who want to use pre-tax funds for health-related purchases.

A unique sizing system requires purchasing a sizing kit to ensure a perfect fit, which might be a slight hassle compared to standard ring sizes but helps with comfort and accuracy. While the ring lacks GPS, it covers the essentials well and even includes a handy 'Find Your Ring' feature to locate it easily if lost. This makes the RingConn Gen 2 Air an excellent choice for users seeking a comfortable, stylish smart ring with strong health tracking and long battery life, especially those who are active and require water resistance. However, if GPS tracking or a broader app ecosystem is important to you, this might feel somewhat limited.

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.
