10 Best Smart Rings 2025 in the United States

The RingConn Gen 2 is a smart ring designed especially for people who want reliable health tracking without the hassle of subscriptions. A major highlight is its unique sleep apnea monitoring feature, which uses advanced technology developed with expert institutions to provide real-time data and personalized sleep insights. This makes it stand out among smart rings for those concerned about sleep quality and breathing issues. It also tracks stress, heart rate, women’s health, activity, and blood oxygen levels, giving a well-rounded picture of your health.

The ring’s battery life is impressive, lasting 10 to 12 days depending on size, and the smart charging case extends this to over 150 days, so you don’t have to charge often. Comfort and design have been carefully considered too—the ring is ultra-thin, light, and comes with a sizing kit to ensure a perfect fit, which is important since smart rings need to be worn all day and night. Durability is solid with water resistance up to 100 meters, meaning you can wear it during swimming or workouts without worry.

It is compatible with both Android and iOS devices and doesn’t require ongoing fees, which simplifies use. The ring does not include GPS, so location-based tracking isn’t available, and it requires Bluetooth connection to sync data. Additionally, the unique sizing system requires using their sizing kit to avoid purchasing the wrong size. This smart ring is a great option for anyone looking for health-focused monitoring, particularly for sleep apnea, who values long battery life and comfort without subscription costs.

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.

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.
