10 Best Smart Ring 2025 in the United States

The RingConn Gen 2 is a smart ring designed for users interested in comprehensive health tracking with a special focus on sleep apnea monitoring—a feature not commonly found in similar rings. It's lightweight and comfortable to wear daily, thanks to its thin design and careful sizing kit that ensures a good fit. This ring tracks a range of health metrics including activity, sleep quality, heart rate, stress levels, and women’s health, giving a well-rounded view of your wellbeing. Battery life is impressive, lasting 10 to 12 days on a single charge, which is convenient for those who don't want to charge their device frequently. The included charging case extends usability, with a total battery life exceeding 150 days when combined with charging cycles. It also boasts strong water resistance, rated for up to 100 meters, making it suitable for swimming and other water activities without worry.

Another plus is that it works with both Android and iOS devices and does not require any subscription fees to access its app and features, which makes it cost-effective over time. The ring supports over-the-air software updates, so it can improve and add features as new technology becomes available. On the downside, it doesn’t have GPS, which some users might miss for outdoor activity tracking, and its memory capacity is quite limited compared to some other fitness devices. Additionally, while it tracks many health metrics, the ring’s size and fit might require some careful measuring to avoid discomfort or inaccurate readings.

The RingConn Gen 2 is well suited for those seeking an advanced, hassle-free health tracker in a subtle form, especially if sleep apnea monitoring is important to them, but it may be less suitable if detailed GPS-based activity tracking is a priority.

The Oura Ring 4 is a sleek, minimalist smart ring designed for adults who want detailed health tracking without wearing a bulky device. It monitors over 50 health metrics, including sleep quality, heart rate, activity levels, stress, and women’s health, thanks to its advanced Smart Sensing technology. This makes it a strong choice for those looking for an all-around health and sleep tracker in a discreet form factor.

Battery life is impressive, lasting up to 8 days, which means less frequent charging and more continuous tracking. Its titanium build offers durability and comfort, and it’s water resistant, so you can wear it throughout the day and night, even in wet conditions. Compatibility is broad, working with both iOS and Android, and it syncs with popular health apps like Apple Health and Strava, enhancing its usefulness.

A consideration is the membership subscription tied to the app, which starts free for one month but costs $5.99 monthly or a prepaid annual fee. This subscription is necessary to access the full range of insights and data, which might be a drawback for some. The sizing is unique to Oura, requiring users to order a sizing kit to ensure the right fit, adding an extra step before purchase. The Oura Ring 4 is a smart choice for people wanting continuous, detailed health monitoring in an elegant and comfortable ring, while being mindful of the ongoing membership cost and sizing process.

The RingConn Gen 2 Air smart ring stands out with its extensive health tracking capabilities, including activity, sleep, heart rate, stress levels, and even menstrual cycles. Its AI-powered insights offer personalized health reports, enhancing the user experience. The ring's ultra-thin design and lightweight build (2.5g) ensure comfort and negligible interference in daily activities or sleep, making it an excellent option for continuous wear.

With a significant 10-day battery life and a swift 90-minute charge time, users won't need to worry about frequent recharges, making it practical for busy lifestyles. The IP68 waterproof rating adds to its versatility, allowing users to wear it during various water-related activities without concern for damage. Compatibility with both iOS and Android ensures broad usability, and the lack of subscription fees for standard app features is a notable advantage, providing great value.

However, the unique sizing requirement may pose an initial inconvenience, as users need to use a sizing kit for the perfect fit. Additionally, some users might miss the absence of built-in GPS for more detailed activity tracking. Despite these minor drawbacks, the RingConn Gen 2 Air smart ring is a robust and practical health monitoring tool, ideal for anyone looking to closely manage their wellness in a convenient and stylish form factor.
