10 Best Smart Rings 2025 in the United States

The Oura Ring 4 is a sleek, silver smart ring designed for 24/7 wear, made from durable titanium that’s also water resistant, making it comfortable and long-lasting. It excels at health tracking, monitoring over 30 biometrics including sleep quality, heart rate, stress levels, and women's health data with high accuracy thanks to its Smart Sensing technology. This makes it a great choice if you want detailed insights into your wellness and recovery.

The ring’s battery lasts up to 8 days, which is convenient as you won’t need to charge it frequently. It connects via Bluetooth and is compatible with both iOS and Android devices, syncing with popular health and fitness apps to keep your data organized. One important note is the membership subscription required after the first free month to access the app’s full features, which adds an ongoing cost. The ring does not have GPS, so it’s less suited for tracking outdoor activities like running routes.

Additionally, sizing is unique and requires ordering a sizing kit first, which adds a step before purchase. If you’re looking for a discreet, stylish smart ring focused on accurate sleep and health tracking with good battery life and app support, the Oura Ring 4 is a strong contender. However, the subscription model and lack of GPS might be downsides depending on your needs.

The RingConn Gen 2 Air is a sleek and lightweight smart ring designed to track various health metrics like sleep, heart rate, stress, blood oxygen, physical activity, and menstrual cycles. Thanks to its AI-powered insights, it doesn’t just collect data but also gives you personalized health tips, which can be a big help for improving daily habits. One of its standout points is the comfortable, ultra-thin design that weighs only 2.5 grams, meaning you can wear it all day and night without feeling it or it getting in your way during workouts or sleep.

The battery life is impressive, lasting up to 10 days on a single charge that takes just about an hour and a half, so you won’t be constantly recharging it. It is also very durable and water-resistant, with an IP68 rating that lets you wear it in the shower, swimming, or even diving to decent depths, which adds to its versatility. The ring works with both iOS and Android devices, and you don’t need to pay a subscription fee for the standard tracking features, which is a nice bonus.

Sizing is a bit unique for this ring, so you’ll need to order a special sizing kit to ensure a perfect fit, which might be an extra step some users find inconvenient. Also, it lacks built-in GPS, so if you want detailed location tracking during activities, this may not meet that need. The RingConn Gen 2 Air suits people looking for a stylish, no-fuss health tracker that covers the basics well, especially for continuous monitoring with good battery life and water resistance. Those needing advanced sport tracking or simpler sizing might want to consider these points before deciding.

The Oura Ring Gen3 Heritage is a sleek and modern smart ring that stands out in the health tracking category. One of its significant strengths is its comprehensive health tracking features. It monitors sleep, heart rate, activity, and stress, giving users a deep insight into their overall wellness. With more than 20 biometrics tracked, it's designed to provide accurate health data, making it particularly appealing for fitness enthusiasts or anyone keen on improving their health habits.

Battery life is another plus, as it lasts between 5 to 7 days on a single charge, which means less hassle with frequent recharging. The ring is also durable; made from titanium, it's lightweight, non-allergenic, and water-resistant, enhancing comfort for everyday wear, whether during workouts or while sleeping.

Compatibility with both iOS and Android devices is a major advantage, allowing users to sync it with popular apps like Apple Health and Strava, making it a versatile choice for those who use various health platforms. However, there are some drawbacks to consider. One notable aspect is the required Oura Membership for accessing the full range of features, which comes with a monthly fee after a free trial month. This ongoing cost may not be ideal for all users. Additionally, the sizing can be tricky since Oura Ring sizes differ from standard ring sizes, requiring you to purchase a sizing kit beforehand, which might be inconvenient for some.
