10 Best Smart Rings 2025 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 Milavan Smart Health Ring is a slim, stylish fitness tracker designed for both men and women who want continuous health monitoring without the bulk of a wristband. It measures heart rate, blood oxygen, and blood pressure automatically every 30 minutes, providing detailed health insights throughout the day. The ring also tracks sleep stages, including deep and light sleep, helping you understand your rest quality. With 8 sports modes like running, cycling, and yoga, it covers a variety of activities, capturing steps, calories, distance, and heart rate during workouts.

The ring is compatible with both iPhone and Android devices, making it widely usable. It lasts 3 to 5 days on a quick 1-2 hour charge, which is decent for a device this small. The IP68 waterproof rating means it can handle sweat and rain, though it's best not to submerge it for long periods. In terms of comfort, the ring is very thin (just 2mm) and polished inside, which suits most fingers and sports activities. However, sizing is important, so measuring your finger before buying is recommended to avoid fit issues. The device also offers extras like remote photo control via the app and a care mode to share health data with family or friends.

The battery capacity is quite small, so heavy use might require more frequent charging. While it provides comprehensive health data, it relies on your smartphone’s GPS for tracking routes, meaning it depends on your phone during outdoor activities. The smart ring does not require a subscription fee, which is a benefit compared to some competitors. This ring suits fitness enthusiasts and health-conscious users who want a discreet, multipurpose tracker with solid health features and decent battery life, but it may be less suitable for those who prefer a device with built-in GPS or longer battery endurance.

The BIEMHA Smart Health Ring offers a comprehensive set of health tracking features, including heart rate, blood oxygen, blood pressure, step counting, and sleep monitoring. Its sensors provide continuous monitoring every 30 minutes, which is great for users wanting detailed health insights. The ring is lightweight and designed for comfort, making it suitable for daily wear, and its silver color adds a simple, sleek look. One standout feature is its impressive waterproof rating of up to 80 meters, so you can wear it while swimming or during intense workouts without worry.

Battery life is solid, lasting 7 to 10 days on a single charge, with the included smart charging case extending usage up to 30 days. This means less hassle from frequent charging. Compatibility is good as it works with both iPhone and Android devices via Bluetooth, and there are no extra subscription fees to enjoy its features, which is a nice plus for budget-conscious users.

The ring does not include GPS, so if you need location tracking during outdoor activities, this might be a limitation. Also, the screen is very small (1 millimeter), so it’s not designed for interacting with apps directly but more for passive data collection synced through your phone. The manufacturer emphasizes sizing before purchase, which is important to ensure comfort and avoid returns. The BIEMHA Smart Ring is a well-rounded fitness tracker suited for those who want continuous health monitoring in a compact, durable, and waterproof design without ongoing costs. It’s especially good for users focused on tracking vital signs and sleep, although those needing GPS or a larger display might want to consider other options.
