10 Best Activity Trackers 2026 in the United States

The Oura Ring 5 is a smart ring designed to track your health and activity in a very compact, comfortable form. It's the world’s smallest smart ring, made from durable titanium and about 40% smaller than its predecessor, making it very discreet to wear. It focuses heavily on sleep tracking and health monitoring, capturing data on your heart rate, stress, metabolic health, and women’s health metrics. While it doesn’t have built-in GPS, it pairs with your phone via Bluetooth and integrates with many fitness apps, which can supplement location tracking.

Battery life is solid, lasting between 6 to 9 days on a single charge, so frequent recharging isn’t necessary. The ring is water-resistant, suitable for everyday wear without worry. The Oura Ring 5 requires a subscription after the first free month, providing access to personalized insights and an AI health advisor that helps guide you toward better sleep and energy management. One important note is that sizing is unique and essential for comfort and accuracy, so using the sizing kit before buying is necessary.

Its display is minimal since it’s a ring, focusing on data collection rather than interactive screens. This makes it ideal for users who want a low-profile device that tracks detailed health metrics, especially sleep, rather than a full-featured GPS activity tracker. For those seeking a discreet, easy-to-wear tracker with excellent sleep and health insights without built-in GPS, the Oura Ring 5 represents a strong option.

The Oura Ring 4 is a sleek, gold-colored smart ring designed to track a wide range of health metrics, including heart rate, sleep, activity, stress, and women's health data. It excels in sleep tracking and continuous monitoring thanks to its Smart Sensing technology, which adapts to you throughout the day and night. The ring is water resistant up to 100 meters, making it safe for swimming and everyday wear. Battery life is impressive, offering up to 8 days of use on a single charge, which means less frequent charging compared to many wrist-based trackers. However, the Oura Ring 4 does not have a built-in display or vibration alerts, so all data and notifications are accessed through the companion app on your smartphone. GPS functionality is supported but only through your phone’s GPS, not built directly into the ring, so location-based tracking depends on carrying your phone. Compatibility is broad, working with both Android and iOS devices via Bluetooth.

The ring comes in a unique sizing system, so it’s important to use the provided sizing kit before purchase to ensure a comfortable fit. Additional features like menstrual cycle tracking and daily workout memory add value, especially for users interested in women’s health and overall wellness. The monthly membership subscription provides enhanced insights but is optional after the first free month. Users focused on detailed health and sleep data in a discreet form factor will find the Oura Ring 4 well suited to their needs, though those seeking real-time feedback on their wrist or built-in GPS might find it less convenient.

The Oura Ring 4 is a smart ring designed to help you monitor your health and activity with a focus on sleep and wellness rather than detailed workout tracking. It offers accurate heart rate monitoring and tracks over 50 health metrics including sleep quality, stress, body temperature, and women’s health features like menstrual cycle tracking. While it doesn’t have built-in GPS, it connects easily to your smartphone via Bluetooth and works with both Android and iOS devices.

The ring is lightweight, made of durable titanium, and water resistant up to 100 meters, so you can wear it during swimming or in the shower without worry. One standout feature is its long battery life—lasting up to 8 days on a single charge—which is longer than many other activity trackers, and it charges fully in about 80 minutes. It does not have a screen, meaning you won’t see stats directly on the ring but will use the Oura app to review your data. The sizing is unique, so you’ll need to order a sizing kit to get the best fit before buying.

The included membership service gives personalized insights, but it requires a monthly subscription after the first free month. For those mainly interested in detailed GPS tracking or an active display, this ring may not be the best fit. However, if you want a comfortable, stylish, and water-resistant tracker focused on sleep, recovery, and long battery life, the Oura Ring 4 presents a compelling option.
