10 Best Wearable Sleep Trackers 2025 in the United States

The Oura Ring 4 is a smart ring designed primarily for detailed sleep tracking alongside fitness and health monitoring. It excels in accuracy by tracking over 30 biometrics, including heart rate and stress, thanks to its Smart Sensing technology that adapts to your body continuously. Its comfort is a strong point—the ring is made from lightweight titanium, offering durability and water resistance, making it suitable for all-day and night wear, even for sensitive skin. Battery life is impressive, lasting up to 8 days on a single charge, which means you can wear it without frequent interruptions for charging.

Data syncing is smooth through Bluetooth and it connects well with both iOS and Android devices, integrating with over 40 popular health and fitness apps, allowing you to see your metrics in one place. The user experience is enhanced by a dedicated app, though it does require a monthly or annual subscription after the first free month, which is something to consider. One potential drawback is the sizing process—Oura uses a unique sizing system, so you need to use their sizing kit before buying, which can feel a bit inconvenient compared to standard ring sizes. Also, the ring lacks a display, so all interactions and data views happen through the app.

This product is ideal for anyone looking for a discreet, stylish, and highly capable sleep tracker that also covers broader health insights. If you prefer a device with a screen or want to avoid subscription fees, this ring might not be the best fit.

The Samsung Galaxy Watch 8 (40mm) is a strong choice for anyone looking for a versatile wearable sleep tracker that also doubles as a full-featured smartwatch. It offers advanced sleep tracking with personalized coaching and bedtime guidance, which can help improve your sleep patterns over time. The watch’s slim and lightweight design means it’s comfortable to wear all night, which is key for accurate sleep data. Battery life is decent enough to last through a full day and night, so you won’t need to recharge constantly. It syncs well with Samsung’s Wear OS, making it easy to view your sleep and health data on your phone. Beyond sleep, it tracks heart rate, energy levels, running performance, and even stress through vascular load monitoring, giving a broader health picture. The improved user interface and built-in personal assistant add convenience and quick access to information.

While it is water-resistant and durable, the relatively small 1.3-inch screen might feel tight for some users, and those deeply invested in ultra-precise sleep tracking might find it less detailed compared to dedicated sleep trackers. Its price and complexity may be more than needed if you want a simple sleep-only device. For those seeking a stylish, multi-purpose wearable that supports sleep insights alongside fitness and daily tasks, the Galaxy Watch 8 is a fitting option.

The Apple Watch SE (2nd Gen) is a solid choice for anyone looking for a wearable sleep tracker that also offers a wide range of fitness and health features. Its sleep tracking is decent and benefits from integration with the Apple Health app, giving useful insights alongside heart rate monitoring and other health alerts. While it may not offer the deepest, most precise sleep analysis compared to some dedicated sleep trackers, it covers the basics well enough for everyday use. Comfort-wise, the 40mm size and lightweight aluminum case with a soft sport loop strap make it easy to wear overnight without feeling bulky.

Battery life typically lasts about 18 hours, so you’ll likely need to charge it daily, which can be a minor inconvenience if you want uninterrupted sleep tracking every night. Syncing data is seamless for iPhone users, with the watchOS interface being intuitive and user-friendly, making it easy to check your sleep stats and other health data. Additional health features such as heart rate notifications, crash detection, and workout tracking add extra value if you want more than just sleep information.

The watch is also swimproof, supporting water resistance up to 50 meters, so you don’t need to worry about sweat or rain. However, it’s less durable against rough impacts compared to specialized rugged devices. If you’re deeply invested in the Apple ecosystem and want a versatile device that combines sleep tracking with safety, fitness, and connectivity features, this Apple Watch SE is a great fit. But if your main focus is extremely detailed sleep data or longer battery life, other wearables might be better suited.
