10 Best Sleep Trackers 2025 in the United States

The Apple Watch Series 10 (GPS 46mm) offers a compelling sleep tracking experience wrapped in a versatile smartwatch. Its accuracy benefits from advanced sensors like the electrical heart sensor and third-generation optical heart sensor, which help provide detailed sleep data including sleep stages and potential signs of sleep apnea. The watch's lightweight and thinner design makes it comfortable enough to wear overnight without much disturbance. Battery life supports about 18 hours of normal use, which means you’ll typically need to charge it daily; however, fast charging can rapidly top up the battery, including a quick charge feature that can support a full night of sleep tracking with just 8 minutes of charging.

Data syncing is seamless but requires an iPhone (Xs or later) running iOS 18 or higher, so compatibility is limited to Apple ecosystem users. The watch also syncs with the Health app for comprehensive insights and supports notifications and other smart features right from your wrist. Additional health features like ECG, cycle tracking, and heart rate notifications add value beyond sleep tracking. Its ease of use is enhanced by a bright, always-on Retina display and intuitive controls like the digital crown and Siri integration.

The relatively short all-day battery life means you’ll need to plan charging times carefully, especially if you want overnight sleep tracking plus daytime use. Also, it’s a higher-cost option best suited for those who want an all-in-one health and fitness companion rather than a simple dedicated sleep tracker. For users deeply invested in the Apple ecosystem seeking reliable sleep insights alongside fitness and safety features, the Series 10 presents a strong choice.

The Oura Ring 4 is a sleek, lightweight smart ring designed to track sleep, activity, heart rate, stress, and more with strong accuracy. Its Smart Sensing technology adapts to your body, offering detailed insights around the clock. Comfort is a priority here, as the ring is made from durable titanium, is water resistant, and designed for 24/7 wear without feeling bulky.

Battery life is impressive, lasting up to 8 days on a single charge, so you won’t need to recharge it frequently. Syncing is easy via Bluetooth, and it works smoothly with both iOS and Android devices, integrating with popular health and fitness apps like Apple Health and Strava. The sizing system differs from standard ring sizes, so you’ll need to use their sizing kit before purchasing to ensure a good fit. The Oura Ring requires a membership subscription after the first free month, which some users might find inconvenient.

Although it doesn’t have a GPS, this isn’t a big issue for a sleep-focused device. The ring’s discreet design makes it a stylish option for those who want detailed sleep and health tracking without wearing a bulkier device. The touchscreen input is minimal but functional, keeping things simple. If you’re looking for a comfortable, accurate sleep tracker with long battery life and strong app compatibility, the Oura Ring 4 is a strong choice, but be mindful of the sizing process and ongoing membership costs.

The Oura Ring 4 is a modern sleep tracker designed to be worn on your finger, offering a unique and stylish approach to monitoring your sleep and fitness. It's small and lightweight, making it comfortable to wear throughout the day and night. This ring tracks your heart rate and activities, providing insights into your well-being.

One of its standout features is its impressive battery life, lasting up to 8 days on a single charge, which means less frequent recharging compared to other wearables. The ring comes with Bluetooth connectivity, ensuring that your data syncs smoothly with your smartphone. However, it does not have built-in GPS, which could be a downside if you’re looking for detailed location tracking for outdoor activities.

The Oura Ring 4 is user-friendly, with a simple set-up process and a straightforward interface, making it accessible even for those who aren’t tech-savvy. Some users might find the price point a bit high for a ring, and the sizing process requires using a sizing kit before purchasing.
