Amazon Prime Day is here, giving Prime members exclusive access to deals across categories like sneakers, vacuums and smartwatches. If you’ve been thinking about getting a smart ring, the Oura Ring is currently on sale, matching its lowest price ever. It’s one of my favorite smart rings, and a great fit for anyone who wants to do health, sleep and fitness tracking without a bulky smartwatch.

The Oura Ring is a smart ring that tracks loads of health metrics — think heart rate, body temperature, stress levels, blood oxygen, steps and more. It automatically detects sleep, naps, and some exercises like walking and running, plus you can manually start and stop dozens of different kinds of exercises through the Oura app. The app keeps track of all your metrics, and summarizes them into sleep, activity, stress and readiness scores and reports. It has a seven-day battery life, which means you don't have to always worry about charging it up.

The Oura Ring Gen3 essentially requires a $5.99 monthly subscription. You can learn more in my Oura Ring Gen3 review.

The Oura Ring 4 is the brand’s latest model. It has a longer eight-day battery life, a wider range of sizes and a fully titanium build with recessed sensors nearly flush with the ring’s interior. In my experience, it has also improved software that leads to slightly more accurate health data. Like the Gen3, the Oura Ring 4 requires a $5.99 monthly subscription. You can learn more in my Oura Ring 4 review.

I tested the Oura Ring 4 for over two months after the brand sent me a sizing kit and ring sample for review. The Oura Ring Gen 3 was already my favorite smart ring on the market. The Oura Ring 4’s hardware and software improvements help cement it as the best smart ring you can buy right now.

The Samsung Galaxy Ring is a great Oura Ring alternative if you use a lot of Samsung devices and want a subscription-free experience. It works seamlessly with Samsung Galaxy phones and Galaxy watches, and tracks similar metrics to Oura.

If you have an Apple watch, the latest Apple Watch SE makes for a great health, sleep and fitness tracker. If you like the minimalism of a smart ring, you can always turn off all notifications and alerts in your settings menu.
