I’d be lying if I said I wasn’t a little obsessed with tracking my health.

Ever since I started wearing the Oura Ring 4, I’ve been able to better understand and optimize my sleep, activity and recovery. It’s helped me spot patterns in my daily habits, improve my stress levels and even catch signs that I might be getting sick before symptoms fully set in.

I’ve tested several smartwatches and fitness trackers over the years, but the Oura Ring remains the one wearable I consistently recommend. Its sleek, minimalist design, long battery life and impressively easy-to-understand health insights make it one of the most seamless devices I’ve incorporated into my life. Both the titanium and ceramic designs are easily mistaken for jewelry.

And best of all: right now, the Oura Ring 4 is $100 off ahead of Amazon Prime Day, which runs from June 23 to June 26. Oura Ring discounts this steep are rare, making it an excellent opportunity to pick up the viral wearables for way less.

Earlier this month, the brand released the lighter, slimmer Oura Ring 5, which starts at $499. But if you’re looking to save while still getting access to Oura’s standout health-tracking features, I wouldn’t overlook this deal on the previous-generation model.

The Oura Ring 4 uses Smart Sensing technology to monitor more than 50 health metrics, from sleep quality and heart rate to stress, activity, and recovery. It also offers women’s health insights, including cycle tracking and period predictions, all accessible through the Oura app.

Users rave that it’s extremely durable and built for everyday wear.

“I’ve been using the Oura Ring 4 daily, and I’m very impressed with its design and functionality. It’s lightweight, comfortable to wear all day, and doesn’t feel bulky at all,” one reviewer shared. “The health tracking features are very detailed, especially sleep and activity insights, which have helped me better understand my daily habits. The app is easy to use and provides clear information.”

With up to eight days of battery life, the ring delivers continuous tracking without the need for frequent charging. It also comes with a charger and a USB-C cable.

New users also get their first month of Oura Membership included. After that, the subscription costs $6/month and unlocks the app’s full suite of health, sleep and recovery insights.
