Keeping track of fitness goals and gains can seem overwhelming, but one small piece of jewelry makes logging your health stats effortless.

Whether you’re a marathon runner or simply dedicated to doing laps around your block, chances are you’re familiar with the Oura Ring. I’ve never been one to obsess over health data, but the analytics this product delivers are irresistibly interesting.

The Oura Ring 4 Smart Ring is on sale for $50 off following October Prime Day — but only for a limited time.

I was fascinated by the 50 health metrics it provides, including sleep, activity, stress, heart health and women’s health details. A Smart Sensor adapts to your body to deliver accurate personalized data, no matter what time of day.

The titanium ring is so lightweight, you’ll forget you’re wearing it. The battery lasts for eight days before you even need to take it off to charge.

Plus, it’s water-resistant, ideal for those who get extra sweaty during workouts or want to go for a swim.

To secure an ideal fit, you’ll receive an Oura Ring 4 Sizing Kit in the mail ahead of the actual ring being delivered. The first month of the membership is free for new members, and just $5.99/mo afterwards.

The smart ring syncs up to health apps you may already have on your phone, including Apple Health, Google Health Connect, Natural Cycles, Flo and Strava.

I spend all week browsing Amazon for hot deals, and I have rarely seen Oura available at a discount. Shop Oura Ring 4 Smart Ring now at $50 off for a limited time.
