Get This Price

For just $399, down from its list price of $499. That is $100 below what this ring has averaged over the last six months. The Ceramic Tide finish rarely sees cuts this deep, making this one of the better deals on Oura's latest generation tracker.

What You're Getting

The Oura Ring 4 packs Smart Sensing technology that adapts to your body for accurate readings across sleep, activity, stress, heart health, and women's health. It tracks over 50 health metrics without a screen or vibrations, letting you stay present while it works in the background.

Battery life stretches up to 8 days between charges. A first month of Oura Membership is included (new members only), then $5.99/month after that. The ring is also HSA/FSA eligible. Proper sizing matters here -- Oura uses its own sizing system, not standard ring sizes, so use the sizing kit before committing.

Who This Is For

Best for: health-tracking enthusiasts who want 24/7 data without wearing a watch. The Ceramic Tide finish appeals to anyone who prefers a lighter, more jewelry-like look over the dark titanium options.

Skip this if you are already on Gen 3 and happy with it -- the upgrades are iterative, not revolutionary.

The Caveat

The Oura Membership is required after the first free month to access detailed insights. Factor that $5.99/month into the long-term cost.

Also, the size 5 option here runs small -- double-check your fit with the sizing kit.

Final Verdict

A $100 discount on a ring that rarely dips below $498 makes this a straightforward buy if you want the Ceramic Tide color. Grab it at Amazon before inventory shifts.
