Oura announced the latest version of their health and fitness-focued smart ring today – the Oura Ring 5:

SAN FRANCISCO–(BUSINESS WIRE)–ŌURA, maker of the world’s leading smart ring, today announced Oura Ring 5, the smallest smart ring in the world. Built on more than twelve years of industry-leading innovation, Oura delivers its most advanced health sensing and insights in a more comfortable and compact form than ever before. Crafted from lightweight, non-allergenic titanium, Oura Ring 5 goes beyond tracking. Oura pairs its most innovative hardware yet with new software that moves beyond tracking to action—spanning preventative health, metabolic insights, live activity, and more to deliver the most complete member experience yet.

According to the company, the Oura Ring 5 is “40 percent smaller, with next-generation sensing for best-in-class accuracy, week-long battery life, and powerful new software features that connect clinical history with real-time biometrics to create a more comprehensive, predictive view of health.”

The Oura Ring 5 is available for pre-order now, in a variety of colors / finishes, with prices starting at $399.

I purchased an Oura Ring 4 back in October, 2024 but ended up returning it a short while later. While I like the idea of wearing a smart ring, I also wear an Apple Watch and found that I already had much of the data that the Oura Ring provided.

That said, the Oura Ring’s sleep tracking was a nice feature to have, especially as I don’t generally wear my Apple Watch to bed. I did find the Oura Ring 4 to be a bit on the thicker side, so I am interested in seeing how the smaller 5th generation ring looks and feels.
