Oura’s biggest competitor is officially bringing its new flagship smart ring model, the Ultrahuman Ring Pro, to the U.S. market. Not only does it crush the Oura Ring 4 in terms of battery performance, but it’s also completely subscription-free.
As a reminder, Ultrahuman and Oura have serious beef with one another. Back in October 2025, Oura successfully forced Ultrahuman to pull the brand’s then-flagship model from the U.S. market due to alleged infringements of Oura’s intellectual property. As of writing, the Ultrahuman Ring Air remains unavailable (directly) for U.S. customers.
