Ultrahuman's smart ring, the Ring Pro, has finally received clearance to be sold in the U.S. market after a lengthy patent dispute with Oura, which had previously restricted Ultrahuman's sales of its Ring Air model. The Ring Pro, Ultrahuman's third-generation smart ring, features an impressive 15 days of battery life, significantly outpacing Oura's estimated 5 to 8 days. Additionally, Ultrahuman does not impose a subscription fee, unlike Oura, which charges $5.99 per month. The Ring Pro is priced at $479, with a separate charging case available for $100. While the Oura Ring 4 starts at $349, its higher-end finishes can reach $499. The Ultrahuman Ring Pro includes advanced features such as a redesigned heart rate sensor, a dual-core processor for machine learning, and 250 days of on-device health data storage. However, concerns remain regarding potential legal challenges from Oura over design similarities. With positive international feedback, Ultrahuman is poised to enhance its presence in the smart ring market.
