A proposed class action lawsuit has accused smart ring maker Oura of deceiving consumers about the accuracy of its sleep tracking features. The lawsuit, filed on Thursday by Clarkson Law Firm in San Francisco, alleges that Oura rings are unable to measure any of the physiological signals needed to assess sleep quality or determine sleep stages, and instead rely on AI-generated estimates that have “a coin flip’s chance of being correct,” according to the complaint.
The complaint claims Oura marketed its rings, priced at $300 and up, as being able to see what only a hospital sleep lab can see, including the four stages of sleep. It says Oura advertised “built for accuracy” and “unparalleled accuracy,” and told customers the rings could achieve 79% accuracy, later claiming 95% sleep-staging accuracy compared with clinical sleep labs.
The lawsuit follows years of user complaints online about sleep accuracy, with some saying they felt they slept poorly but were told their sleep had been optimal. Ryan Clarkson, co-founder and managing partner at Clarkson Law Firm, said in a press release: “When people rely on a device to guide decisions about their health, misinformation cannot be tolerated.”
The complaint seeks to stop Oura from falsely advertising its wearables, injunctive relief, and restitution for consumers who purchased the products based on the allegedly false claims. Oura did not immediately respond to a request for comment.
