  • Oura faces a proposed class action lawsuit filed by Clarkson Law Firm in San Francisco.
  • The complaint alleges the rings cannot measure physiological signals needed for sleep assessment.
  • Oura previously claimed up to 95% sleep-staging accuracy compared to clinical sleep labs.

Smart ring manufacturer Oura is facing a proposed class action lawsuit accusing the company of deceiving consumers regarding the precision and accuracy of its sleep-tracking features.

The lawsuit was filed on Thursday in San Francisco by Clarkson Law Firm. According to the complaint, Oura rings are incapable of measuring any of the physiological signals required to evaluate sleep quality or determine specific sleep stages.

The legal filing further alleges that the rings instead rely on AI-generated estimates, which carry a coin flip's chance of being correct. This follows years of user frustration shared online, with customers questioning the device's sleep-monitoring reliability.

This legal challenge highlights the growing scrutiny facing wearable health technology. As consumers increasingly rely on biometric data for wellness decisions, unsubstantiated claims of clinical-grade accuracy can expose companies to significant legal risks and set a precedent for transparency in the health-tech sector.

Several users previously reported feeling poorly rested despite the app telling them their sleep was optimal, while others expressed doubts over the device's ability to accurately detect sleep cycles.

95%Claimed sleep-staging accuracy compared to clinical labs

Despite these reported inconsistencies, the complaint alleges that Oura marketed its wearable as built for accuracy with unparalleled precision. The company reportedly told customers its rings achieved 79% measurement accuracy and later claimed a 95% sleep-staging accuracy compared with clinical sleep labs.

Oura did not immediately respond to TechCrunch's request for comment. The lawsuit seeks to stop Oura from continuing to misrepresent its products and asks for restitution for consumers who purchased the wearables based on those claims.
