Oura Sued Over Allegedly Misleading Sleep Tracking Accuracy Claims
Oura faces a proposed class action alleging its $300 smart rings misstate sleep staging accuracy, including a recent 95% claim versus clinical lab tests.
Summary
A proposed class action filed Thursday by Clarkson Law Firm in San Francisco accuses Oura of deceptively marketing smart rings costing $300 and up as accurate sleep trackers. The complaint alleges Oura cannot measure the physiological signals required to assess sleep quality or identify the four sleep stages because those measurements require scalp electrodes and eye sensors in clinical settings. It says the rings instead produce AI estimates with roughly a coin flip’s chance of being correct, despite Oura advertising 79% measurement accuracy and, more recently, 95% sleep staging accuracy against clinical sleep labs.
The suit follows years of users questioning Oura’s sleep cycle detection, including reports that rings rated sleep as optimal when wearers felt they had slept poorly. Ryan Clarkson, Clarkson Law Firm’s co-founder and managing partner, said inaccurate health guidance could change users’ behavior. The complaint seeks restitution and an injunction requiring Oura to stop advertising capabilities it allegedly cannot deliver. Oura had not responded to TechCrunch’s request for comment when the article was published on August 21, 2026.
