Oura Faces Class Action Over 95% Sleep Accuracy Claims on $300 Smart Rings

Summary
A proposed class action filed Aug. 20 in federal court in California accuses Oura of falsely marketing its rings as highly accurate sleep-stage trackers and seeks damages plus injunctive relief.
The complaint centers on ads touting “nearly 100%” accuracy, including a claim of 95% sleep-staging accuracy versus a clinical sleep lab, even though the rings start at $300 and cannot measure brain activity.
Plaintiffs say Oura instead relies on AI-based inference from finger data—described in the filing as little better than guesswork—while disclosures admitting the ring is not equivalent to polysomnography were buried in technical materials.
The suit targets the $11 billion company under fraud, warranty and California consumer-protection laws, arguing rivals either avoid such claims or use EEG-based headbands and home sleep-study devices with direct neurological sensors.
