Oura Hit with Lawsuit over Allegedly Misleading Sleep-Tracking Claims
The complaint says Oura’s rings use AI guesses, not clinical sensors, while the company marketed up to 95% sleep-staging accuracy and sold rings for $300 and up.
- On Thursday, the Clarkson Law Firm filed a class-action lawsuit in California against Oura, alleging the company misled customers by claiming its smart rings offer "95% Sleep Staging Accuracy compared to clinical sleep lab" when actual results are closer to a coin flip.
- Despite marketing claims of "unparalleled accuracy," the complaint asserts that Oura rings rely on AI-generated estimates rather than clinical sensors because sleep cycles happen in the brain, not on a finger-worn device.
- Attorney Shireen Clarkson cited a 2025 study where Oura devices showed roughly 50% accuracy, while the company generated over $1 billion in revenue from nearly 3 million ring sales in 2025, according to the complaint.
- Responding to the lawsuit, Oura stated in a response to Gizmodo that its sleep-staging technology has been "validated and compared favorably in several studies against polysomnography," maintaining it transparently reports on its mechanisms.
- The suit seeks restitution for customers and an injunction to halt the alleged "unlawful and fraudulent" advertising of Oura rings, marking a significant legal challenge as the company faces growing scrutiny over wearable health-tracking accuracy.
