Oura sleep tracking is under fire in a proposed class action lawsuit
Android Authority • • business
Key Points:
- A proposed class action lawsuit filed in California accuses Oura of overstating the accuracy of its sleep-stage tracking in its smart rings.
- The complaint alleges Oura relies on AI estimates from finger-based signals rather than clinical-grade sensors, challenging the company's claims of "unparalleled accuracy."
- The lawsuit highlights a 2025 study showing Oura rings correctly identified sleep stages only 53.18% of the time, contradicting the company's advertised accuracy rates of up to 95%.
- The Oura Ring 5, 4, and 4 Ceramic models are named in the lawsuit, which argues these devices lack the necessary sensors for clinical sleep staging.
- The suit seeks to halt Oura's allegedly misleading marketing claims and obtain restitution for customers who purchased the rings based on those claims.
