A lawsuit says Oura’s sleep stages are AI guesses with a coin flip’s odds
A lawsuit alleges Oura's sleep staging is inaccurate AI estimates rather than measurements.Summary
A proposed class action filed in San Francisco alleges that Oura's sleep staging is generated by AI estimates rather than measurement, naming Finnish parent Oura Health Oy as a defendant. The complaint specifically challenges Oura's advertised "95% Sleep Staging Accuracy compared to clinical sleep lab," arguing that a finger-worn device cannot substantiate this claim. The filing describes Oura's sleep stages as "AI-generated guesses" with roughly "a coin flip's chance" of being right, citing a study that found overall sleep stage classification accuracy of 53.18%. Oura rejects this characterization, stating it "stands behind our science, research, and accuracy claims." The case carries seven counts, including fraud by misrepresentation and breaches of California's Unfair Competition Law and False Advertising Law.
