Lawsuit alleges Oura Ring misleads on sleep-tracking claims
A Northern District of California class-action claims the Oura Ring cannot actually track sleep because it doesn’t measure brain activity, eye movements, or muscle tone, and instead relies on AI inferences from inputs it can’t verify. The suit, targeting Oura’s advertising, alleges fraudulent marketing and seeks more than $5 million for 100+ members under California’s Unfair Competition Law, False Advertising Law, and CLRA. Oura has not yet commented in the article.
