A lawsuit says Oura’s sleep stages are AI guesses with a coin flip’s odds

A class action lawsuit alleges that Oura's sleep staging accuracy claims are misleading, arguing the ring's AI-based estimates lack the precision of clinical sleep studies. Oura disputes these claims, standing by its research and accuracy. The case includes allegations of fraud and false advertising, coinciding with Oura's recent IPO filing and valuation as Europe's top consumer health hardware firm.
