Oura Faces Class Action Over AI Sleep-Tracking Claims

Oura has made sleep analysis a central selling point of its smart ring, using optical, temperature and movement sensors alongside AI models to estimate wakefulness, light sleep, deep sleep and REM sleep. Clinical sleep staging typically relies on signals including brain-wave activity, making the accuracy and marketing of consumer wearables an increasingly important issue as users rely on them for health-related insights.

A proposed class action alleges that Oura misled consumers by presenting its ring as capable of accurately tracking sleep stages even though it cannot directly measure brain activity inside the skull. The complaint says the device instead uses AI to infer sleep stages from indirect physiological signals and that Oura overstated its capabilities.
