Oura Ring Lawsuit Questions Whether Finger Sensors Can Truly Gauge Sleep Stages

Дата публикации: 21-08-2026 23:32:06

A new class-action lawsuit accuses Oura of misleading buyers about its rings' ability to accurately track sleep stages, claiming the devices rely on AI inferences rather than direct brain measurements and overstate accuracy at 79-95%. Plaintiff Madison Surber says she would not have paid $513 for her Ring 4 had she known the limits. The case could reshape how wearables market health insights.
