Lawsuit Alleges Oura Sleep Tracking Has ‘Coin Flip’ Accuracy

What happened

• A class action lawsuit has been filed against Oura alleging that its sleep-tracking mechanisms use faulty AI-based inference as reliable science.
• The plaintiff claims that the Oura Ring lacks necessary sensors, such as brain wave and eye movement data, to accurately measure the neurological activity that defines sleep stages.
• The complaint states that Oura’s AI models are essentially doing guesswork based on improper inputs.

Why it matters for me

This lawsuit raises serious questions about how wearable devices translate biometric signals from the wrist or finger (like heart rate and body temperature) into accurate sleep diagnostics. The core argument is that sleep happens in the brain, not just on the finger. If proven true, this could shake up the billion-dollar health wearables industry.

What to remember

• The lawsuit cites a Nature study which found the smart ring achieved only “limited accuracy” in sleep staging, with a 53% success rate.
• The plaintiff, Madison Surber, claimed she paid an “unwarranted premium” for a device that did not meet its marketing promises.
