Oura Ring Accuracy Under Fire in Lawsuit
21 Aug
Summary
- Lawsuit claims Oura's sleep tracking is highly inaccurate.
- A study found Oura overestimated REM sleep by 31 minutes.
- The suit seeks to stop Oura's alleged fraudulent advertising.
A proposed class action lawsuit filed on August 20, 2026, accuses Oura of deceiving customers about the accuracy of its popular smart ring's sleep-tracking capabilities. Clarkson Law Firm alleges that Oura has falsely advertised its technology, suggesting it is no more accurate than a random guess.
The legal complaint references user complaints and scientific studies, including one published in Nature which found Oura rings overestimated REM sleep by 31 minutes over 45 nights. The suit asserts that Oura's inaccurate data misleads consumers about the product's value.
Plaintiffs are requesting Oura cease its allegedly unlawful advertising and marketing, and provide restitution to current customers. The future course of the lawsuit remains uncertain, including the possibility of other Oura ring owners joining.
PCMag's own review of a recent Oura Ring model found its sleep data to be consistent with rival devices like the Fitbit Air and Apple Watch Ultra 3.
