Is there a subscription fee for using the Oura Ring?

The Oura Ring itself does not come with a mandatory subscription fee for basic use; once you purchase the ring, you have access to the essential features and the companion app to track your activity, sleep, and readiness without an ongoing cost. However, for enhanced insights and more in-depth analysis, Oura offers a premium membership subscription called Oura Membership which users can opt into for additional content, features, and services beyond what's available in the basic package. The decision to subscribe is entirely optional depending on whether one wants to take advantage of the extra benefits offered by the membership.
