Some smart rings need a subscription for full app access; others are sold without a mandatory data subscription. Oura requires an active Oura Membership for full access on Ring Gen3 and newer, but still shows a limited set of information without it. RingConn Gen 2, Ultrahuman Ring AIR, and Samsung Galaxy Ring are described in the cited manufacturer materials as not requiring a subscription for core data or insights. Those billing policies do not show that the rings offer equivalent features or measurement accuracy.

These are vendor statements about their own products, not an independent comparison. A no-subscription claim describes billing, not whether one ring is more accurate, clinically useful, or a substitute for medical care.

What you can still see in Oura without membership
Oura Member Care says that without an active membership, Gen3 and newer users can see three daily scores—Readiness, Activity, and Sleep—along with ring battery, basic profile information, app settings, and Explore content. Oura says Gen2 does not require membership. The limits described here apply to Oura’s stated membership policy, not to smart rings generally. Oura’s membership support page.
Some access paths differ: Oura says users can download their data through Membership Hub, but the Oura API is unavailable without an active membership. If membership is canceled without deleting the account, Oura says the data and account information remain saved and become accessible again if membership resumes. Its support page also says partial refunds are not available for canceled prepaid or annual plans after the complimentary month ends; check the current terms before relying on that policy.
