Oura Ring Dupes: 6 Smart Ring Alternatives Compared

What to compare with an Oura Ring

These rings are alternatives, not copies. None of them is made or endorsed by Oura, and none of the makers says its ring matches the Oura Ring. The differences below come from the makers' pages and the Amazon listings.

• Subscription. Oura says its membership is needed to unlock all of the daily insights: "purchasing, activating, and consistently wearing an Oura Ring is the only way to unlock access" to them, and "new members get their first month free." The Oura Ring 4 listing says the first month is included and a monthly fee follows. The RingConn, Ultrahuman, Amazfit and Samsung listings each say no subscription is required, though the RingConn Gen 2 Air listing limits that to standard features.
• Battery claim. These are the makers' own "up to" figures, and real use varies. Listings state up to 8 days for the Oura Ring 4, up to 7 days for the Samsung, up to 10 days for the RingConn Gen 2 Air, 14 days for the RingConn Gen 3 and up to 15 days for the Ultrahuman Ring PRO. Oura says battery life depends on ring size and lifestyle.
• Sensors and features. All of these rings track sleep and heart rate, as the listings describe. Beyond that the lists differ: the Amazfit listing mentions an EDA sensor for stress, the Ultrahuman listing mentions skin temperature, and the RingConn Gen 3 listing mentions vibration alerts. Read any numbers as general information, not a diagnosis.
• Sizing. Ring sizes do not match jewelry sizes. Oura, RingConn, Amazfit, Ultrahuman and Samsung all point you to a sizing kit before you buy. Samsung says the kit lets you try on a sample ring "for more than a day." A ring that is too loose or too tight may track poorly or feel uncomfortable.
• Phone and app. Every ring needs its own app. The Oura Ring 4 listing says it works with Android and iOS, and Samsung says select Galaxy AI features require a compatible Samsung Galaxy phone. Check your phone against the listing before you order.
• Charging. Several rings ship with a charging case, including the RingConn and Ultrahuman models. Oura says its ring typically charges in 20-80 minutes depending on the battery level.

Smart rings give general wellness information and do not replace a doctor. If a reading worries you, or you have a health condition, ask your doctor or pharmacist what the numbers mean for you.

Frequently asked questions

Is there an Oura Ring that does not need a subscription?

Oura says its membership is how you unlock all of the daily insights, and new members get their first month free. The alternatives on this page each say no subscription is required, though the RingConn Gen 2 Air listing limits that to standard features.

Are these rings copies of the Oura Ring?

No. They are alternatives from other makers, each with its own sensors, app and sizing. None is made or endorsed by Oura, and no maker on this page says its ring matches Oura's.

How do I find my smart ring size?

Order the maker's sizing kit. Oura, RingConn, Amazfit, Ultrahuman and Samsung all say their sizes differ from jewelry sizes. Samsung says to try on a sample ring for more than a day before you order.

Which smart ring has the longest battery claim?

Among these listings, the Ultrahuman Ring PRO lists up to 15 days, followed by the RingConn Gen 3 at 14 days. These are the makers' own claims and real use varies with ring size and settings.

Can a smart ring tell me if I am sick?

No. These rings give general wellness information. If a reading worries you or you have a health condition, ask your doctor what it means for you.

How we chose

This guide is desk research. We read the Oura membership and Oura Ring 4 pages, RingConn, Ultrahuman and Samsung pages, and the Amazon listing for each ring. We did not test any of these products; the notes describe what each maker or listing says, not how a ring performs.

At time of writing (November 9, 2026), every "Check price on Amazon" button on this page went to an exact Amazon listing that was new and in stock. Sellers, sizes and colors change, so confirm the details on the listing before you buy.

A dupe here means an alternative, never a copy. None of these products is made or endorsed by Oura. We could not read an Amazfit page, so the Amazfit notes come from its listing only.
