Before you buy
Where to buy the Oura Ring 4
Oura sells the Ring 4 at ouraring.com, and MetaOriental links there rather than selling it. The Oura Ring 4 costs $349.00. Oura's full insights run on a membership, so price the subscription alongside the ring rather than after it.
Who the Oura Ring 4 is for
The Ring 4 is for people who want sleep, readiness and recovery data without wearing a watch to bed. It measures 7.9 mm wide and about 2.88 mm thick, weighs 3.3 to 5.2 g depending on size, and carries red, infrared and green LEDs plus a digital temperature sensor. Oura has the longest track record of any smart ring, which matters for how far back your trends go.
Is the Oura Ring 4 worth $349.00?
The Ring 4 is the most established smart ring and the data quality reflects that, which is what $349.00 buys over newer rivals. The subscription is the real consideration: over three years it can approach the price of the ring again, and rings such as AIVELA sell without one. Buy Oura for the track record and the app; buy a subscription-free ring if the monthly fee is the sticking point.
