Product details

The Oura Ring 4 is the latest generation of Oura's smart ring. Made entirely from titanium, the smart ring employs the new smart sensing platform. It customises itself to you, captures your biometric values and offers you insights into over 30 biometric parameters, such as sleep, daily form, activity, heart health, stress and women's health. With up to eight days of battery life, the Oura Ring monitors your health and is so comfortable you'll hardly notice it's there.

Oura membership

In order to use all functions of the Oura Ring, a membership is required. Without a membership, the Oura Ring can only be used with limited functionality and you will not have access to the Oura API, but you can download all your personal data from Oura on the Web. With the Oura membership you get a detailed sleep analysis every morning and can track sleep, stress, activity, heart rate and much more. The first month of membership is free, after that it costs 5.99 USD per month. An annual membership is available for 69.99 USD. For more information: https://ouraring.com/de/membership

The Oura Ring 4 was fully convincing when tested and made it to number 1 on our best list. At the time of testing, no other smart ring can surpass the Oura in terms of features and operation. The sensors work reliably, both when measuring body functions and when tracking sports...

Stiftung WarentestSmart-Ringe im TestReleaseJune 2025

A smart ring measures pulse and skin temperature, counts steps and determines sleep quality, among other things. In this respect, it is similar to a smartwatch. But it is smaller, lighter - and less conspicuous. After all, not everyone likes to wear an occasionally vibrating mini screen on their wrist, preferring a conventional wristwatch - if they wear one at all...

Rank 4 out of 6Computer BildFitnesstracker im TestReleaseJune 2025

Heart rate measurement good
Sleep analysis good
Sports recording possible

Plan (5
99 euros per month) necessary
to use all functions

The Oura Ring 4 only offers the full scope with a plan. If you don't pay, you only get the daily analysis. The accurate heart rate measurement, good training recognition, detailed analysis and good sleep recording all speak in favour of paying. It would be nice to have a charging case to charge the ring without a cable.

Plan (5.99 euros/month) required
to use all functions

The Oura Ring 4 can do the same as the Ring 3, but is housed in a slim titanium casing. The battery life is good and the ring can be conveniently charged on the pad - but only with a permanent power supply. The good and detailed analysis actually speaks in favour of Oura. But it is only available with a plan (5.99 euros/month)...
