The short version

Reviewers broadly agree that the Oura Ring 4 is the smart ring to beat. Its lighter, fully rounded design is more comfortable, redesigned sensors reduce data gaps as the ring rotates, and the organized app turns activity, sleep and stress data into useful guidance. The catch is cost: premium finishes are expensive, and most of the worthwhile tracking requires an ongoing membership.

What reviewers loved

  • Redesigned sensors maintain more consistent readings as the ring rotates, helping avoid gaps in activity and sleep data.
  • The lighter, fully rounded design removes the internal sensor bumps and feels more comfortable than earlier Oura models.
  • The well-organized app converts sleep, activity and stress measurements into readiness, activity and sleep scores with personalized guidance.
  • Critics report strong sleep and women’s-health tracking, including period prediction based on temperature trends.
  • Weeklong battery life and support for both Android and iOS make it easier to live with than a phone-locked wearable.

What held it back

  • The $349 / £349 starting price is high, while finishes such as gold rise to $499 / £499.
  • A $5.99 / £4.99 monthly membership is required for the high-end tracking features.
  • Workout information is less detailed than the data supplied by wrist-based fitness trackers.
  • Step counts and calorie estimates can be inflated compared with smartwatches, and The Verge still encountered occasional nighttime heart-rate gaps.

Buy it if sleep, recovery, stress and women’s-health insights matter more to you than detailed workout metrics.

What the reviewers say

WIRED says the fourth-generation ring looks and feels more like jewelry, while its Smart Sensing platform improves accuracy and wearability. Trusted Reviews also found it noticeably lighter and more comfortable than the Gen 3 Heritage, although it noted that the overall dimensions have not shrunk dramatically.

PCMag calls it the best smart ring it has reviewed for accuracy, features and overall user experience, praising its activity, sleep and stress tracking and its informative app. The Verge agrees that Oura remains on top for now, but warns that the subscription is its biggest weakness and says some smart-ring estimates, particularly steps and calories, should still be treated cautiously.

⚙ Best settings — dial it in

There are no display or performance settings to tune. Correct sizing is the important setup step because the fourth-generation sizing can differ from older Oura rings. For fully calibrated values, see The Verge.

The competition

Samsung Galaxy Ring

Trusted Reviews considers it a strong alternative, while The Verge says its premium design is not dramatically different from Oura’s.

RingConn 2

Trusted Reviews identifies it as another strong competitor that has narrowed Oura’s lead.

Should you buy it?

Yes, if you want a discreet health tracker focused on sleep, recovery, stress and women’s health. Across the supplied reviews, critics agree that the Oura Ring 4 combines comfortable hardware, consistent sensing and the most polished smart-ring app experience. It is harder to justify for workout-focused buyers or anyone opposed to paying a membership after buying expensive hardware.
