Oura Ring 5 Smart Ring Health Tracker

Overview

The Oura Ring 5 in silver, size 8, a titanium smart ring that tracks sleep, activity, stress and other health metrics through the Oura app. This is the ring itself, not the sizing kit.

Oura Ring 5 uses its own sizing standard that differs from regular jewelry and from earlier Oura generations, so Oura recommends ordering its sizing kit first rather than guessing from a normal ring size. Full use of the health metrics also requires an Oura membership, which starts free for one month for new members and then runs 5.99 a month, so the ongoing subscription cost matters as much as the ring price itself.

• 6 to 9 days battery life
• 50-plus tracked health metrics
• All-titanium, scratch-resistant design
• Compatible with Android and iOS

Who it's for

Fits someone already comfortable with subscription health trackers who wants sleep and activity data without a wrist-worn device. Less suited to buyers who won't pay the ongoing membership fee, since deeper metrics sit behind that subscription.

Pros and cons

Performance notes

Oura Ring 5 is described as 40 percent smaller than the prior generation, with larger, more capable sensors intended to offset that size drop with more accurate readings. Battery is rated 6 to 9 days per charge, and the ring tracks over 50 metrics spanning sleep, activity, stress, heart health, metabolic health and women's health, syncing to the Oura app and to more than 40 third-party apps.
