Why we love it
It is easy to forget you are wearing it. Oura lists Ring 5 at 2.28 mm thick and from 2 grams, and Wired found it far more comfortable than earlier generations over three weeks of day and night wear.
The overnight numbers have outside checks behind them. In an independent 2025 study of 536 nights against ECG, Oura Gen 4, the generation before Ring 5, matched resting heart rate with 0.98 concordance and 1.94% error.
Reviewers rate the software highly. CNET scored Ring 5 9.5 out of 10 with a 2026 Editors' Choice award, and Wired rated it 9 out of 10.

Questions
Is the Oura Ring 5 worth it?
For overnight tracking, yes, if you accept the membership. CNET scored it 9.5 out of 10 and Wired 9 out of 10, and owners rate it 4.4 stars from 2,297 Amazon ratings. Budget about $539 over two years: $399 for the ring plus $69.99 a year.
Does the Oura Ring 5 need a subscription?
In practice, yes. Oura Membership costs $5.99 a month or $69.99 a year in the US, and without it the app shows only basic scores. Wired noted that the subscription still feels mandatory, though new members get the first month free, per Oura.
How long does the Oura Ring 5 battery last?
Oura rates Ring 5 at 6 to 9 days per charge. Testers landed in that range: T3 still had 15% left after almost 9 days, TechCrunch had about 25% left after 5 days, and ZDNET's first charge on a size 6 lasted about 6 days.
Oura Ring 5 vs WHOOP: which should I buy?
Choose Oura for overnight comfort, WHOOP for a screen-free strap built around training. Oura Ring 5 is 2.28 mm thick and costs $399 plus $69.99 a year for full insights, about $539 over two years. WHOOP is sold only as a membership, from $199 a year with the strap included.
Is the Oura Ring 5 FDA cleared?
No. Oura's September 2026 IPO filing says all current Oura features fall under the FDA wellness exemption, so none is FDA cleared. It is a wellness tracker, and its sleep and heart data are for personal insight rather than diagnosis.
