Our verdict
Where it wins
- Genuinely small and comfortable for 24/7 wear, including sleeping, at 40% smaller and thinner than the previous generation
- 6-9 day battery life beats nearly every wrist-worn sleep tracker or smartwatch
- Independent reviewers have generally rated its sleep stage, HRV, and temperature tracking as accurate and consistent
- Waterproof to 100m so it survives showers, swimming, and sauna without being removed
Where it loses
- Full functionality is locked behind a mandatory $5.99/month (or $69.99/year) Oura Membership; without it you lose the Readiness Score, sleep stage analysis, HRV trends, and most personalized insights
- Only the first month of membership is free with a new Ring 5 purchase, a big cut from the 12 free months that came with the Ring 4
- No display on the ring itself and no way to check sizing on the spot, since you have to order a free sizer, wait, and confirm fit before your actual ring ships
The Oura Ring 5 is a well-built, genuinely small and accurate sleep and recovery tracker for people who don't want a watch on their wrist at night. The catch is that the hardware price is really just the entry fee, since almost every meaningful score and insight sits behind a $5.99/month membership that now comes with just one free month instead of a full year. It's a solid buy if you're prepared to pay the subscription indefinitely, and a poor one if you expected the ring alone to be the whole product.

Common questions
Do I have to pay a monthly subscription to use the Oura Ring 5?
The ring and app will still sync basic data like steps, heart rate, and skin temperature without a membership, but the Readiness Score, sleep stage breakdown, HRV trends, and most personalized insights require an active Oura Membership at $5.99/month or $69.99/year. New Ring 5 buyers get one free month before billing starts.
How do I find my correct ring size before buying?
Oura ships a free sizing kit with plastic sizers for each ring size. You wear the sizer for at least 24 hours, including overnight, before ordering the real ring in your confirmed size.
Is the Oura Ring 5 accurate for sleep tracking?
Independent reviewers have generally found its sleep stage, heart rate, and temperature data to be consistent with other validated wearables. As with all consumer wearables, it estimates sleep stages algorithmically rather than measuring them with clinical-grade equipment.
