This is a look back at an event from . We wrote it on November 11, 2026, from the sources listed at the end.
What to know
- The Oura Ring 5 began shipping on June 4, 2026, at $399, or $499 for premium finishes.
- Oura described it as the slimmest smart ring, at 2.28mm thick.
- New software features included real-time workout tracking, Menopause Insights and lab result uploads.
Smart rings compete on a simple test: whether you forget you are wearing one. Oura's fifth-generation ring, which began shipping on June 4, 2026, was built around that.
The hardware
Wareable reported these figures from the launch:
| Oura Ring 5 | |
|---|---|
| Price | $399, or $499 for premium finishes |
| Width | 6.09mm |
| Thickness | 2.28mm |
| Weight | 2 to 2.69 grams, depending on size |
| Battery | About a week |
Oura said the internal components take up 40% less space than in the Ring 4, and described the sensor design as having 12 signal pathways. More pathways give the ring more chances to get a clean reading when it rotates on the finger, which is the main source of error for any ring.
The software
- Real-time workout tracking. Earlier rings summarized a workout afterward.
- Menopause Insights. Tracking designed around the symptoms of perimenopause and menopause.
- Lab Uploads. A way to bring blood test results into the app next to the ring's data.
Why it mattered
The lab feature points to where the category was heading in 2026. A ring measures a few signals continuously. A blood test measures many things once. Putting them in one place is a step toward the ring being part of a health record. That is a different thing from a sleep tracker.
Other companies made similar moves in the same weeks. Whoop announced clinician consultations and Google launched an AI health coach, which we cover in a $99 Fitbit with an AI coach, and Whoop adds doctors.
What to keep in mind
A thinner ring does not change what a ring can measure. It still estimates sleep stages from movement and heart data, and its scores still come from the company's own formula. See what a sleep score measures for which numbers to trust. Oura's features also sit behind a monthly membership, so the price of the ring is not the whole cost.
