## What happened

Oura Ring 5 launched June 2026 at $399 with a 40% thinner design, illness prediction, and nighttime breathing monitoring.

## Our take

The Oura Ring 5 launched in June 2026 at $399, and the most impressive thing about it isn't the thinner design, it's that it caught a reviewer's cold one to two days before he felt sick. The app distills nine data sources into four scores, so you're never staring at a wall of numbers trying to figure out what to do. Existing Oura owners don't have a strong reason to upgrade, but if you've never worn one, this is the version to start with.
