Oura Ring 5 review: a stunning generational leap for smart rings
Oura has released its Ring 5 health-tracking wearable, offering a slimmer and lighter design comparable to a standard wedding band. The device starts at $399 and requires a $5.99 monthly subscription to unlock most of its health data features.
Why this matters: A ring that tracks your sleep, heart rate, and body metrics around the clock is collecting a dense, continuous record of your physical life. That data sits behind a subscription wall, which means Oura controls access to information your own body generated. If you stop paying, you lose it. The more capable these devices get, the more it matters who owns that health data, what they can do with it, and whether you can ever fully take it back.
