On June 4, 2026, Oura began shipping the Oura Ring 5 — announced May 28, 2026 — positioning it as both the world's smallest smart ring and its most clinically ambitious. The device is 40% smaller than its predecessor, built from lightweight, non-allergenic titanium, priced starting at $399 for base finishes, and backed by a hardware architecture the company says delivers greater sensing accuracy across more finger types and skin tones than any previous generation.
But the hardware story is almost secondary to what the software is doing. Oura Ring 5 launches with a suite of health features that move the device from the wellness tracking category into a space that clinicians, researchers, and technology analysts are paying close attention to: continuous, passive biosensing as a tool for preventive and predictive health monitoring.
