The Oura Ring 5

The Oura Ring 5 is Oura's thinnest, lightest smart ring yet — 40% smaller than the Ring 4, with redesigned sensors, up to 9 days of battery life, and new proactive health features like Health Radar and Blood Pressure Signals.

Introducing the Oura Ring 5 — the world's smallest smart ring, and Oura's most advanced yet. Every internal component has been re-engineered and shrunk by 40% compared to the Ring 4, without sacrificing the week-long battery life the brand is known for.
