Oura’s newest smart ring is tiny on the finger but big on impact

• Oura has officially announced the Oura Ring 5.
• The new ring is 40% smaller than the previous generation and adds blood pressure trend monitoring, live activity tracking, and other expanded health features.
• The Oura Ring 5 starts at $399 and begins shipping on June 4.

Smart rings are already tiny tracking powerhouses, but Oura still found room to shrink things further. Today, the company announced the Oura Ring 5, a dramatically slimmer new generation that also expands Oura’s focus on proactive health tracking.

The Ring 5 is 40% smaller than the previous model, which is a pretty wild reduction for a category that already packs a ton of tech into very small packaging. To accommodate the change, the smart ring features updated sensing architecture with more powerful LEDs and improved signal quality that should actually boost accuracy across more skin tones.
