Oura on Thursday unveiled the fifth generation of its popular smart ring, starting at $399. The Ring 5, which Oura describes as the world’s smallest smart ring, arrives just a year and a half after the company launched the Ring 4 and seven months after the Ring 4 Ceramic. The Ring 5 is 40% smaller than its predecessor and comes with more accurate sensing and enhanced battery life.
The Ring 5 is launching alongside new software updates that include blood pressure signals, live activity tracking, on-demand care, and other features that will also roll out to the Oura Ring Gen3 and later.
