Ouraâ s new Ring 5 is a massive upgrade for smart rings, dramatically shrinking in size and weight to bring them right into line with standard wedding bands and other jewellery.

Oura's New Ring 5 Is Smaller and Lighter--and Adds an AI Health Coach But the real upgrade is Oura's push into AI-powered health insights and proactive monitoring. Two years on since the Oura Ring 4, Finnish health tech company Oura is back with a new smart ring --right in time to compete with the other screenless fitness tracker of the moment, the Fitbit Air . The Oura Ring 5 doubles down on the company's minimalist ethos with a smaller ring design, upgraded durability, and--unsurprisingly--a suite of AI-powered wellness features . The Ring 5 is available for preorder today and begins shipping June 4. It starts at $399 in silver and black, while premium finishes--Stealth, Brushed Silver, an updated Gold, and a new Deep Rose color--cost $499.
