The 5 most exciting Oura Ring 4 features

The long-awaited Oura Ring 4 is finally here, and it’s offering an updated version of my favorite smart ring. The latest from Oura brings a handful of worthwhile upgrades, both in terms of physical design and software improvements. It promises an extra day of battery life over the Oura Ring 3 — extending to eight days — according to Oura. It also offers a sleeker design, new sensors, and updated algorithms for better overall accuracy. Plus, Oura is rolling out a new app to provide a better experience when checking out all that data.
