Oura introduces new Oura Ring 4 with slimmer sensors and enhanced accuracy

Oura has unveiled its latest smart wearable, the Oura Ring 4, made from all-titanium and featuring improved sensors and enhanced accuracy.

The ring presents "Smart Sensing" technology, which adapts to the wearer’s finger for more precise tracking, including a 30% improvement in blood oxygen sensing and better heart rate monitoring. With recessed sensors and a slimmer profile, the ring is now more comfortable and offers twelve sizes, catering to a broader range of users.

Battery life has been extended up to eight days, and a redesigned app simplifies health monitoring with new features like automatic activity detection and fertility tracking.

The Oura Ring 4 comes in six colors and ships starting October 15, priced at $349, with a subscription service remaining a part of the offering. The launch follows rumors of potential competition from Apple and Samsung in the wearable ring market.
