Oura Ring introduces social sleep features for health tracking.

Oura, the company behind the smart ring that tracks biometric data, has launched a new community-sharing feature called Circles, which allows users to share readiness, sleep, and activity scores with private groups. The feature is aimed at creating a small, intimate group of empathy and support, rather than competition. Oura has also rolled out a new sleep staging algorithm that provides a variety of scores and areas for improvement. The company has looked to get its rings onto more hands through added features and partnerships, including a deal with Best Buy to be its first U.S.-based large-scale retail partnership.
