The Ring 2 introduces a Digital Ring Sizing feature that utilizes a smartphone camera for accurate sizing, streamlining the purchasing process.

At CES 2025, Circular unveiled its second-generation smart ring, the Ring 2, which enhances heart health monitoring capabilities.

Constructed from durable titanium, the Ring 2 features an increased environmental sealing rating of IP68, making it suitable for hand washing and showering.

This new smart ring boasts an impressive battery life of up to eight days on a single charge, matching the Oura Ring 4, although real-world usage may vary.

Circular's CEO, Amaury Kosman, acknowledged issues with the previous model and emphasized improvements in accuracy and quality for the new version.

The smart ring market is rapidly evolving, with significant competition from brands like Oura and Ultrahuman, as evidenced by an 88.4% increase in shipments in 2024.
