The Circular Ring 2 is a cutting-edge smart ring announced just in time for CES 2025, offering unique features that set it apart in the competitive wearable tech market. Chief among these innovations are its on-finger ECG readings with FDA-cleared atrial fibrillation (AFib) detection and an eco-friendly digital sizing process.
These advancements make the Circular Ring 2 a standout contender against established rivals like the Oura Ring and Samsung Galaxy Ring. The ring is expected to be available this spring in four finishes, starting at $380, and it boasts subscription-free usage, a notable advantage over some competitors.
In terms of design, the Circular Ring 2 has undergone a complete overhaul compared to its predecessor, the Circular Ring Slim. The new model features a durable all-titanium exterior, addressing previous complaints about the Slim’s susceptibility to scratches.
Its environmental sealing has also been upgraded from IPX8 to IP68, making it better suited for everyday wear, though not for swimming. The inclusion of advanced sensors enhances tracking accuracy, while the introduction of ECG readings and AFib detection positions the Circular Ring 2 as a frontrunner in health-monitoring smart rings.
Battery life is another area where the Circular Ring 2 has made significant strides, offering up to eight days of usage per charge—a dramatic improvement from the Slim’s two-day battery life. This aligns the Ring 2 with competitors like the Oura Ring 4 and Samsung Galaxy Ring. The device also comes with a new wireless charging dock, adding convenience to the user experience. These improvements, coupled with 24/7 health and sleep monitoring, enhance its appeal as a robust wearable.
A major innovation in the Circular Ring 2 is its digital sizing process, which eliminates the need for traditional sizing kits. This feature, integrated into the companion app, uses a smartphone camera to measure the user’s exact ring size, providing a more sustainable and user-friendly alternative to disposable sizing kits. The redesigned app further streamlines navigation, addressing usability concerns reported with the Slim model.
The Circular Ring 2 appears to address the shortcomings of its predecessor while introducing industry-first features that could make it a serious contender in the smart ring market. If the device delivers on its promises of improved battery life, durability, usability, and reliability, it could challenge market leaders like the Oura Ring 4 and Samsung Galaxy Ring.
With its subscription-free model and health-focused innovations, the Circular Ring 2 might just set a new standard for smart rings in 2025. Hands-on impressions at CES 2025 are eagerly anticipated to validate these claims.
