Dan got hands-on time with the new Circular Ring 2 smart ring on the CES 2025 tradeshow floor. This subscription-free competitor to the Oura Ring and Samsung Galaxy Ring is one of the first finger-based smart wearables with onboard ECG readings and FDA-cleared AFib detection. With a focus on 24/7 health monitoring and actionable wellness insights, the ring provides detailed sleep reports, daily energy level estimates, helpful workout recovery tips and more. Another big selling point: Unlike Oura and Samsung, Circular Ring 2 users don’t need to purchase a sizing kit for $10 to guarantee a perfect fit. Dan tested the brand’s new Virtual Sizing tool, which requires only your smartphone camera and an Internet connection, to get exact measurements for each of his fingers.
