Circular’s new smart ring has a built-in ECG

Until today, I could count on one finger the amount of smart rings that offered a one-line ECG in such a small package. Bodimetrics’ Circul+ debuted in 2021, but what it had in heart-monitoring features it lacked in style, or even looking like a real ring. Today at CES 2025, however, Circular is launching its second-generation ring that promises to keep an eye on your heart health.

Circular says the Ring 2 boasts improved sensors as well as the aforementioned ECG, an eight day battery life and a better wireless charging dock. The company added that its companion app and AI has been completely redesigned to offer a “more intuitive and refined user experience.” Not to mention that the body is now cast in titanium with four color finishes; Gold, Silver, Black and Rose Gold.

It won’t be hitting store shelves until February or March 2025, but the company says it’ll cost you $380 when it does.
