The new Smart Ring from Circular has an integrated ECG

To date, I could count on one finger how many smart rings offer a single-line ECG in such a small package. Bodimetrics’ Circus+ debuted in 2021, but what it had in heart monitoring features, it lacked style or even looked like a real ring. Today at CES 2025However, Circular presents its second-generation ring that promises to keep your heart’s health in mind.

We had a chance to take a look at the rings at CES Unveiled today, and they actually shine. They also feel remarkably light. The sensor nodes inside the rings are noticeable when you first put the ring on, but after about a minute of wearing it, it hardly feels like you’re wearing a ring at all.

According to Circular, the Ring 2 has improved sensors as well as the aforementioned ECG, eight days of battery life and a better wireless charging base. The company added that its companion app and AI have been completely redesigned to provide a “more intuitive and refined user experience.” Not to mention, the case is now made of titanium with four color finishes; Gold, silver, black and rose gold.

This latest generation doesn’t have the vibrations of Circular’s first-generation rings, but the company’s co-founder told us that the vibrations will return in an upcoming iteration. For now, the second-generation Rings should go on sale in February or March 2025, but the company says they will cost $380 then.
