At CES 2025, Circular has revealed its new Circular Ring 2, a significant pivot from its final Circular Ring Slim in design, measurement, and options. It focuses extra on well being as an alternative of wellness alone, with an FDA-approved electrocardiogram (ECG) for lively AFib detection.
But to squeeze within the ECG, Circular needed to make the Ring 2 heavier and reduce its signature haptic motor, which might buzz your finger for notifications, alarms, reminders, or leisure steering.
We spoke with Circular CEO Amaury Kosman simply previous to CES 2025 in regards to the new Circular Ring 2. He mentioned that they “did not do all the things as completely as we wished to” when designing the Circular Slim, its first ring with absolutely customized tech designed solely in France. The Ring 2 was designed to repair its predecessor’s connectivity and sync points, and with a newfound concentrate on aesthetics, accuracy, and longevity.
First, they needed to “redo the whole mechanics of the ring” to offer it rounded corners as a result of previous customers “did not like the texture” of the flat-edged variations. They additionally switched from aluminum to titanium and to a brand new hypoallergenic resin on the within. And they provide 4 colours now, with Gold and Rose Gold obtainable.
The Circular Ring 2 weighs about 5g, effectively above the 2g Slim, however the bigger measurement lets them match a bigger battery and the brand new AFib-detecting ECG. While previous fashions solely lasted 2 days in “efficiency mode” or 4 days in “eco mode,” Kosman says the Ring 2 will final 8 or 4 days, relying on how usually you need the ring to pattern.
Kosman says that its new ECG will likely be able to a number of kinds of arrythmia detection, beginning with AFib, tachycardia, and brachycardia, and with different unannounced options coming by way of OTA replace all through 2025, all primarily based on the ECG. At launch, the Ring 2 will solely supply lively AFib detection by holding your finger for 30 seconds on the ring; Kosman says they wish to use the PPG to “passively” catch irregular coronary heart rhythm in a single day and immediate customers to take an ECG, however that it is not prepared but.
For context, Ultrahuman introduced an AFib powerplug replace final yr, nevertheless it makes use of PPG knowledge, requires a subscription, and is not obtainable within the U.S. but. Otherwise, a lot of the greatest sensible rings don’t have any ECGs or AFib detection, making Circular forward of the sport for coronary heart well being knowledge. Kosman additionally hinted that they could attempt to add different well being metrics like blood stress, however had nothing definitive to say.
Unfortunately, Circular could not match each an ECG and a haptic motor into the Ring 2, a minimum of not with out introducing “waterproofing and battery points” in preliminary prototypes. But Kosman says a “new model” of the Ring 2 will carry again haptics; he merely cannot say when it will arrive but.
Some different new Circular Ring 2 elements embrace a brand new wi-fi charging dock, a “next-gen makeover” for the Kira AI that interprets your wellness knowledge, and ovulation monitoring.
Most apparently, you’ll use your telephone digicam for digital finger sizing: You’ll use one thing like a bank card for a reference level and have the Circular app let you know your 5 ring sizes on that hand. This will remedy the inconvenience of getting to attend for a bodily sizing package earlier than shopping for one — although we’ll need to see how correct the digital software is for locating a snug match.
The Circular Ring 2 can have a crowdfunding marketing campaign in January earlier than releasing someday in February or March 2025, with a beginning worth of $349.
