Every Circular code here comes from Circular itself or its official affiliate program, never copied from another coupon site. When you shop through our links, Circular may pay us a commission. It never changes your price. We give 50% of that commission to the charity, club or school you choose, at no extra cost to you.
Circular makes the Circular Ring 2, a titanium smart ring weighing about four grams that pairs with an iPhone or Android app. It tracks sleep, activity and heart data, can take a single-lead ECG reading, and comes with what Circular calls 14-plus app tools, from a smart alarm and guided breathing to medication reminders. The battery lasts up to eight days, it charges wirelessly in about an hour, and it's water-resistant to 50 m. Circular says the ring is not a medical device.
The company has been designing in Paris since 2018. Its sales are handled by Circular Health Limited, registered in Paris, and it says it's funded by its founders and a group of business angels and family offices. The Circular Ring 3 series, Ring 3 Pro and Ring 3 Slim, is announced with pre-orders opening in December 2026.
In the US the Ring 2 costs $349 as a one-off purchase, with no compulsory subscription, though some premium features are paid. It's sold in nine sizes, US 6 to 14, and runs about half a size large. It's eligible for payment with HSA or FSA funds.

|---|---|
| Returns | 14-day returns: you pay return shipping, and a non-refundable $25 for shipping and handling is deducted from ring refunds. Size exchanges within 14 days on an unworn ring. One-year manufacturer's warranty (two years in the EU). |
