Circular sells the Circular Ring 2, a smart ring designed in Paris that tracks sleep, activity and heart data through the Circular app.
No subscription is needed to use its features, and shipping and handling are already built into the ring's price, so any discount comes straight off the ring itself.
Circular was started in Paris by founders who wanted to follow their own health day to day and found that existing wearables mostly counted steps and scored workouts. The company is funded by its founders together with business angels and family offices, and its staff of engineers, product specialists and designers works with input from clinical advisors. Circular says everyone on its engineering team wears the ring.
The Circular Ring 2 is a titanium band of about four grams with seven sensors, and the app adds Kira, an AI health coach that explains readings in plain sentences. Features listed on the site include a 40-second single-lead ECG, blood pressure trends calibrated against a cuff, sleep stages and a medication reminder. A Circular Ring 3 is in development, with a waitlist open.

More about shopping at Circular
Worldwide
The ring ships globally, reaching Europe in about 5 days and Asia in about 3.
What a return costs
You pay the return postage, Circular keeps a fixed $25 shipping and handling fee, and import taxes stay unrefunded.
Size exchanges
A sizing swap runs separately from a return, inside 14 days of delivery on an unworn, intact ring.
Warranty
The manufacturer's warranty on the ring runs one year, stretching to two years for buyers in the EU.
HSA/FSA
In the US the smart ring is generally eligible for HSA or FSA spending.
Pick your ring size before you apply anything, because a size exchange and a return follow different rules and a return costs you the $25 fee.
Circular doesn't describe where its code box sits, so look for it on the way to payment.
Since shipping is already in the price, there's no shipping code to hunt for.
If you plan to pay with HSA or FSA funds, check the total after the discount, as that's the amount your account covers.
Klarna is listed among the payment options if you'd rather spread the coSt.
More ways to save at Circular
Circular Coins are earned in the app for daily sleep and energy scores, with streak multipliers, and can be spent on rewards and deeper analysis screens.
They're a wellness reward, not money off the ring.
The bigger saving for US buyers may be HSA or FSA eligibility, and the lack of a required subscription means nothing more to pay after the ring arrives.
