Circular has officially opened pre-orders for the Circular Ring 2, bringing new health-tracking features and quality-of-life upgrades. After turning heads at CES 2025, where it collected 10 industry awards and over 200 media mentions, the Circular Ring 2 is now available through an early pre-order campaign offering savings of up to $310.
The latest model includes FDA-cleared AFib detection, a wireless charging case, and a digital sizing system that eliminates guesswork when choosing a ring size. Early backers can secure the $549 ring for as low as $239 via the Kickstarter campaign, with shipments expected in June 2025.
What’s New with the Circular Ring 2?
Digital Ring Sizing – No More Guesswork
Finding the right ring size has never been the easiest process, but Circular has solved that. The new Digital Ring Sizing technology lets users measure their ring size directly from a smartphone before ordering, eliminating the back-and-forth of trial sizing.
Wireless Charging Case – Power Without the Cords
Charging a smart ring should be simple, and now it is. The optional wireless charging case lets users store and recharge their ring anywhere, keeping it powered for uninterrupted health tracking. No tiny charging cables to misplace—just drop it in the case and go.
Women’s Health Suite – Smarter Cycle and Wellness Tracking
The Circular Ring 2 now includes a Women’s Health Suite, adding cycle tracking, temperature monitoring, fertility insights, and menopause support. These features provide personalized biometric insights, helping users track patterns and gain a better understanding of their health.
Advanced Health Monitoring – FDA-Cleared AFib Detection
The Circular Ring 2 isn’t just tracking daily activity—it’s providing real-time ECG monitoring with FDA-cleared AFib detection. With detailed sleep-stage analysis, heart rate tracking, and Kira AI-driven insights, users have a clearer picture of their overall health.
Many of the best features from the previous model are still here, including blood oxygen monitoring, heart rate tracking, activity tracking, and sleep analysis.
