Circular Unveils Ring 2 at CES 2025 with ECG and AFib Detection

At CES 2025, Circular has redefined wearable technology with the unveiling of the Circular Ring 2, a new and improved smart ring that combines state-of-the-art health monitoring and sophisticated design.

The new Circular Ring is more than just a stylish accessory. Featuring real-time ECG functionality, it allows users to gain critical insights into their heart health. Its FDA-cleared algorithm for atrial fibrillation (AFib) detection capabilities bring peace of mind by notifying wearers of potential heart irregularities.

Crafted with premium-grade titanium, the Circular Ring 2 comes in four refined finishes—Gold, Silver, Black, and Rose Gold—catering to diverse style preferences. Its modern redesign not only enhances aesthetics but also ensures resilience in daily wear.

For the first time in the smart ring industry, Circular has introduced digital ring sizing, a unique feature that eliminates sizing challenges by using smartphone technology to determine the perfect fit before purchase. This innovation simplifies the buying process and ensures a comfortable, accurate fit for all users.

Below are some of the highlights of the new Circular Ring 2:

• Improved Sensors: Achieving greater precision in monitoring metrics such as heart rate, sleep stages, and activity.
• Extended Battery Life: Operating continuously for up to eight days on a single charge, perfect for long-term health monitoring.
• Wireless Charging Dock: Streamlining the recharging process with a user-friendly docking station.
• Revamped App: The companion app has been redesigned with intuitive navigation and a luxurious aesthetic, ensuring a seamless user experience that complements the ring’s elegance.

“The Circular Ring 2 isn’t just a wearable; it’s an empowering statement of wellness and style. By integrating advanced technology with refined design, we’re giving users the tools to take charge of their health without sacrificing sophistication,” said Circular CEO and Co-Founder Amaury Kosman.

The Circular Ring 2 will retail at $380 and is expected to launch in February or March 2025 following a crowdfunding campaign kicking off this January.
