New Smart Ring Series Introduced
Circular has announced its new Ring 3 Series, which includes two models: the Ring 3 Pro and the Ring 3 Slim. This series follows the Ring 2, which debuted at CES 2025. The new rings aim to combine health tracking with additional functionalities like mobile payments and alerts.
Key Features Across Both Models
Both the Ring 3 Pro and Ring 3 Slim incorporate an integrated NFC chip, enabling contactless payments. These payments are compatible with Visa and MasterCard products. Additionally, both versions feature vibrating alerts, which can be used for silent wake-up alarms, medication reminders, and guided breathing exercises.
Ring 3 Pro Specifications
The Ring 3 Pro model includes FDA-cleared ECG for atrial fibrillation (AFib) detection, blood pressure trend tracking, glucose tracking, advanced sleep analysis, and comprehensive biometric monitoring. It features a slimmer design than its predecessor and uses titanium for improved durability. The battery life has been extended from seven to up to 12 days. Finishes include gold, rose gold, silver, and black.
Ring 3 Slim Details
The Ring 3 Slim is designed to be thinner and lighter than the Pro model. It offers basic health and wellness tracking, including sleep, heart rate, HRV, SpO₂, skin temperature, and daily activity. The Slim model provides up to 10 days of battery life and does not include AFib detection.
Market Context
The launch of the Circular Ring 3 series occurs during a period of increased competition in the smart ring market. This follows recent releases such as the Oura Ring 5 and RingConn Gen 3. Circular CEO Amaury Kosman stated that the company recognizes not all users require every health feature, with some preferring a well-designed ring for core functions.
