Overview
- The company unveiled the Ring 3 Pro and Ring 3 Slim Thursday at IFA in Berlin, confirming both models will support NFC contactless payments and on-finger haptic alerts.
- The Ring 3 Pro adds an FDA-cleared ECG for atrial fibrillation detection plus sensors for blood-pressure trends and glucose trends, while the Ring 3 Slim drops the ECG to achieve a thinner, lighter form and retains core metrics like heart rate, SpO₂, sleep, HRV and skin temperature.
- Both rings will deliver silent wake-up alarms, medication reminders and health alerts through vibration and will accept Visa and Mastercard for tap-to-pay transactions stored on the ring.
- Circular said basic ring functions will remain subscription-free but that users must opt into a paid subscription to enable the new blood-pressure and glucose features, and the company has not yet announced pricing or exact release dates beyond an early‑2027 target.
- The launch intensifies competition with devices such as the Oura Ring 5 and recent BP moves from Apple and Huawei, while reviewers note Circular must address past app syncing problems and prove the real-world accuracy of photonics-based blood-pressure and glucose trends before the rings’ health claims can be fully trusted.
