Circular Ring 2

The Circular Ring 2 is a titanium smart ring from the French company Circular. It tracks sleep, heart rate, blood oxygen and activity and adds a single-lead ECG taken by touching the ring with a finger of the other hand, with signs of atrial fibrillation flagged. It comes with a charging dock, works without a required subscription and offers optional paid features. The company states it is not a diagnostic device.
