The second generation smart ring focuses on heart health monitoring and upgrades many features to keep up with industry competition. According to the press release, there is an FDA-approved Atrial Fibrillation detection algorithm for arrhythmia monitoring included in the ECG capability for “real-time cardiovascular health insights “, and improved sensors are said to help increase the accuracy of the data collected.

Most smart ring brands send customers a ring size kit to try on the exact ring size before deciding to buy a smart ring. Circular is changing this process with Digital Ring Sizing that users can try on their phone — no physical set required. Digital ring sizing uses the smartphone’s camera to determine the user’s ring size. To our knowledge, this is the first smart ring brand to use a smartphone camera for ring sizing.
