RingConn Gen 3 Smart Ring vs Circular Ring 3

The RingConn Gen 3 is the better pick for most people: longer battery life, a deeper water rating, a wider size range and a charging case that works across RingConn rings. The Circular Ring 3 is the one to choose if you want a single-lead ECG with AFib detection and a thinner profile, and its 4.8-out-of-5 owner rating is strong. Both are subscription-free titanium rings, so the decision comes down to ECG and thinness versus battery, water resistance and sizing.

• Choose the RingConn Gen 3 if you want the longest battery life, a 100 m water rating and a charging case that fits any RingConn ring.
• Choose the Circular Ring 3 if you want a single-lead ECG with AFib detection and the thinnest titanium build of the two.
