Circular Ring 3 vs Aurora Motion 2.0 Blood Pressure Ring

The Circular Ring 3 is the better-built ring: titanium inside and out, thinner at about 2.23 mm, 50-metre water resistance and up to 12 days of battery. The Aurora Motion 2.0 is the broader health tracker, adding automatic blood pressure trends, VO2 Max, family data sharing and on-demand ECG in the app, and it has far more owner ratings behind it. Buy the Circular if fit, finish and durability matter most; buy the Aurora if blood pressure trends and a wider metric set are what you want.

• Choose the Circular Ring 3 if you want the slimmer titanium ring with longer battery life and no subscription.
• Choose the Aurora Motion 2.0 if automatic blood pressure trends and a wider set of health metrics matter more than a thin titanium build.
