Product 1: Polar Grit X2 Pro
4.0

The watch offers non-medical ECG checks that reviewers found useful for intentional HRV-style spot checks rather than medical screening.

Product 2: Samsung Galaxy Watch 7
4.2

ECG support is a clear strength, but reviewers repeatedly note that access is limited by Samsung-phone requirements and regional availability.

fit
Product 1: Polar Grit X2 Pro
3.1
