stress tracking
Product 1: Polar Grit X
4.0

Stress tracking evidence comes from the guided Serene breathing feature and recovery/stress context rather than a broad stress dashboard.

4.2

Value was frequently praised because the watch delivered deep training and outdoor features for less than several major rivals.
