Galaxy Watch 5's Temperature Sensor Enables Skin Temperature-Based Cycle Tracking in 32 Countries

Samsung has added skin temperature measurement to its existing calendar-based Cycle Tracking feature on Galaxy Watch5 and Galaxy Watch5 Pro, enabling users to track menstrual cycles and overall health. The new feature will be progressively released via Samsung Health app updates in Korea, the US, and 30 European markets. The Cycle Tracking feature is powered by Natural Cycles and enables users to track skin temperature changes, a good estimate of basal body temperature, during sleep right from their wrist.
