A Deeper Signal, Straight from Your Core
Skin temperature reflects the surface, core body temperature reveals the heat trend within. By combining heat-flux sensing, skin temperature, and physiological modeling, Speediance Strap adds deeper context to how your body responds to training, heat, recovery, and sleep.
