Using heart rate from your Apple Watch, HeatReady estimates your physiological strain during heat training and guides you through a structured acclimatization plan. KEY FEATURES Heat strain monitoring Live monitoring of your physiological strain during heat training sessions, with an estimated core temperature derived from heart rate using a Kalman-filter model. 14-day acclimatization protocol A structured day-by-day heat acclimatization plan tailored to your profile, so you know exactly what to do each day. Acclimatization status Track how acclimatized you are with clear, evidence-based indicators, and see when your adaptation begins to fade.
