Heat Ready

HeatReady helps athletes prepare for training and competition in hot environments by tracking heat acclimatization with science-based methods. 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. Decay tracking Heat adaptation fades when you stop training in the heat. HeatReady estimates this decay so you can time your final preparation before competition. Session history Review every heat session with detailed trends and metrics. Apple Watch companion Start and monitor heat sessions directly from your wrist. DESIGNED FOR ATHLETES Whether you compete in track and field, endurance running, cycling, or team sports, HeatReady helps you arrive at the start line prepared for the heat.
