TreadCal helps you understand your incline-treadmill and walking-pad workouts. Enter your treadmill’s speed and incline—or measure its stopped deck with your iPhone—then start your workout on Apple Watch. TreadCal combines your weight, grade, speed, optional weighted vest, and rail use to estimate active calories. MAKE EVERY CLIMB COUNT • Incline-aware active-calorie estimates • Vertical climb and approximate treadmill distance • Live heart rate and heart-rate zones on Apple Watch • Time spent in each heart-rate zone • Weighted-vest calorie contribution included in your total • Workout receipts with steps, duration, and workout settings • A shareable climb card for every workout; the artwork grows with the climb MEASURE YOUR TREADMILL Use two-position iPhone calibration to map your treadmill’s console setting to measured percent grade. Calibrate only while the belt is stopped. YOUR WORKOUT IS YOURS Apple Watch workouts require permission to write Workouts and Active Energy to Apple Health. Other Health read permissions and Motion permission are optional. TreadCal keeps your profile, calibration, and workout history on your devices. No account, ads, or analytics. TRY THREE WORKOUTS Your first three completed workouts are included. Unlock unlimited workouts with a single TreadCal Pro purchase. No subscription. TreadCal is an exercise estimator, not a medical device. Calories and heart-rate zones are estimates; distance depends on the speed you enter. Never place your iPhone on a moving treadmill belt. Heart-rate zone features require watchOS 27 and appropriate permissions.
