How Does Apple Watch Calculate Calories Burned

The Apple Watch is a sleek gadget with impressive health and fitness tracking capabilities. One of its standout features is calorie tracking, which can help you better manage your fitness goals. But how does the Apple Watch calculate calories burned so accurately? Let’s break it down.

The Apple Watch uses a combination of biometric data and algorithms to estimate calorie burn. It factors in details like your age, gender, weight, and heart rate, which you input when setting up your watch. Along with motion data from its accelerometer and gyroscope, the watch calculates your active calories—the energy you burn during workouts and physical activity.

The key is the heart rate sensor, which measures your pulse to determine exercise intensity. For high-intensity intervals, the watch calculates more calories, while gentler activities burn fewer. Apple uses advanced algorithms (validated by research studies) to deliver a personalized calorie estimate, which is displayed on the Activity Rings and in the Fitness app.

While the Apple Watch is a powerful fitness tool, it focuses on active and resting calories.
