Why does your app show a different calories record from the other app I have?

Edited

Our app tracks only the calories burned through walking, so you can see how much energy you’re using from this specific activity. Your other app may show your total daily calorie burn from midnight to the current time, including your baseline metabolic rate and your activity level (e.g., sedentary, lightly active, moderately active, very active). This means the other app’s total may include calories burned during sleep or from other activities. While both methods are valid, our app focuses specifically on calories burned by walking, rather than your overall daily expenditure.
