The accelerometer and algorithms that the device uses to count your walking steps are highly sensitive, even small differences may affect the accelerometer and algorithms. You must provide accurate personal data during the device’s initial configuration. For example, if you enter wrong gender, height, weight, or age, it could result in inaccurate exercise data, such as incorrect counting of steps, distance, or calorie.
In addition, factors such as your arm swing, stride, posture, road surface, and slope can also affect the step count.
