1. A step counter system comprising:

  • an accelerometer to detect motion of a user;

    a step calculation logic to utilize the motion detected by the accelerometer to detect and count steps; and

    an incline logic to utilize the motion detected by the accelerometer to make a calculation of an incline of a surface on which the user moved for one or more of the steps, wherein the calculation is performed for a step based on identifying a vertical travel up portion of the step, identifying a vertical travel down portion of the step, and computing a difference between the vertical travel up portion and the vertical travel down portion of the step.
