Your tracker calculates distance based on an average stride length for your height (you specified your height when you first set-up your tacker). Your distance figure may vary if you have longer or shorter legs than the average for your height. Although there isn't currently an option to set a stride length in the app, increasing/decreasing your height will allow you to compensate for this.
If your tracker supports GPS, you can track your activities with an even greater level of accuracy by starting a sports mode that support GPS (Walking, Running, Hiking or Cycling).
The following article explains how to start a sports mode with GPS: How do I capture a map of my route using GPS?
