    Why do different apps running simultaneously give varying GPS distances?

    I use Jabra Sport, and Fitbit when I run. They rarely, if ever produce the same distance even though I start them at the same time. Example, on a recent run, Jabra measured it at 4.04 miles, Fitbit at 3.89. How do I get these in sync?
