A GPX file or “GPS Exchange” is a file format that allows you to store your route on your computer or smartphone. In other words, it allows you to exchange GPS coordinates by sharing them in the form of a file, which can be imported into a GPS application. To read this format, you’ll need to download an application that allows it to be opened.
Once you’ve downloaded the application, you simply import your GPX file stored on your device.Your phone will then display your position and allow you to track your progress in relation to the route in real time.
