GpsMaster is a free (GNU GPL v2) and open source desktop application used to create, view, edit and analyse GPX files. The program is focused toward the analysis of recorded tracks, but also offers features for planning outdoor activities such as backpacking, hiking, and biking.

Written in Java, it runs on Linux, Windows, MacOS or any other platform supporting Java 1.8 to 1.12.

GpsMaster is based on GPXCreator by Matt Hoover. Without his work, GpsMaster wouldn't exist today.
