Downloads

The links below are ZIP files that contain the applications for MacOS and Windows, and an executable jar file for Linux.

When you start GPS Speedreader the first time, you will probably see a warning dialog “GPS Speedreader can’t be opened because it is from an unidentified developer”. To open the application anyway, you can right-click on the GPS Speedreader icon, which will show a slightly different dialog that gives you an option to open the application.

Windows
