OziTrackConverter is a free Android app by Igor V.Borisov that allows you to convert tracks into routes for OziExplorer (*.rte) or MapSource (*.gpx). The app can also convert *.plt files to *.kml, *.kmz, and *.gpx formats, as well as to OziExplorer route (*.rte) and route (*.gpx).

One thing to note is that from Androidand later, Google does not permit third-party applications to write to external SD-cards, only to read. Therefore, it is recommended to move the source file to internal memory before using the app.

Overall, OziTrackConverter is a handy tool for those who need to convert tracks to routes or change file formats on the go.
