LocusSigma is a very simple plugin for Locus Map which provides a shortcut for quickly exporting tracks into the SIGMA RIDE app. Without the plugin, transferring tracks requires you to export them to a GPX file and importing it in SIGMA RIDE via its import menu or a file browser, both of which is cumbersome as you have to locate the file, particularly if you are out on a ride and need to plan a new route.

Usage:

• Install Locus Map, SIGMA RIDE and the LocusSigma app.
• In Locus Map, select a track (from the map or Tracks & Routes manager) and tap the 'share' button
• Select SIGMA RIDE.
• The track will be automatically imported into SIGMA RIDE and can be directly sent to a connected device.

LocusSigma itself has no settings or other user interface. You can't start it directly from the Android launcher/home screen.
