This application enables path tracking. It also enables ghost mode competition: you can re-open stored track and run/walk against yourself. Tracks are stored in KML format and can be opened on computer.

You can also upload other user's files on your device and compete with their ghost runners. Use files with TRK extension.

Please see support page link or go to http://marjandeveloperelectro.blogspot.com/2011/06/gps-trainer-support-page.html for more information. Basic principle of usage is: go to settings, choose track file, then touch either 'ghost mode' or 'display track' option. You normally start tracking with flipping of a switch, and when you flip switch back, track will be saved. When you compete, tracking is turned on automatically.

Please don't use this utility in any manner that would or could hurt you or anyone else!

Warning: Continued use of GPS running in the background can dramatically decrease battery life.
