Great app
And also great website! I propose to add some things: 1. GPX downloading, sharing via mail and uploading in cloud (i.e. OneDrive). Last will be very useful for Windows Phone smartphone users because of GPX Viewer app that can view the tracks from OneDrive. 2. Merging selected tracks with subsequent functionality described in point 1. It will be very useful for planning trips. P.S. WP smartphones have greatest app HERE maps in my opinion. If your track database will be integrated in this app i certainly pay any price for that functionality.
