GPS Visualizer for Android (com.mendhak.gpsvisualizer) on Google Play
This app allows you to import GPX and NMEA files generated from other sources. You can then* Display tracks on a map * Import from Google Drive or import a local file* Show various graphs about the track * Elevation over time, elevation over distance, speed over distance, speed over time, distance over time. * Show various stats about the track * Elevation, speed, time and distance stats* Waypoints will appear on graphs if they have enough metadata (elevation)I created this as I wanted a 'portable' version of the app to view my progress after a day of trekking. Serves as a companion app to GPSLogger for Android.Inspired by the excellent UTrack and GPSVisualizer.com online tools. Does not actually require write access, it is forced by Google Maps.
