Trackalizer is intended to analise recorded GPS tracks. It calculates statistics, builds various profile graphs and shows track on a map. Also you can inspect any track point on graph or on map.

Available graphs and profiles:
• Elevation over distance
• Elevation over time
• Speed over distance
• Speed over time
• Distance over time

Elevation and speed data is smoothed to show nice graph and provide more accurate statistics.

If your track does not contain elevation or it is inaccurate you can download DEM data from MapQuest. It's useful when you have a route track and want to estimate climb and descent.

File formats supported:
• GPX - GPS eXchange Format
• PLT - OziExplorer Track Point
• KML - Keyhole Markup Language

On Android 4.0 and above you can share your track files to Dropbox, Google Drive, Email, etc. Rename and delete files.

App is in BETA state. Please send me your tracks if you have problems with them.
It was tested on android 4.x devices. Nevertheless it can work on 2.x devices as well but with minor UI differences.

    Very easy to look into details of downloaded or own recorded track in gpx format. Minor stability issues - can't gracefully handle malformed gpx files - but still a definite keeper.

    Very good. The only remarks: if the slider for point by point following of track would be at the bottom of the screen, it'd be more natural to use. Also, it's difficult to make the slider stop exactly at a desired point, like the one of max speed, for instance. It'd be nice if one could tap to move the slider point by point, for fine tuning. It'd also be good to be able to see and follow data w
