I tried he app to use it as a converter tool. What I need is gpx files to import them in MotionX. So I drawed some tracks and saved them as kml / kmz files. Then import the kml in "kml & gpx pro", which seems to work (kml file is listed in "list"). BUT: as soon as I try to open the imported kml file on the map by double clicking it ("list") - nothing happens. Tried another kml - same nothing happens. Useless app. Not recommended.
