Very bad
The application is missing of 2 important features:
1: edit the date and time of the photo to match the GPX file date and geotag correctly. If you need to edit it requires to BUY another application.
2: cannot export in a file format for Google Earth (kmz)
Very disappointed. Please at least incorporate the feature to edit the date and time of the photo.
