These files contain only some data from the tracker messages and there is no information about stops, since stops are determined in our application based on speed and other data.
We do not have a special application for viewing information from these files. However, there are many tools to do this on the internet. For example, for kml files, you can use Google Earth or another program.
If you have any suggestions for improving the ability to work with the export of tracks, then we will be glad if you write to us about them.
