I understand. Currently, I’m using the NextCloud’s extension Phonetrack, and one on my main use cases is to export GPX files to use them in Darktable and add geotracking information to the pictures I shoot with my camera. It works well, actually, but Phonetrack is not too intuitive and does not offer many other features: that’s why I was looking with interest at this alternative!

Very very cool! I see that you can import GPX files: can you also do the opposite, i.e., export a GPX file for a selected time range?
