Können Sie GPX-Dateien aus einer anderen Anwendung in Cyql öffnen/importieren?

Yes indeed! It is possible to open .GPX files in Cyql from any app (e.g. Komoot) or website where .GPX files can be shared or downloaded, and create a ride directly with them. To do this, click on the corresponding .GPX file and then select the Cyql app in the list of possible apps on your device with which a .GPX file can be viewed.
