It's there. For today:

Maybe you did choose a different departure point than the harbour...

I had the wrong Bari. Thanks

You should only add journeys where you get a 100% discount on the ticket to your Trip. Days when you travel on ferries where you only get a discount on the ticket should not be added in  the app. If you have a flexi pass you risk loosing travel days if you wrongly add ferries in the app.

I have a 2 month global pass so that's not really a problem for me. One of the nicest features of the app is the map/stats. It's a shame you're not able to log none pass journeys in it.

Here is my recent travel day in the swiss alps mostly without InterRail:

And here is the statistic page for the routes taken by swiss Postauto which is not included with IR:

You see, it's possible (you just need to have a timetable for the non pass trip).
