Very impressed with #KDEItinerary on both desktop and Linux mobile. Very easy to plan trips, and the interface once you're actually on-the-go is very information-dense in a non-overwhelming way. I can't believe I never used it before!

It can show me my whole journey on a map, my current ticket, notifies about delays, the weather... heck, even if one of my destinations has incompatible power outlets.

I also like that I can just sync it over #KDEConnect after I'm done planning on my desktop.
