- running mobile app
- users should be able to
	- plan public transport in the VBB transit network
	- create and customise routes quickly and on-the-fly
	- edit routes from anywhere, where respective route information can be seen
	- compare routes easily, especially between different endpoints
- the app should offer up the information most relevant to current route planning
	- between route steps, there should be no more than 3 taps required, optimally even just one(1), scrolling excluded
	- e.g. only lines that connect to a station should be shown
	- stations that a line goes through should be available as next node/ step for planning
