I am looking for an app that allows you to construct multiple-stop itinerary on + in one query :
A -- B # What is possible A -- C -- B # What I am looking for
And neither of the local networks' app that I use have that possibility.
Is there an app/website, preferably widespread (local answers are welcome nevertheless), that allow for such itinerary on public transport?
As an aside, I was wondering if there is a technical barrier to implementing such solution?
