Warsaw Bus timetable viewer
It's very crude as the only endpoints that are documented and available do not cover bus lines only stops, so the only way to use them and this app is finding the correct bus stop (and direction) and browsing available lines from there. It can be quite messy as the data is not very clean (plenty of stops with nulls or ----).
DO NOT USE THIS APP TO PLAN YOUR JOURNEY - data returned is only valid for the day of the search, so no way to get Sunday timetable if you're using the app on a weekday and vice versa.
It's barely usable but does work if you know the name of the stop you need and line number, which most of the time covers my usage so thought would share. I did reach out to the data owners if there is any way to get more endpoints to make the app more usable, but it's some 5-6 year old EU financed project with dead website and barebone minimum functionality, it's a bit of a miracle the data is still being served and accurate.
