OpenStreetMap (I use organicmaps as a client) is not a viable alternative to me when there is no reviews and no information about departure times. Are there any alternatives that are open-source?
HereWeGo probably the best till now but not open-source.
Edit: wrong spelling of OpenStreetMap
I’m usino this https://f-droid.org/packages/xyz.apiote.bimba.czwek it support external gtfs zip links. Hoping for future decision and integration in comaps
