Yeah it's such an important feature to have. I don't drive a car and use public transport a lot. I use a regular old website for it which is fine, but having it included in a map app would be amazing.

I used to use Transportr

https://transportr.app/

but at some point it stopped working for the country where I live.

Organic Maps does already work for the tube in London and other metro systems. Not live information, but at least in London they run so often that it didn't matter to me. Having the route was most important and in fact multiple times gave better results than when my partner tried Google maps.

Good luck Organic Maps team! I really hope they can make it work and I'll definitely make a donation.
