Actually, in many places in Europe Google transit directions were non-existent or useless, and apps providing similar or better functionality are very common.
* Netherlands -> 9292
* Poland -> JakDojadę + Bilkom
* Zurich -> Wemlin + SBB Mobile
* In Germany I only know the trains one, which would be DB Navigator (for some reason separate from DB Tickets).
But the new Maps lacks both bicycle AND transit directions, which means it only does, maybe 50% of what I need it for. It's basically only good for seeing where things are and where I am. It's basically useless for me for routing. No way I'm "upgrading".
Man, I miss the Maps app on Android. It even told me when I had to leave the house to make a specific bus.
