I don't drive so I rely heavily on public transport, and so for me that's the biggest selling point for any such tool. Unfortunately I've yet to find an OSM app that can do this in a useful manner as Citmapper and Google do. Unfortunately the data is just not there, and when looking through the issues of AndOSM, it feels there is a lot the developers just don't want to bother implementing (and in one scenario, someone had raised a PR but they refused to merge it). Granted, some issues are due to licensing, but many are quite important from a usability point of view.
It's been a while since I last time tried AndOSM, or OSM on it's own for that matter, so unfortunately I can't remember the specific cases.
