I need to try more OSM-based apps, but so far *nothing* i've tried has been able to replace Google Maps for me for the use case of a pedestrian using exclusively public transit. The closest has been OSMAnd, which once recommended me a route that included buses that only run from midnight onward, in the middle of the afternoon, not to mention how damn long it can take to suggest a route, not very useful. Might have improved since then though, should check.
