Hmm. I did find it in the OsmAnd app, but I'm very confused. I think it's just showing me trip durations, not actual schedules, and definitely not live bus data, nor any option to find routes based on a specific departure or arrival time. For the route I tested, it gave me 4 different options, all of which list a departure time of 0:00, even though it's early afternoon here.

Digging around the other apps I use, it looks like the live transit data that I'm used to is free to access. Is there something I need to do to get that linked up?
