Thanks! The larger fonts help. I still can't zoom in far enough to tap a specific station, unfortunately. Even my tiny fingers cover a half dozen stations in Manhattan or at least 2-3 in Brooklyn/Queens - so I get a random selection from nearby stations.

I must be missing something, though, because all it will do is show a station label when I tap a station. I've tapped several stations but don't see anything else to interact with. How are you supposed to get it to show travel times? (Using Safari on iOS 10, if that makes a difference.)
