What is even the point of transit apps?

Seriously, I have a bone to pick with public transit apps. I mean yes, obviously they're super useful for planning routes and telling people not just that you're going to be late, but HOW late. But 9 out of 10 times, there's not a damn thing I can do but sit there and feel terrible about just how friggin' late I'm going to be. WHY TORTURE YOURSELF?
