What's a good Android app for buying train tickets ahead of time? Seems like it would save a lot of hassle, especially on those crowded Friday afternoons after school lets out.

So, I started using this MTA TrainTime app a few months back, and it's actually been a lifesaver. You see, I take the train into the city sometimes for conferences and, well, just to get out of Ohio. And trying to buy a ticket at the station when everyone's rushing around? Forget about it! This app lets you buy your ticket beforehand, right on your phone. Took me a few days to figure out all the features, I'll admit, but once you get the hang of it, it's surprisingly intuitive. It's like having a teaching assistant in your pocket, reminding you to get your ticket before the bell rings, so to speak. My students actually showed me this trick for quicker payment – why do they hide the settings button there, though? Anyway, beats digging around for cash and hoping the machine isn't out of order. Definitely makes those trips a little less stressful, especially after a long week grading papers.
