Okay, what's a good Android app for figuring out exactly when the next train's coming when I'm heading home after a crazy long shift?

Honestly, after a 12-hour shift, I'm too tired to learn complicated apps. I just need something that *works* when I need it. The NJ TRANSIT Mobile App has been pretty great for that. I use it all the time to check when the next train is coming into Union Station. It's got a no-fuss approach, which I appreciate. The real-time updates are like having a pocket reference guide for the train schedule. I even showed some of the other nurses at County how to use it; they're always running late, too! The best part is, it's actually reliable. It hasn't crashed once in the six months I've been using it, which is a lifesaver when you're relying on it to get home.
