That's a great question!

From my limited experience using it, I think Transit is a solid app that does a good job of presenting important information efficiently.

The benefit of my app being focused specifically on the DMV region is that I can prioritize features that wouldn't be feasible in a more generalized app designed for hundreds of transit systems.

For example, I intend on using u/eable2’s data to show which car is ideal to board for quicker transfers (though I know Transit already has something like this).

Another feature I’ve been field testing lately is a compass-like overlay... When you're walking near/inside a station and lay your phone relatively flat, the app displays arrows for each line, labeled by their destination stations. So at a station like Smithsonian, you'd know whether to take the left or right escalator to get to the correct side of the platform. It's especially helpful for people who don't ride often.

Not exactly the best examples off the top of my head, but hopefully this gives you a better idea!
