Just the NYC Subway map, no bells, whistles, or other complications. From the official MTA sources, you can zoom the subway map in, zoom it out, and that's all. Very simple and easy to use! Opens to the NYC subway map immediately so you can quickly decide if you need to hop on the train in front of you, or wait for the next one. I've also tried to keep the size down so anyone can install it.
This app is excellent for visitors to NYC and longtime residents alike.
