Works but...
Works but I hate that I have to select my line and station EVERY TIME.
I like QUICK STOP NYC better. Its more accurate and allows me to save my favorite stops so I can find times at a glance. Also, has this countdown thing that if you loaded the subway times above ground, it will keep an arrival countdown when you go underground and lose cell signal. Works pretty well.
