Essential for all New Yorkers.
I’ve been using this app religiously for over 15 years. I beat every crowd to the stairs every time. I know which stairs are the quick ones (last car going to Yankee Stadium gang stand up). Every friend asks how I know where to stand on every platform, and every one is amazed by how useful this info is. I wish I could support the devs more.just for maintaining this essential repository of NYC transit knowledge.
