Moovit knows where the subway train you're waiting on really is right now

Know about Waze (http://waze.com/)? It's a crowd-sourced mapping and directions app that uses each user's phone to provide realistic directions, suggestions, and up-to-date maps. Moovit wants to be the Waze of public transit, giving people real data on which bus or train to take, but also how crowded or late it is inside each unit--and whether the Wi-Fi is actually working.
