Out of date, DONT buy!

This last update to this app is over a year old. I loved it the first 2 years that I used it, but changes in MTA and a lack of updating have caused it to be an unreliable source for getting you around town. Plus, it doesnt offer any information about buses in any other borough other than Manhattan (which coincidentally is easy to navigate by bus without a map because its just a grid). Until they begin to update regularly, just use google maps, which will even give you scheduled subway and bus times.
