Google Maps launched bus navigation system in July, can tell you the current location, and to remind you when arriving. Pandav today launched a similar route planning application Ride NYC Subway.
Pandav is very simple to use, open the application then you can see a New York subway route map, click on the nearest subway station, and then click the subway station you want to go, the application can tell you a specific route, interval and time required to reach each station.
Main functions are as follows:

Pandav currently only launched a New York version, the future will support more subways.
