Official maps from the MTA, updated and movable to the SD card. The app downloads each bus map the first time you open it. Each bus map weights around 2 MB, so I recommend downloading it through a stable Wireless connection. Please, be patient with the bus maps.
Support for android versions prior to 2.3 has been discontinued.
Popup ads were removed long ago, as a response to feedback. Double banners are a bug, please let me know if it persists after update. Send me your suggestions and I''ll try to add/fix them.
