BROOKLYN - Looking for your bus in the borough? There's an app for that.

B63 straphangers can now track their bus along its Bay Ridge-to-Cobble Hill route, thanks to a satellite-guided system unveiled on Wednesday by the Metropolitan Transportation Authority.

Commuters can check on the status of buses by using their smart phone, texting or on the Internet.

The system, called Bustime, cost the MTA $500,000 and uses a computer chip planted inside the buses to help commuters gauge when to show up at the stops.

If successful, the program will be expanded across the city.
