MTS Trip Beacon gives you San Diego Metropolitan Transit System (MTS) realtime arrival times (where available). It will find the closest stops to your location and then get the arrival times to the stop quickly. It can also save two of your favorite stop numbers for quick access. This works for all bus and Trolley stops in San Diego (MTS service area).
Please make sure to close the application from the main menu by pressing the menu button and selecting "Stop This Application". The program will run in the background until you stop it or until your phone kills the app. This is a limitation of the software used to build the app.
