BART Usher is an official app for the San Francisco Bay Area Rapid Transit (BART) system. It provides real-time information for every station, allowing you to plan your trips and get timely notifications. It also includes a map that can be used for reference.

BART Usher is a companion app to the official website. It allows you to check the status of each station and view the current train schedule. You can also save your favorite routes and get information for any station on the route.
