Agency X is a transit app based on the open-source OneBusAway project. It is a rebranded version of OneBusAway, designed to showcase how the app can be customized and used in different cities. Agency X is available for free on Android devices.

The app is not intended for practical use, but rather as a tech demo. However, it does work in several cities, including Seattle/Tacoma/Puget Sound, Washington, Tampa, Florida, Atlanta, Georgia, York, Canada, Rogue Valley, Oregon, and San Diego, California. The developers plan to add support for more cities soon.

Agency X is a useful tool for developers looking to create transit apps for their cities. It demonstrates how OneBusAway can be customized and rebranded to suit the needs of different transit agencies. For more information on rebranding OneBusAway, visit their GitHub page or the OneBusAway website.
