Track SEPTA is a free Android app that provides real-time transit information for Southeastern Pennsylvania Transportation Authority (SEPTA) regional rail and bus services. With this app, you can get up-to-date departure times for your next train or bus at your stop, see the in-detail information about how late a train is running, and create and save routes for SEPTA regional rail.

The app allows you to save your commonly used train and bus routes and provides information about how long until the next train leaves. The user interface is simple and easy to navigate, and you can see at a glance of trains leaving soon. You can also watch your buses travel along their routes.

The app requires internet access to fetch information from SEPTA's API and AdMob ads. The developer, Keith Larson, is not affiliated with SEPTA in any way, and all data is provided by SEPTA's publicly-available API, which is subject to change or cancellation without notice. The app contains ads by AdMob, and no information is sent or saved remotely from this app, only locally on your device.

Overall, Track SEPTA is an excellent app for anyone who uses SEPTA's regional rail or bus services, providing real-time transit information to make your commute easier and more efficient.
