It allows you to track the real-time location of MCTS buses in Milwaukee and obtain accurate and up-to-date information on arrival times. With MCTS Tracker, you can enter the stop number, scan the stop's QR code, or search for the stop to get information on when the bus will arrive.

The app uses live data from MCTS to provide accurate and reliable information on bus arrival times. One of the best features of the app is its color-coded system that makes it easy to differentiate between buses and know which one you should be boarding. The app's interface is user-friendly, and the app is quick to load and easy to navigate.

It's worth mentioning that this app is not affiliated with the Milwaukee County Transit System (MCTS), and by using it, you agree to the MCTS terms of service.
