About this app

Travel smarter with the most popular and award-winning† app for trekking around Chicago public transit on the CTA.

This isn't just a bus or train tracker - this feature-packed yet easy-to-use app will revolutionize your commute and simplify your life.

IMPORTANT: Metra and Pace are NOT supported in this free version because they do not provide a bus or train tracker like the CTA.

It costs me money to host, serve, maintain, and update the data for Pace and Metra, so they must be limited to the paid version of the app.

Sorry, but thank you for understanding.

† Apps4MetroChicago app contest finalist (Transportation round).
