“The fact that the Ventra app has been downloaded more than 2 million times in less than two years demonstrates why CTA is leveraging technology to improve the transit experience for our customers,” said CTA President Dorval R. Carter, Jr. in a statement. “By making transit easier to pay for and more convenient to use, we help encourage people to take advantage of great public transit in the Chicago area.”

For CTA and Pace riders, the Ventra app can be used to add value/money to their Ventra fare cards. The app is also a transit tracker for commuters to track their buses and trains. Metra riders can buy tickets via the app and keep them on their smartphones to show to conductors. It also alerts users with real-time account notifications when it’s time to purchase new passes or refill their accounts.
