Friday was the last day to use Milwaukee County Transit System's old fare collection app, Ride MCTS, according to a news release from the agency.

The transit system is now using a new app called WisGo, which is powered by Umo Mobility. The app brings a host of new features and differences from the old app. Riders will be able to purchase a 105-minute fare for $2 or a 24-hour fare for $5, according to the news release.

Once you buy a ticket, unlike the former app, your fare will become immediately active, so MCTS advises people to only purchase fares when they're ready to board the bus. It's a temporary system until new fare validators are installed on buses, the release said.

The new app is part of a wider part of MCTS's new fare collection system, which is expected to be fully up and running by the fall. The app introduces new ways to pay, and the news release touts that bus tracking will be improved.

To use the new app, look up the Umo App and enter Milwaukee as your location. While the old app is now defunct, riders will still be able to use MCards and cash to pay fares.
