OptiBus Leon is an Android application designed to provide real-time information for public transportation users. With this app, users can select their route and direction, and get detailed information such as the arrival time, unit number, distance, route, and number of passengers on board. They can also choose between manual or GPS location selection and get suggested routes to reach their destination.

One of the most useful features of OptiBus Leon is the visual representation of units in real-time on the route. This feature allows users to track the location of the unit they plan to board, giving them more control over their travel plans. The app is free and falls under the travel and navigation category, specifically maps and GPS.
