VouD is a free iPhone app developed by Autopass S.A., designed for travelers in São Paulo. It allows you to discover the schedule of transportation that passes through your preferred point or station, which gives you the opportunity to plan your trip and avoid waiting for transportation. The app is available for CPTM and bus lines in São Paulo.

One of the unique features of VouD is that it allows you to load credits for Bilhete Único and Cartão BOM, the transportation card for the Metropolitan Region of São Paulo. You can also check the balance of your Cartão BOM using this app.
