OnBoard is a free Android app developed by OnBoard Mobility that allows you to recharge your SINGLE TICKET for public transportation, such as subway, train, and bus, without the need to queue at the box office. With the app, you can also recharge prepaid cell phones from various Brazilian operators, including Claro, Vivo, Oi, and Tim On-Line, among others.

The app offers several credits options, including Bilhete Único Comum, Estudante/Professor, Diário, and Mensal. In addition, OnBoard provides a customer support service, where problems and doubts are solved instantly. The app also grants access to your purchase history and shows the nearest validation points for the SINGLE TICKET recharge.

OnBoard allows you to make your purchases safely and quickly with a credit card or Ticket Car. It is a lightweight app, less than 5MB, which makes it compatible with any smartphone.

One important feature to consider is the R$4 fee charged for Ticket Car recharges; otherwise, there are no fees for credit card payments.

Overall, OnBoard is a practical, fast, and secure app, making it an excellent option for those who need to recharge their SINGLE TICKET or prepaid cell phones in Brazil.
