The ATAC has allowed several private companies to sell tickets and passes for public transportation through the so-called B+ apps.
At first glance, it seems like a great solution, but it’s not the best option for short-stay visitors in Rome. None of the apps are available in English and they don’t offer a major advantage compared to the convenient Tap&Go system. However, the B+ apps may be useful for those who want to buy their tickets before arriving in Rome.
