Good initiative and very effective in avoiding fare-related issues with conductors. The app is simple and quick to use—no need to spend much time purchasing a ticket. Sometimes, conductors do not acknowledge passengers using this app. When the ticket is shown, a few of them simply ignore it. Secondly, the app occasionally picks the nearby bus stop as the source location instead of the actual boarding point. I hope the development team addresses these issues in their upcoming updates.

It is verry helpful to reduced queue and wandering. we can able to choose beginning date for pass validity starting. Need to be improve below: After recent update i have notice this app automatically activated bus route number through mobile location if turn On. this feature also good. but it is automatically activate some other bus if crossed near me.

The app has made booking bus, metro and suburban train tickets very convenient. You no longer have to worry about carrying the right amount of cash or change. But the bus tracking system needs to be improved. Sometimes, your nearest bus is not visible, and the map shows the bus running in the opposite direction instead of the one arriving at your stop.
