The Kad ce mi bus app is a free app that allows you to see the cost of public transport for any line in Belgrade, Serbia. 

You can search for a line or add your favorite line as a favorite. You can see the timetable for the whole day and plan your departure.

You can view the details of any line, including the distance, time, and price.

The app will automatically calculate how much it costs you to get from your home to the destination you choose.

The app is useful in any case, but it is especially useful when you are at the starting station and have no idea about the timetable anywhere or you are somewhere in transport and it is important for you to know how far the bus is going.
