No configurations or data entering is needed: just open the application to immediately see the stops with the belonging lines in your area and the buses moving among them. Move or resize the map to check other areas.
At last no need to toss a coin before deciding if trying to catch a bus on one size or the other of your position: the icons on the screen will do that for you.
We made our best to localize all stops of Atac but there are presently 8033 of them; should you find no stop in the map to which you are near, you have the option of personally adding it through a button.
One last thing: although the application needs a regular functioning of the Rome transports web site in order to provide timely updates, even when the web site is down it is possible to know where stops are and which lines belong to them, what neither a direct web access, nor applications devoid of a specific back-office service would grant.
