Avtobus Sumy is a mobile application developed by GPS-технології for monitoring the public transportation in Sumy, Ukraine. With this app, users can track the location and movement of buses on their desired route, as well as check the expected arrival time of the bus at their stop. Currently, not all buses are being displayed on the routes due to ongoing device restoration, but new units are being added every day.

The app also provides a list of all routes passing through the selected stop, but the data is incomplete in some cases where there is no information about the movement of the bus. The number of stops with available forecasting is constantly increasing. The app offers features such as switching between route and stop lists, selecting favorite routes or stops, and displaying only selected routes or stops. Users can also view the arrival forecast and schedule for their chosen stop by selecting it from the list or by clicking on the stop during the route view.
