CityBus is a free Android app developed by d.u.a.l under the Travel & Navigation category. The app offers real-time public transport tracking in various cities of Ukraine. At present, the app supports public transport tracking in over 20 cities, including Kyiv, Lviv, Kharkiv, Odesa, and Dnipro. The app depends on the functioning of an external source of GPS data, so the cooperation of the source and the app is not guaranteed. However, the app provides accurate information about the location, speed, and direction of the public transport vehicles.

CityBus offers several features, including simultaneous visualization of speed and direction of movement, color differentiation of routes, smart view, and favorites. The app filters outdated data, ensuring that users only receive relevant information. Users can save selected route lists and apply them in just a few taps on the screen. Additionally, the app allows users to search for routes by selecting two points on the map, and the results can be filtered and used to view the location of the desired transport. Overall, CityBus is a useful app for those who rely on public transport in Ukraine.
