CityBus is a free Android app that provides real-time information about public transportation in Russian cities. Developed by ООО СОФТ-Центр, this app offers a range of features to help users stay informed about the current location of buses, trolleys, and trams.

Users can view transportation data on a map or in lists sorted by buses or stops. The app allows users to track the expected arrival time of transportation at a stop, taking into account current traffic conditions. Users can also save favorite stops and routes for quick access, and receive notifications when transportation is approaching a stop.

The app currently covers several cities, including Ekaterinburg, Kemerovo, Krasnoyarsk, Kursk, Norilsk, Omsk, Perm, St. Petersburg, Tomsk (electric transport only), and Zhelenogorsk (Krasnoyarsk Krai). The developers are open to working with other cities and invite interested parties to contact them through email or VKontakte to inquire about adding their city to the app.
