Transport GZM is a free Android application designed to streamline public transportation across the Górnośląsko-Zagłębiowska Metropolia region in Poland. This app enables users to plan their journeys, track bus arrivals in real-time, and purchase tickets without needing to visit a service point. Users can set up accounts to manage discounts and access various payment methods, including credit cards and mobile payment options like Google Wallet and Apple Pay.

Key features include the ability to buy long-term tickets, such as Metrobilety, which are activated immediately upon purchase, and the innovative Start/Stop travel option that optimizes ticket pricing. Users can monitor up to five virtual bus stop displays for accurate vehicle positioning and receive notifications about their bus arrivals. The app aims to enhance convenience, making it easier for over 160 million passengers annually to navigate the extensive network of nearly 1,700 vehicles serving 56 municipalities.
