The official GRTA App is an excellent way to keep informed about GRTA, notifications, and schedules. The bus schedule is a core feature of this app, making it a must have for regular riders or those who are thinking about riding the GRTA buses.

Based on your choices, the app will give you the bus routes to make your trip successful. "Nihi Ta Fan Hanao" - "Let's Go Together".
