양산버스 is a travel and navigation app that provides bus route and stop information, as well as bus arrival times. It interfaces with the Yangsan Bus Information System to provide up-to-date information without requiring app updates. However, please note that the accuracy of bus arrival times may vary depending on the Yangsan Bus Information System.

The app offers several key features. Firstly, the Quick Info feature displays relevant information based on user preferences, such as favorite routes, time, and days of the week. This makes it convenient for users to quickly access the information they need, particularly during commuting hours.

Secondly, users can search for bus information by bus number. The app provides a route map that separates stops based on turnaround points, displaying them on both sides of the grid. Users can also check the bus schedule.

Additionally, users can search for bus arrival information by stop name or number. The app displays all buses with arrival information at the selected stop, allowing users to easily track their desired buses. The app also provides the option to view the stop location and bus arrival information on a map.

Lastly, users can add bus stops to their favorites and customize the Quick Info settings. This ensures that relevant information is displayed when the app is launched.
