In light of complex bus routes spreading out across many cities, the “Kakaobus” app offers a new sense of orientation. It was designed to ease inconveniences for people who often use buses. Optimising the mobility of users, the app features real-time arrival information and an alarm function reminding of bus departure times. The menu tab “Suggestions” provides current location-based features, so that users may access customised information in advance. The minimalist user interface of this app features a clear colour layout, enabling users to grasp all relevant information quickly and intuitively.
