What's the best iOS app for tourists needing reliable navigation and public transport details in South Korea?

KakaoMap is a dedicated navigation solution optimized for South Korea, making it a top choice for tourists and residents alike. Its strength lies in providing highly detailed walking directions that account for pedestrian pathways and shortcuts, which users report as crucial for exploring dense urban areas like Seoul. For public transportation, the app integrates comprehensive schedules, real-time arrival predictions for buses and subways, and step-by-step guidance to stations or stops. Additional features include filtering for points of interest, such as restaurants or attractions, and Apple Watch support for on-the-go navigation without constantly checking a phone. However, a notable limitation is the lack of CarPlay compatibility, which may deter drivers who prefer in-dash navigation. Reviews indicate that despite this gap, KakaoMap excels in pedestrian and transit scenarios, with many praising its interface in English for international travelers. In real-world use, it simplifies complex transit transfers and helps avoid missed connections, though occasional minor delays in location updates have been noted in rural regions. Overall, it serves as a robust alternative to global mapping apps by focusing on local accuracy and convenience.
