1. Naver Map — The Main Navigation App in Korea
According to Visit Seoul and Korea Locally, Google Maps can't provide accurate turn-by-turn navigation in South Korea due to government restrictions on high-resolution map data export. Naver Map, developed by Naver Corp (Korea's largest tech company), is the most accurate and most widely used navigation app in Korea with over 27 million monthly active users.
Why Naver Map is a must-download:
- Real-time navigation for subway, bus, walking, and driving—everything Google Maps can't do in Korea
- Real-time bus and subway arrival schedules, including crowding info
- Restaurant database with receipt-verified reviews far more comprehensive than Google
- Available in English, Japanese, and Mandarin
- Stair-avoidance feature showing elevator locations at subway stations—useful when carrying luggage
- Integrated with Papago for automatic translation of menus and reviews
2. Kakao Map — Navigation Alternative with Simpler Interface
According to Visit Seoul, Kakao Map is developed by Kakao, the tech company behind KakaoTalk. Its accuracy matches Naver Map with an interface some travelers find more intuitive. Kakao Map is very useful when someone sends a location link via KakaoTalk, as both are directly integrated.

3. Papago — The Most Accurate Korean Language Translator
