Do I need Google Maps or a Korean map app?
Walking and transit directions inside Korea are unreliable on Google Maps because of how mapping data may be exported. Most people here use Naver Map or Kakao Map, and both have English interfaces. Our own map is for finding what is on and where; for turn-by-turn directions, open the place in Naver, Kakao or Google from its page and use whichever you already have.
