Routing around Google Maps in Korea: Naver & Kakao deep links, weird coordinates, and iOS clipboard (opens in new tab)

If you've traveled to Korea, you've hit this wall: Google Maps can't give you walking or transit directions here. Map-data export is restricted, so locals use Naver Map or KakaoMap instead. The usual workaround for visitors is painful — copy a place's Korean name from Google, paste it into Naver, repeat for every stop. So I built K-Map Router: paste a Google Maps link → it opens that place (and the route) in Naver or Kakao. Free, no sign-up, nothing stored. Code is here: github.com/piyaklabs/...
