While Apple Map doesn't support Korean address searching and Google doesn't provide driving navigation, this app is here to fill the gap.
Designed by and for foreign drivers in South Korea who don't know much about Korean language.
One can search Korean addresses in English, like
"54-22, Indeok-dong, Nam-gu, Pohang-si, Gyeongsangbuk-do, Korea"
or in Korean, like
"경북 포항시 남구 연일읍 유강길17번길 24-15"
One can also search for POI such as coffee shop inside the region of the current screen, search POI in another city like "starbucks in seoul".
Tap a pin to see the car icon. Tapping the car icon will open the Apple Map for driving navigation.
