Navigation, translation, taxis and subway โ set these up before you land, thank yourself later.
Because of local mapping rules, Google Maps in Korea is famously half-broken โ places appear, but walking and driving directions often don't. Koreans navigate with their own apps, and as a visitor you should too. These five cover 99% of a trip.
The map locals actually use. Precise walking routes, restaurant reviews with photos, subway exits numbered correctly. Switch it to English in settings and download your hotel area for offline use.
Built by Naver, it translates Korean more naturally than global rivals. The camera mode reads menus and signs; conversation mode handles ticket counters and taxi drivers. Download the Korean language pack before your flight.
Type your destination in English, watch the car arrive, pay in the app. It removes the two hardest parts of Korean taxis โ explaining where, and paying at the end. Regular taxis are fairly priced by the meter; the app just makes them effortless.
Seoul's subway is superb but vast. A route app (several good ones exist, and Naver Map covers this too) tells you the fastest car for your transfer and which exit to take โ exits matter, stations are underground cities.
Less critical for a short trip, but many tour operators, restaurants and hotels communicate through it. If you're booking experiences or meeting a local guide, having it installed saves friction.
Install all five, set the language options, and save your hotel's name in Korean as a note โ a screenshot of the Korean name and address is the single most useful thing you can show a taxi driver or a stranger you're asking for directions.
