The Apps to Install Before You Fly to Korea, and the Trap Inside Each One
You have just stepped off the airport train into Seoul, and you are staring at your phone. Google Maps shows your hotel exactly where it should be, but there is no line drawn from you to it. Of 28 overseas creators who visited Korea, eight said they lost time to maps and apps, and the complaint came most often from English-speaking and German visitors. The reason is simple. In Korea, Google Maps will not walk you anywhere.
At a glance: install before you fly - Naver Map, Papago, k.ride, CatchTable Global, Emergency Ready App - all free - all can be set up without a Korean phone number - travel questions go to 1330, the tourist interpretation hotline run by the Korea Tourism Organization, open 24 hours in 8 languages.
Google's own service-coverage table lists South Korea as supported only for map tiles and place search. Driving directions, walking directions, cycling directions and live traffic are all marked unsupported. Subway and bus routes do appear, but the stretch from the station to your door is drawn as a dotted line with no guidance at all. At an interchange like Gangnam Station in Seoul, where exits run from 1 to 12, choosing the wrong one costs 10 to 15 minutes of walking back underground and up again. Three times a day is 40 minutes; over a four-day trip that is more than two hours lost on the pavement.
Make Naver Map your default. It runs in Korean, English, Chinese and Japanese, and search and directions work with no account at all. The trap is the search box: many shops will not come up under their English name, so you sometimes have to copy the Korean characters from the signboard. Booking and paying inside the app needs identity verification, and since 4 June 2026 Naver accepts a passport for that, so reservations and payments now work without a Korean phone number. KakaoMap is stronger on bus arrival times and indoor floor plans, but even set to English, parts of the screen stay in Korean. For translation, Papago, made by Naver, opens with no sign-up, and pointing the camera at a menu overlays the translation on the text. Handwritten menus and cursive signboards trip it up often.
For taxis, the smoothest option is k.ride, the foreigners-only app Kakao Mobility built separately. It runs in English, Japanese and Chinese (simplified and traditional), and you sign up with Google, Apple or email, so no Korean number is needed. Overseas-issued cards, Alipay and GrabPay all work, and destination entry and driver chat are auto-translated across more than 100 languages. Kakao T, the app Koreans use, will also accept a foreign number, but when a driver calls to confirm and there is no Korean number to answer, the ride often gets cancelled. Skip the apps and wait for an empty cab on the street, and 20 to 30 minutes is normal in a nightlife district after dark. A mid-size Seoul taxi starts at 4,800 won for the first 1.6km, but between 11pm and 2am a 40 percent surcharge pushes the starting fare alone to 6,700 won. For restaurants, CatchTable Global works in English, Japanese and Chinese and takes an email, Google or Apple sign-up. Popular tables vanish the instant booking opens, and a deposit left on a table you never visit is not refunded.
What you install before departure is not the same as what can wait. Naver Map, Papago, k.ride, CatchTable Global and the Emergency Ready App, built for foreign residents and visitors by the Ministry of the Interior and Safety, should be downloaded and logged into at home. Verification codes are sent to your home-country number, and once you swap in a local SIM card in Korea, those messages never arrive. Apps that need money attached inside Korea, such as Tmoney GO for topping up a transit card, can wait until you land. Downloading four apps on airport Wi-Fi burns 20 to 30 minutes, and those are the most expensive 20 minutes of your first day.
