Korea Travel Apps: The Ones You'll Actually Need

Your phone will do more work on a trip to Korea than your passport. It finds the subway exit, reads the menu, calls the taxi and books the train. The catch is that Korea runs on a set of home-grown apps, and some of the global apps you rely on at home behave differently here. Travellers often find this out on the first evening, standing on a street corner with a map that will not give them directions.

This guide is written by people who live here, and it follows one rule: we only name an app when an official Korean tourism or government page names it, and we tell you what that page says, not what an app store blurb promises. Nobody paid to be on this list. App features change quickly, so treat every detail as a starting point and check the app itself before you rely on it.

The short list

Maps: why your usual app may let you down

This is the change that surprises visitors most. VisitKorea's own driving guide says it plainly: the navigation (GPS) feature of Google Maps cannot be used in Korea. The same page points to two Korean alternatives that offer multilingual navigation: Naver Map, available in Korean, English, Chinese and Japanese, and Kakao Map, available in Korean and English. You can still look things up in a global map app, and plenty of visitors do, but for turn-by-turn routing you will be happier with a local one.

VisitKorea describes Naver Map as the most widely used online map among Koreans. It gives routes and travel times for walking, cycling, driving and public transport, links to opening hours and reviews for restaurants and sights, and lets you bookmark places. In 2025 VisitKorea reported that Naver had extended real-time subway information beyond the Seoul and Busan metropolitan areas and added a ferry route search, which matters if your trip includes islands.

Visitors themselves have already voted with their thumbs. In a study announced in March 2024 by the Ministry of Culture, Sports and Tourism and the Korea Tourism Organization, which surveyed foreign visitors at major airports and train stations at the end of 2023, Naver Map was the most used app for transport and route finding, and Papago led for translation.

A few habits make Korean map apps much easier. Seoul's official tourism site notes that Naver Map sometimes lacks accurate search results in foreign languages, so when an English search fails, paste the place name or address in Korean. Most hotels, restaurants and attractions publish a Korean address, and copying it from a booking confirmation into the map is the single most reliable trick we know. Save your accommodation as a favourite on the first day, and you can always route home with one tap.

Translation: menus, signs and small conversations

Papago is the translation app VisitKorea lists, and the one most foreign visitors in the government study used. According to VisitKorea it is the most widely used online translator among Korean speakers, covers 14 languages, and can read text from images, handwriting, web pages and speech, not just what you type. A nice touch for food lovers: scanning a Korean dish name can pull up VisitKorea's own food information.

Plan for moments without a signal. Visit Seoul's editors point out that in offline mode the app only handles text translation, so camera and voice features need data. If you want offline text translation as a backup, set it up before you leave home while you have fast Wi-Fi. For signs, menus and the alphabet itself, our guides to reading signs and menus and to Hangul will get you surprisingly far without any app at all.

Subway and buses: the map does most of the work

Inside a city, the map app is your transit planner. It tells you which line to take, which direction and where to transfer, and every line has both a number and a colour printed on every sign. Dedicated subway apps also exist, and Visit Seoul has featured one for its arrival notifications, but most visitors find a map app with live transit information covers the same ground.

Paying is a separate question. Most visitors use a physical transit card, and our guide to getting around explains how to buy, load and tap one. VisitKorea also lists Mobile Tmoney, a mobile transportation card app that lets you ride public transport with your smartphone instead of a card, and notes that it supports international credit cards including Mastercard, American Express and UnionPay. Whether it works depends on your phone, so check compatibility before counting on it, and keep a physical card as a backup.

Trains: book the KTX on Korail's own app

For high-speed trains, VisitKorea points to the official KORAIL platforms: the korail.com website and the KORAIL+ app, which handle reservations for KTX, SRT and tourist trains. Some VisitKorea pages still refer to the app as KorailTalk, so do not be thrown if you see both names. Tickets go on sale one month before departure from 07:00, and VisitKorea notes they can be bought until 20 minutes before departure, or even right before departure through the apps. The same page also lists Naver Train Booking and Kakao T as places to buy tickets.

Popular weekend departures do sell out, so book the trains that matter most as soon as your dates are fixed. Our KTX guide covers how far ahead to book and why fifteen minutes at the station is genuinely enough.

Taxis: hail one, or use an app built for visitors

You can still wave down a taxi on the street, and at stations and airports there are taxi ranks. Apps help when you want to see the fare estimate in advance, avoid explaining an address out loud, or get a car late at night. The app most Koreans use is Kakao T, which VisitKorea calls the most widely used taxi app. It requires a Kakao account created through KakaoTalk, and VisitKorea's guide describes registering with a local mobile number, which is the step that trips up many short-term visitors.

VisitKorea lists several alternatives designed with international visitors in mind:

• k.ride, launched by Kakao Mobility in 2024, is described as an app for foreign visitors that does not require KakaoTalk sign-up. You can register your own credit card, and the app offers English, Japanese and Chinese, with automatic translation for destinations and chat with the driver.
• TADA, according to VisitKorea, accepts an international mobile number for sign-up and a credit card for payment, in Korean and English.
• TABA was made for international tourists with support from the Seoul Metropolitan Government. You can sign up with a mobile number or a Google or Apple ID, it shows fare estimates in advance, and it is available in English, Japanese, Chinese, Thai and Russian.
• For groups or heavy luggage, VisitKorea also mentions private van services such as MOVV, booked with a credit card.

Whichever route you take, keep your destination in Korean on your phone. Showing the written address to a driver is faster and more accurate than saying it, and that applies whether you booked through an app or hailed a car from the kerb.

1330: the number every visitor should save

The 1330 Korea Travel Helpline, run by the Korea Tourism Organization, is the most useful contact you can put in your phone. Dial 1330 inside Korea, or +82-2-1330 from abroad. It offers tourist information, interpretation and a channel for tourist complaints. VisitKorea lists support in Korean, English, Japanese, Chinese, Russian, Vietnamese, Thai, Malay and Indonesian.

You do not have to make a phone call. VisitKorea lists chat through its own web messenger, which needs no download, as well as through KakaoTalk, Facebook, LINE and WhatsApp. There is also an online voice call option: no charges for calls over Wi-Fi, though mobile data charges may apply. People use 1330 for everyday problems such as a taxi driver who cannot find your hotel, a pharmacy conversation that needs a go-between, or a question about whether a site is open.

Emergencies and safety apps

1330 is for non-urgent help. In an emergency, call 112 for the police or 119 for fire and ambulance. VisitKorea advises that if you do not speak Korean, you can say "English please" or "Interpreter please" when the call connects.

The Korean government's Emergency Ready app is worth installing before you land. VisitKorea describes it as a multilingual emergency guide with disaster alerts, the locations of civil defence shelters, emergency medical centres, police and fire stations, embassy information and safety guides, plus basics such as CPR and first aid. The Ministry of the Interior and Safety announced in August 2024 that the app's foreign-language emergency alerts would expand from English and Chinese to five languages, adding Vietnamese, Thai and Japanese. VisitKorea also mentions the ministry's Baro emergency reporting app, which supports languages including English, Chinese, Japanese, Vietnamese and Filipino. Korea is a very safe place to travel, and our article on safety explains why; these apps are simply cheap insurance.

Food delivery: the honest picture

Delivery is a huge part of daily life in Korea, and it is one area where visitors often hit a wall. Visit Seoul's editors, reviewing a popular local delivery app, noted that it lacked foreign language support and that you need a Korean phone number to use it. VisitKorea, for its part, lists options that work around this: Creatrip, which it says lets you order food delivery without the hassle of verifying a Korean mobile number, and Shuttle Delivery, which delivers from local restaurants in Seoul, Pyeongtaek, Daegu and Busan.

For many short trips the simpler answer is no app at all. Korean convenience stores sell ready meals, instant noodles and coffee, many of them are open around the clock, and our convenience store guide explains how to make the most of them.

Set up before you fly

Most app frustration in Korea comes from doing setup in the wrong place: on a slow connection, at a taxi rank, with a phone number that no longer receives texts. Half an hour at home saves you that.

• Install your map, translation, train and taxi apps at home and create accounts while your home number can still receive verification texts.
• Decide how you will get online: an eSIM you install before departure, a local SIM from an airport counter, or a pocket Wi-Fi router. Our first-hours guide compares the three.
• Register a payment card in any taxi or train app in advance, and tell your bank you will be using the card in Korea.
• Switch your map app's language to English or Japanese and save your accommodation as a favourite.
• Set up offline text translation as a backup.
• Save 1330 (+82-2-1330 from a foreign number) and the emergency numbers 112 and 119 in your contacts.
• Copy the Korean addresses of your hotels into a note, ready to paste or show.

Our PDF guide Korea, The Basics collects these setup steps alongside the other first-trip essentials, if you prefer one document to a dozen tabs.

The bottom line

You do not need twenty apps for Korea. A Korean map app, a translator, Korail's app if you are taking the train, one taxi app that accepts your phone number and card, and 1330 saved in your contacts will handle almost every situation. Set them up before you fly, keep Korean addresses close at hand, and the city becomes much easier to read.
