Which apps do you actually need for a trip to Korea? Fewer than you might think. Eight apps cover almost everything a visitor does: finding your way, calling a taxi, reading a menu, booking a train and getting help if something goes wrong.
The catch is timing. Several of these apps want an account, a card or a text-message code, and that's much easier at home on Wi-Fi than at an airport gate at midnight. So this guide is built around one idea: set things up before you fly.
Each app below has a short intro and a QR code. On a laptop, scan the code with your phone. On a phone, just tap the download link under the code.
At a Glance
- Maps: use Naver Map or KakaoMap. Google Maps still can't give step-by-step walking or driving directions in Korea.
- Taxis: k.ride is made for international visitors. Kakao T is the app most Koreans use.
- Language: Papago translates menus and signs with your camera, in 14 languages.
- Trains: Korail Talk is now called KORAIL+, and it's the official app for KTX train tickets.
- Safety: the government's Emergency Ready App sends disaster alerts in 22 languages. Save 1330 (travel hotline) and 119 (fire and ambulance).

First, Why Google Maps Isn't Enough in Korea
This surprises a lot of visitors. Google Maps works in Korea, but only partly. It shows places, reviews and public transit routes. It doesn't give turn-by-turn walking or driving directions. The walking parts of a route show up as dotted lines.
The reason is map data. For years, Korea didn't allow its detailed government map data to be taken to servers abroad, citing security. In February 2026 the government approved Google's request with conditions, and Google has said full navigation is coming. As of late September, the government's review of how Google will meet those conditions was still ahead, and no launch date had been given.
So here's the practical split: keep Google Maps for saving places you find while planning at home. On the street, use a Korean map app.
Maps: Naver Map and KakaoMap
1. Naver Map (네이버 지도)
If you install only one app for Korea, make it this one. Naver Map is the map most Koreans use, and its app listing says it offers Korean, English, Japanese and Chinese maps, plus English navigation.
What you'll use most:
- Transit directions with real-time departure and arrival times
- Get-off alerts, so you know when your stop is coming
- Walking routes, which Google can't give you here
- Bookmarks, to save restaurants and sights before your trip
One tip saves a lot of frustration: search in Hangul (the Korean alphabet) when you can. English spellings of places vary, so copy the Korean name of your hotel or restaurant from its website and paste it in.

2. KakaoMap (카카오맵)
KakaoMap is the other big Korean map, made by the company behind KakaoTalk. Its App Store listing shows English and Korean.
Think of it as your backup. It covers walking, public transit, cycling and driving routes, real-time bus arrivals and a subway map. When one app's route looks odd, checking the other takes ten seconds.

Taxis: k.ride and Kakao T
Both apps come from Kakao Mobility, and both call licensed Korean taxis. The difference is who they're designed for.
3. k.ride
k.ride is the easier start for most visitors. Korea's tourism board describes it as a mobility service exclusive to international visitors, and you don't need a KakaoTalk account to use it.
- Sign-up: phone number, email, Google or Apple account
- Payment: credit or debit cards issued abroad, plus Alipay+ and WeChat Pay
- Language: the app runs in English, Japanese and Chinese (simplified and traditional). You can search destinations and chat with the driver in 133 languages, with automatic translation
- Fare: you see an estimated fare before you call the taxi
In-app customer support runs from 9 a.m. to 2 a.m. Korea time, according to the app listing.

4. Kakao T (카카오 T)
Kakao T is the taxi app most Koreans use, and it works across the country, Jeju Island included. The app is available in English, Japanese and Korean, and it shares the driver's name and plate number for your safety.
The trade-off is setup. Korea's tourism board says you first need a Kakao account, which you create through KakaoTalk (Korea's main messaging app). That step involves phone verification, so try it at home.
Payment has a simple fallback. Before you confirm a ride, you can pick Pay to the driver and pay in the car with cash, a card or a T-money card. That's handy if adding a card in the app doesn't work for you.
Whichever app you use, check the plate number before you get in. If you've already paid in the app, you shouldn't pay again in the car.

Translation: Papago
5. Papago (파파고)
Papago is Naver's translator, and Korea's tourism board calls it the most widely used translator app among Korean speakers. It covers 14 languages, including English, Japanese, Chinese, Spanish, French, Vietnamese, Thai and Indonesian.
The three features travelers use most:
- Image translation: snap a menu, a sign or a product label
- Conversation mode: you and the other person each speak your own language
- Offline text translation: useful in a subway tunnel or when data runs out
A translator won't replace a few polite words, though. Our Must-Know Korean Expressions cover the ones people use every day.

Trains and the Subway
6. KORAIL+ (코레일플러스, formerly Korail Talk)
Looking for Korail Talk? It's been renamed. The app's own update notes say Korail Talk "has been renewed as KORAIL+." It's the official app of Korea Railroad Corporation, the operator of the KTX high-speed train.
You can search trains, book seats and keep your tickets on your phone. The listing also says you can book tourist trains and the Korail Pass, a rail pass for non-Korean citizens. Korea's tourism board says the Korail+ app and the Let's Korail website (letskorail.com) cover reservations for trains including the KTX and SRT. The app lists multiple languages, which Korail says are there to make booking easier for foreigners.

Do you need a separate subway app? Usually not. Naver Map and KakaoMap already handle subway routes, transfers and arrival times. What you do need is a way to pay: most visitors tap a T-money (티머니) transit card at the gates and on buses. Our Seoul subway guide explains how to buy and top up T-money, and when Seoul's Climate Card (기후동행카드) pass is worth it.

Travel Help: VISITKOREA and 1330
7. VISITKOREA
This is the official app of the Korea Tourism Organization, Korea's national tourism board. It's available in eight languages: English, Japanese, Simplified and Traditional Chinese, German, French, Spanish and Russian.
It's best for planning and ideas: attractions, food, festivals, a travel planner and suggested itineraries. The Travel Basics menu lists emergency contacts, and the app includes subway maps for Seoul, Busan, Daegu, Gwangju and Daejeon.

1330 Korea Travel Hotline isn't an app, but save it anyway. Call 1330 in Korea, or +82-2-1330 from abroad, for travel information and interpretation help. Korea's tourism board lists Korean, English, Japanese, Chinese, Russian, Vietnamese, Thai, Malay and Indonesian. A useful trick: put 1330 on speaker when you're stuck at a shop counter or a taxi stand.
Safety: Emergency Ready App and 119
8. Emergency Ready App
This free app comes from Korea's Ministry of the Interior and Safety. It's the foreigner version of the government's disaster-alert app.
The headline number: since a June 2026 update, it covers 22 languages, up from three. You get emergency alerts for things like typhoons, earthquakes and heavy snow, plus the nearest shelters, emergency medical centers, police and fire stations, embassy contacts and a one-tap 119 call.
One thing to watch: the stores still list an older version named "(Old)Emergency Ready App." Download the one without "(Old)" in the name. The QR codes below point to the current one.

For a real emergency, call 119 for fire and ambulance. The 119 ambulance is free, foreigners included. If you're wondering what a clinic or ER visit costs, see our guide to medical costs for tourists.
Payment and Food Delivery, Briefly
Cards work in most shops and restaurants, so you won't need a payment app for daily life. Two visitor-friendly options are worth knowing:
- WOWPASS: a prepaid card and app for international travelers that combines a transit card with a debit card. You load it at exchange kiosks or in the app.
- Mobile Tmoney (모바일티머니): a transit card inside your phone. Korea's tourism board says it supports international Mastercard, American Express and UnionPay cards.
Food delivery is possible too. Korea's tourism board lists Shuttle Delivery, an English-language service in parts of Seoul, Pyeongtaek, Daegu and Busan. For the big Korean delivery apps and what works with a foreign card, see our deep dive on travel apps with a foreign phone and card.
A Quick Note on Data
Every app here needs mobile data. Your main choices are roaming with your home carrier, an eSIM (a digital SIM you install on your phone before you leave) or a physical SIM bought on arrival. One detail matters: a data-only plan won't give you a phone number. That's fine for maps and Papago, but keep your home number able to receive texts if an app sends you a verification code.
Set Up Before You Fly: Checklist
Do this at home on Wi-Fi, a few days before your trip:
- Install Naver Map and KakaoMap. Bookmark your hotel using its Korean name.
- Install k.ride, sign up and add a payment method.
- Want Kakao T as a backup? Create your Kakao account through KakaoTalk first, while your home number can get texts.
- Install Papago and try the camera mode once.
- Taking the KTX? Install KORAIL+ and look up your route.
- Install VISITKOREA and the Emergency Ready App (not the "(Old)" one). Allow notifications for alerts.
- Save 1330 and 119 in your contacts.
- Sort out roaming, an eSIM or a SIM.
- Screenshot your hotel's Korean address, in case your battery or data dies.

FAQ
Q. Does Google Maps work in Korea?
Partly. It shows places, reviews and public transit routes, but not turn-by-turn walking or driving directions. Google says full navigation is coming but hasn't given a date. Use Naver Map or KakaoMap on the street.
Q. What's the best taxi app for tourists in Korea?
For most visitors, k.ride. It's built for international visitors, takes cards issued abroad, and translates your chat with the driver. Kakao T has more users but needs a Kakao account first.
Q. Is Korail Talk still available?
It's been renamed KORAIL+. If you already have Korail Talk, updating the app gets you KORAIL+.
Q. Do I need a Korean phone number for these apps?
Not for most of them. Maps, Papago, VISITKOREA and the Emergency Ready App work without one, and k.ride lets you sign up with email, Google or Apple. Apps that send a text code need a number that can receive SMS, which can be your home number.
Q. Is Papago better than Google Translate for Korean?
Both work. Papago is Naver's app and the one Korea's tourism board says Korean speakers use most. It's worth having for menus and signs, and its text translation also works offline.
Q. What number do I call for help in English?
Call 1330, the Korea Travel Hotline, for travel help and interpretation (+82-2-1330 from abroad). For fire or an ambulance, call 119.
