Your first trip to South Korea will be much easier if you prepare your phone before departure.
Korea has fast public transportation, convenient taxi services, and thousands of restaurants to explore. However, many of the services that Koreans use every day operate through local apps.
The apps you normally use at home may still be helpful, but they may not always provide the most detailed Korean addresses, subway information, restaurant availability, or local search results.
As a Korean, these are the five apps I recommend installing before your first trip to South Korea:
- NAVER Map for navigation
- Kakao T for taxis
- CATCHTABLE for restaurant reservations
- Subway Korea for subway routes
- Papago for Korean translation
Each app solves a different travel problem, so you do not need to depend on one app for everything.
This guide explains what each app does, when to use it, and what you should prepare before arriving in Korea.

App functions, supported languages, and payment methods can change. Check the latest information in the app before traveling.
🚨 Crucial Pre-requisite: Secure Your Data Connection First
Before you look at the apps below, remember that tools like NAVER Map and Kakao T require real-time GPS and an active internet connection to work properly.
To use these lifesaver apps the moment you land at Incheon Airport, we highly recommend setting up an eSIM before your departure. It is much more convenient than carrying a Pocket Wi-Fi or standing in long airport lines for a physical SIM card.
💡 Recommended eSIMs for Travelers:
📱 Quick Overview of the Five Essential Korea Travel Apps
| App | Best for | When you will use it |
|---|---|---|
| NAVER Map | Directions and local place searches | Almost every day |
| Kakao T | Calling a taxi | Late nights, bad weather, or luggage |
| CATCHTABLE | Restaurant reservations and waitlists | Popular restaurants and fine dining |
| Subway Korea | Subway routes and transfers | Traveling within major cities |
| Papago | Korean translation | Menus, signs, and conversations |
🗺️ 1. NAVER Map: The Best All-Round Navigation App for Korea
NAVER Map is the first app I recommend to anyone visiting South Korea.
It can help you search for places, compare public transportation routes, find nearby restaurants, check walking directions, and locate the correct subway exit.
NAVER Map provides maps in Korean, English, Japanese, and Chinese. It also includes public transportation directions, real-time arrival information, place information, reviews, and navigation features.
What You Can Do with NAVER Map
Travelers can use NAVER Map to search for:
- Hotels and guesthouses
- Restaurants and cafés
- Tourist attractions
- Subway stations
- Bus stops
- Convenience stores
- Pharmacies
- Shopping malls
- Walking routes
- Public transportation routes
The app can also show estimated travel times, transfer information, station exits, and nearby businesses.
Why You Should Install It Before Traveling
One of the most common problems first-time visitors experience is searching for a Korean place using only its English name.
The English name listed on a travel website may be different from the name registered on a Korean map. Small restaurants and cafés may also have incomplete English listings.
NAVER Map is especially helpful because it contains detailed information about Korean businesses, public transportation, and local addresses.
International map services can still be useful for saving places or checking general locations, but NAVER Map is often more practical for daily navigation in Korea.
How to Prepare NAVER Map Before Departure
Complete these steps before your flight:
- Install the app.
- Change the app language to English.
- Search for your hotel.
- Save your hotel to your favorites.
- Save the nearest subway station.
- Create separate folders for restaurants, cafés, and attractions.
- Test the route from your hotel to your first destination.
Saving your hotel is more important than it may seem.
After a long flight, you may be tired, your mobile connection may be unstable, or you may have difficulty typing a Korean address. Having the location saved in advance makes your arrival much easier.
💡 Local Tip: Search with the Korean Name
When an English search does not work, copy and paste the Korean name.
A restaurant may use:
- An English translation
- A romanized Korean name
- A different brand name
- Only its original Korean name
Before visiting an important destination, save both its English name and Korean address.
It is also useful to take a screenshot of your hotel’s Korean address. You can show it to a taxi driver, hotel employee, or local person if you need assistance.
Check the Correct Subway Exit
Large subway stations in Seoul can have more than ten exits.
Using the wrong exit can add another 10 or 15 minutes of walking, especially at large stations such as:
- Seoul Station
- Gangnam Station
- Hongik University Station
- Express Bus Terminal Station
- Jamsil Station
- Jongno 3-ga Station
Before leaving the train, check which exit is closest to your destination.
When NAVER Map Is Most Useful
Use NAVER Map when you need to know:
- Whether the bus or subway is faster
- How many transfers are required
- Where the nearest bus stop is
- Which subway exit to use
- How long the walking route will take
- Whether a restaurant is inside a large building
- What businesses are located nearby
NAVER Map should be your main daily navigation app. The other apps in this guide can handle more specific travel needs.

🚕 2. Kakao T: A Widely Used Taxi App in Korea
Kakao T is one of Korea’s major transportation apps.
Its taxi service allows users to select a pickup point, enter a destination, request a taxi, and check the assigned driver and vehicle information.
The available taxi categories can differ depending on your city, location, and travel time. Kakao T also provides other transportation-related services, but most short-term visitors will mainly use its taxi feature.
When a Taxi Is Useful in Korea
Korea has an extensive public transportation system, but taking a taxi can still be practical when:
- You have large suitcases
- You are traveling with young children
- Your hotel is far from a subway station
- It is raining heavily
- Public transportation has stopped running
- You are traveling early in the morning
- Several people can share the fare
- Your destination is difficult to reach by bus or subway
Taxis can also be useful in smaller cities where buses and trains operate less frequently.
How Kakao T Works
The general process is:
- Open the taxi section.
- Confirm your pickup location.
- Enter your destination.
- Select an available taxi type.
- Check the estimated route or fare information.
- Request the taxi.
- Wait for a driver to accept the request.
- Check the vehicle number before getting in.
The most important step is confirming your pickup location.
The app may automatically place the pickup pin on the opposite side of a large road or near a different building entrance.
Check the Pickup Location Carefully
Before requesting a taxi, make sure the pickup pin is:
- On the same side of the road as you
- Near the correct building entrance
- In an area where cars can stop
- Outside a pedestrian-only street
- Outside a bus-only lane
- At street level rather than inside a building
At large places such as Seoul Station, COEX, department stores, and airports, there may be several taxi pickup areas.
If the driver cannot find you, move to a clear roadside location and check the license plate displayed in the app.
Important Information for International Visitors
International travelers may experience different registration, verification, language, and payment options depending on their phone number, account, card issuer, country, and app version.
Do not wait until you urgently need a taxi to set up the app.
Before your trip:
- Install Kakao T.
- Complete any available verification process.
- Check whether the app is available in a language you understand.
- Test the destination search.
- Review the available payment options.
- Save your hotel address in Korean.
- Prepare another taxi app as a backup.
A foreign-issued card may not work with every account or payment option.
If in-app payment is unavailable, check whether the app provides an option to pay the driver directly. You should also carry another payment card and some Korean won as backup.
Kakao Mobility also operates k.ride, a separate taxi service designed for international travelers. It can be a useful alternative if you have difficulty registering or paying through Kakao T.
💡 Local Tip: Avoid Unnecessary Cancellations
Once a driver accepts your request, avoid canceling unless you have a clear reason.
Canceling wastes the driver’s time, and requesting another taxi may take longer during busy periods.
Before entering the taxi, compare the vehicle’s license plate with the number displayed in the app. Do not rely only on the vehicle’s color or model.
When the Subway May Be Faster
A taxi is not always the fastest option.
During weekday rush hours, road traffic in Seoul can be heavy. A journey that looks short on the map may take much longer by taxi than by subway.
Traffic can be particularly busy:
- During the morning commute
- During the evening commute
- On Friday evenings
- During heavy rain
- Near concerts and major events
Use NAVER Map to compare the estimated taxi and public transportation travel times before deciding.

🍽️ 3. CATCHTABLE: A Useful Restaurant Reservation App
Food is one of the main reasons many people travel to Korea.
However, popular restaurants may require advance reservations or use a digital waiting list. This is where CATCHTABLE becomes useful.
CATCHTABLE allows travelers to search for restaurants, check availability, make reservations, and join waitlists at participating restaurants.
The global service is designed for international visitors and can be used without a Korean phone number. Available registration and payment options may still vary, so complete your account setup before traveling.
Make Sure You Download the Global Version
CATCHTABLE provides services for Korean users as well as international visitors.
When searching for the app, choose CATCHTABLE Global, which supports international users and multiple languages.
The domestic Korean version may require a Korean phone number or local payment method.
What You Can Do with CATCHTABLE
Depending on the restaurant, you may be able to:
- Search by neighborhood
- Search by cuisine
- Select a date and time
- Choose the number of guests
- View menus and photos
- Read customer reviews
- Make a reservation
- Pay a reservation deposit
- Join a remote waitlist
- Check reservation notifications
- Manage upcoming dining plans
CATCHTABLE lists both premium restaurants and casual local restaurants.
It can be particularly helpful for:
- Michelin-listed restaurants
- Korean fine dining
- Popular barbecue restaurants
- Trendy restaurants in Seoul
- Restaurants featured on television
- Special-occasion meals
- Restaurants with limited seating
Why Reservations Matter in Korea
Some popular restaurants fill all available tables shortly after reservations open.
Others do not accept traditional reservations but operate a digital waiting list. Instead of standing outside for a long time, you may be able to join the queue through the app.
Availability depends on the individual restaurant. Not every restaurant in Korea uses CATCHTABLE, and not every feature is offered at every location.
Always check the individual restaurant page.
Check the Cancellation Policy
Some restaurants require a deposit or prepayment.
Before confirming a reservation, check:
- The reservation date
- The reservation time
- The number of guests
- The deposit amount
- The cancellation deadline
- The refund conditions
- Whether the deposit is deducted from the final bill
- Whether all guests must arrive together
A missed reservation may result in the loss of your deposit.
If your flight arrives on the same day, avoid booking an expensive restaurant immediately after your expected arrival time. Immigration, baggage collection, airport transportation, and traffic can all take longer than expected.
💡 Local Tip: Search by Neighborhood
Searching by neighborhood is often more effective than searching across all of Seoul.
Popular dining areas include:
- Hongdae
- Yeonnam-dong
- Seongsu-dong
- Gangnam
- Apgujeong
- Hannam-dong
- Itaewon
- Myeongdong
- Jongno
- Euljiro
- Jamsil
Choose a restaurant close to the attractions you plan to visit that day.
For example, if you are spending the afternoon in Seongsu-dong, an early dinner reservation on the opposite side of Seoul may not be practical.
How to Use CATCHTABLE with NAVER Map
Before booking a restaurant:
- Find the restaurant in CATCHTABLE.
- Check the reservation time and menu.
- Copy the restaurant’s Korean name.
- Search for it in NAVER Map.
- Confirm the exact branch.
- Check the route from your previous destination.
- Allow extra travel time.
Restaurants with the same brand may have multiple branches. Make sure the branch in your reservation matches the location saved on your map.

🚇 4. Subway Korea: A Simple App for Subway Routes and Transfers
NAVER Map can already provide subway directions, but a dedicated subway app is useful when you want to understand the entire route at a glance.
For this guide, I recommend the app called Subway Korea.
It provides subway maps and route information for major Korean cities, including Seoul, Busan, Daegu, Daejeon, and Gwangju.
Its available features may include route searches, transfer information, timetables, station guides, bookmarks, and real-time transportation information.
Why Use a Separate Subway App?
NAVER Map is better for complete door-to-door navigation.
Subway Korea is useful when you want to focus specifically on:
- Subway lines
- Transfer stations
- The number of stops
- Estimated journey times
- Station exits
- Timetables
- Routes with fewer transfers
- Routes with shorter travel times
The visual subway map can also help you understand the overall structure of the transportation system.
How to Search for a Route
Enter:
- Your departure station
- Your destination station
The app will then show a suggested route.
Depending on the available options, you may be able to compare:
- The fastest route
- A route with fewer transfers
- Estimated travel time
- Transfer stations
- The number of stops
- Station information
For travelers carrying luggage, a route with one transfer may be easier than a slightly faster route with three transfers.
Learn How Korean Station Names Work
Station names are generally displayed in Korean and English.
For example:
- 서울역 — Seoul Station
- 홍대입구역 — Hongik University Station
- 강남역 — Gangnam Station
- 명동역 — Myeongdong Station
- 경복궁역 — Gyeongbokgung Station
The Korean word 역, pronounced approximately as “yeok,” means “station.”
You do not need to memorize Korean station names, but recognizing this final character can help when reading signs.
Check the Line Number and Direction
Knowing the station name alone is not enough.
Before boarding, check:
- The subway line number
- The line color
- The direction of travel
- The next major station
- The transfer station
- The final station shown on the platform display
Some subway lines divide into different branches. Two trains may use the same platform but travel to different final destinations.
Check the train’s destination display before boarding.
💡 Local Tip: Fewer Transfers May Be More Comfortable
First-time visitors sometimes choose a route with several transfers because it appears a few minutes faster.
In reality, transfers can involve:
- Long underground walks
- Multiple escalators
- Crowded passageways
- Stairs
- Waiting for another train
- Difficulty finding the correct platform
A direct route that takes five minutes longer may be more comfortable.
Subway Korea Does Not Replace a Transportation Card
A route-planning app does not function as your subway ticket.
You will still need an accepted transportation card or ticket to enter the subway system.
A rechargeable transportation card, such as Tmoney, is commonly used for buses and subways. Purchase and recharge methods can vary, so keeping some Korean won is useful as a backup.
Remember to tap your card when:
- Entering the subway
- Leaving the subway
- Boarding a bus
- Getting off a bus
Tapping when leaving a bus is important because it allows the system to calculate the correct fare and any available transfer discount.

🗣️ 5. Papago: A Practical Korean Translation App
Papago is a translation service developed by NAVER.
It is particularly useful for travelers who need help reading Korean menus, signs, notices, or short messages.
The Papago app provides several translation functions, including:
- Text translation
- Image translation
- Voice translation
- Conversation translation
- Website translation
- Offline text translation
Available functions can differ depending on your device, language pair, and app version.
When Papago Is Useful
You can use Papago at:
- Restaurants
- Traditional markets
- Convenience stores
- Pharmacies
- Hotels
- Bus stops
- Subway stations
- Ticket machines
- Tourist attractions
- Small local shops
English information is common at airports, major stations, and popular attractions. However, smaller businesses may provide limited English descriptions.
Use Image Translation for Menus
Image translation is one of the most useful Papago features for travelers.
You can photograph:
- Restaurant menus
- Food labels
- Laundry machine instructions
- Ticket machine screens
- Warning signs
- Product packaging
- Notices at your accommodation
The app recognizes text inside the image and provides a translation.
Machine translation may not correctly interpret every Korean dish name. Some food names are regional expressions or proper nouns without direct English translations.
Use the translation to understand the general meaning, and ask a staff member when you need additional information.
Use Short Sentences for Better Results
Translation apps generally work better with short and direct sentences.
Instead of writing:
I was wondering whether you might possibly have a table available for two people later tonight because we did not make a reservation.
Use:
Do you have a table for two tonight?
Other useful sentences include:
Is this spicy?
Does this contain peanuts?
Where is the nearest subway station?
Please take me to this address.
Can I pay by credit card?
What time do you close?
Translate one question at a time.
Important Advice for Food Allergies
Do not rely only on automatic translation if you have a serious food allergy.
Prepare a clearly written Korean allergy card before your trip. It should explain:
- The ingredient you must avoid
- Whether cross-contamination is dangerous
- Whether sauces or broths must also be checked
- What may happen if you consume the ingredient
Show the card directly to restaurant staff before ordering.
Papago can help with basic communication, but it cannot guarantee that a dish is safe.
Download Offline Translation Before Departure
Download the available Korean offline translation data while you have a stable internet connection.
Offline text translation can be useful when:
- Your eSIM has not activated
- Airport Wi-Fi is unstable
- You are underground
- Mobile data is slow
- You have reached your data limit
Voice, image, and conversation functions may still require an internet connection depending on the feature and app version.

❓ Frequently Asked Questions
Can I Travel in Korea Using Only Google Maps?
Google Maps can still be useful for saving places and checking general location information.
However, NAVER Map is often more practical for Korean address searches, local businesses, public transportation routes, and station exits.
Keeping both apps installed gives you an additional backup.
Does NAVER Map Work in English?
Yes. NAVER Map provides English maps and navigation, along with Korean, Japanese, and Chinese map options.
Some small businesses may still have limited translated information, so searching with the Korean place name can produce better results.
Can Foreigners Use Kakao T?
International visitors may be able to use Kakao T, but the available signup, verification, language, and payment options can vary.
Install the app and test its setup before departure. If you cannot complete the process, prepare an international traveler-oriented taxi app such as k.ride as a backup.
Do I Need a Korean Phone Number for CATCHTABLE?
CATCHTABLE Global is designed for international visitors and can be used without a Korean phone number.
Individual restaurants may still have their own reservation, deposit, cancellation, or payment policies.
Is Subway Korea an Official Government App?
Subway Korea is a private route-planning app rather than an app operated directly by the Korean government or a metropolitan subway authority.
If a service disruption or emergency occurs, check station announcements and information from the relevant transportation operator.
Can Papago Translate Korean Menus?
Yes. Papago provides image translation, which can recognize and translate text inside a photograph.
Translations of dish names and ingredients may not always be exact, so confirm important information with restaurant staff.
Do I Need All Five Apps?
You may not use every app every day.
However, installing them before departure prepares you for five common situations:
- Finding a place
- Calling a taxi
- Booking a restaurant
- Checking a subway route
- Translating Korean
✈️ Final Thoughts
