10 Useful Apps for South Korea Every Traveller Needs

Contents

South Korea is a tech-savvy country, but it runs on its own unique set of apps. Many of the apps we rely on daily in the UK simply don’t work as seamlessly here, so there are a few apps for South Korea that you should download before your trip.

When we first landed in Seoul late at night, I panicked as soon as I opened Google Maps to navigate to our hotel. Our plan was to catch the last bus as we were staying just a five-minute drive from the airport on our first night to beat the jet lag. Google Maps wasn’t working properly, and it didn’t show us how to find the bus stop – so we ended up walking around in circles, stressed.

With only a few minutes to spare until the last bus, I remembered that I had downloaded NAVER Maps – the Korean equivalent of Google Maps. Using it was effortless, and we made it to the bus stop just in time!

While there are countless apps in Korea, as a traveller, you really only need a handful to make your trip smooth and stress-free. Language barriers can make your trip challenging, but with the right apps at your fingertips, everything becomes significantly easier.

From translating menus to navigating subway lines, here’s my personal guide to the best apps for South Korea.

The essential apps for a perfect South Korea trip

1. NAVER Maps

Google Maps doesn’t work properly in South Korea due to data restrictions. It will only show public transport directions, not walking routes, and can often send you on wild goose chases.

Naver is your one stop navigation and transport app. A local favourite, it’s accurate, detailed and shows both public transport and walking routes. If you only download one app for South Korea, it has to be this one.

Once I switched to it, finding hidden cafés in Hongdae or temples in Gyeongju became ridiculously easy. You can switch the app to English and save your favourites spots.

👉 Download NAVER maps on App Store (iOS) | Google Play (Android)

2. Papago

Papago is the only pocket translator app you’ll need in Korea. If you’ve ever tried explaining food allergies in a restaurant, or just wanted to chat with a friendly ajumma at a market, Papago is your hero. Created by Naver, it’s specifically tuned for Korean, making it far more accurate than Google Translate.

Papago translation app in South Korea — I used Papago to translate a restaurant name and menu from the QR code.

I used it daily, from scanning restaurant menus to translating signs. It even handles voice and image translation, which feels like magic when you’re having a conversation with somebody.

We also received numerous weather warnings on our phones, all in Korean. I simply screenshot each message, uploaded it to Papago, and instantly had a clear English translation.

👉 Download Papago on App Store (iOS) | Google Play (Android)

3. K.Ride | Kakao T

Taxis are everywhere in South Korea, but hailing one the traditional way can be hit or miss. K.ride is the foreigner friendly version of Kakao T the popular local ride-hailing app. Kakao T itself doesn’t work for tourists and it will usually direct you to download a separate app for travellers; K.ride.

Designed specifically for visitors, K.ride accepts overseas credit cards and offers translation in over 100 languages. Both apps function like other ride-sharing services, letting you request rides straight from your phone – whether you want a standard taxi or even a bike.

I’ll admit, I downloaded both ahead of our trip but didn’t end up using them. K.ride can be more expensive than Uber, so if you already have an Uber account, it works seamlessly in South Korea without needing to switch apps or payment methods. I had no issues using Uber in Busan and Seoul, though in smaller cities there may be fewer drivers available, so it’s wise to have K.ride on hand just in case.

👉 Download k.ride on App Store (iOS) | Google Play (Android)

4. eSIM

Understandably, you’ll probably want to stay in touch with friends and family – or at least let them know you’ve landed. Thankfully, the days of queuing at the airport for a SIM card are long gone.

With Holafly’s eSIM, I had instant internet from the moment I arrived. No swapping cards, no setup drama – just activate the SIM before you leave home and switch on arrival.

Having reliable data meant I could navigate, translate and share travel photos on the go. It’s one of those small travel conveniences that makes a surprisingly big difference.

👉 Download Holafly on App Store (iOS) | Google Play (Android)

5. Korailtalk

Korailtalk is an essential app if you plan to travel across South Korea by train. It lets you check schedules, book tickets and manage reservations across the extensive Korail network, making it easy to explore beyond the major cities.

We used it to book the high-speed KTX train from Seoul to Busan, but my advice would be to book a few days in advance. We didn’t know this and booked on the day, which meant there were no seats – only standing room available on the 3+ hour train journey. And that is a long time to be stood on a train!

👉 Download Korailtalk on App Store (iOS) | Google Play (Android)

6. T-Locker App

Most metro stations in Seoul have luggage lockers, accessible daily from 5 am to midnight – basically, whenever the station is open – some are 24 hours. The T-Locker app shows available lockers nearby and offers three different sizes to choose from.

If you have a few hours to kill before a flight or train, this is an easy way to store your bags. The lockers are especially popular in Myeongdong, Seoul’s bustling shopping district, so you can explore without your shopping weighing you down. It’s a simple app, the lockers are affordable and it can save you from dragging heavy bags through crowded streets.

👉 Download T-Locker on App Store (iOS) | Google Play (Android)

7. HappyCow

South Korea’s plant-based scene has exploded in recent years, though finding vegan food in Seoul can still be a challenge. HappyCow is the easiest way to locate vegan and vegetarian spots nearby. The app provides honest reviews, photos, and directions – all in one place.

I personally use the website to plan out vegetarian-friendly restaurants before I travel, which is how I stumbled upon a café in Busan serving incredible vegan bingsu . On the go, though, the app is far more convenient – especially if you wander off your itinerary and end up somewhere less touristy.

👉 Download HappyCow on App Store (iOS) | Google Play (Android)

8. Klook

Klook is my go-to for booking tours, attractions and experiences on the go in Asia. In Seoul, I used it to book the DMZ Tour.

It’s perfect for spontaneous travellers – you can book instantly, often get discounts and sometimes skip the queues altogether. A must for last-minute planners (like me). Klook is also one of the most affordable platforms for booking experiences across Asia.

👉 Download Klook on App Store (iOS) | Google Play (Android)

9. Subway Korea

The subway system in South Korea is a marvel – clean, punctual and massive. It can be overwhelming at first glance, if you aren’t accustomed to navigating trains regularly.

The Subway Korea app is a lifesaver. It helps you plan routes, check transfer times in real time, and even shows which exit or train door to take for the shortest walk.

The app works across all major cities in South Korea and even functions offline – perfect for when your signal drops underground.

👉 Download on App Store (iOS) | Google Play (Android)

10. Shuttle

After a long day of exploring Seoul, you might just want food delivered to your hotel. Shuttle is an expat and tourist-friendly food delivery app in South Korea, featuring English menus and international payment options.

While I didn’t use it personally, it’s a popular choice among travellers thanks to its English interface and ease of use.

👉 Download on App Store (iOS) | Google Play (Android)

Why do I need extra mobile apps for South Korea?

Travelling in South Korea is incredibly smooth once you’ve got the right digital toolkit. Many of the apps we use in the UK, Europe or the US simply don’t work well there, if at all.

Preparing for a trip to South Korea isn’t nearly as daunting as travelling to China, where you often need to download and register for a host of new apps. In Korea, you only need a handful to get by.

If you’re planning your own Korean adventure, take ten minutes to download these apps before you go. You’ll probably only use two or three of them on a short trip, but you’ll thank yourself later when you’re effortlessly navigating Seoul’s streets, chatting with restaurant owners and living your best K-travel life.

Why does Google maps not work in South Korea?

Google Maps is one of my most-used apps at home and abroad – but it doesn’t work fully in South Korea due to a national security law that restricts the export of detailed map data.

South Korea requires sensitive map data to be stored on domestic servers, and Google hasn’t complied with this requirement. As a result, the government doesn’t allow Google Maps to provide full functionality, such as precise walking and driving directions. While it can still show landmarks and basic public transit information, it isn’t reliable for everyday navigation. Koreans use NAVER Maps instead of Google Maps.

The apps in this guide made my trip so much easier; from getting around to connecting with locals and uncovering hidden gems.
