Here’s the thing nobody really warns you about with South Korea. The phone you rely on at home suddenly becomes about 60% useful.
Google Maps can’t walk you anywhere. The taxi app everyone uses wants things you probably don’t have. Half the restaurants worth queuing for have a digital queue you didn’t know existed. And your bank card, the one that works everywhere, gets politely rejected at the subway gate.
Korea is one of the most connected countries on the planet. It just runs on its own apps.
The good news? Get them set up at home, on your sofa, on WiFi, with a brew, and you’ll land feeling like you’ve lived there for years. Leave it until Incheon arrivals and you’ll spend the first two hours of your precious annual leave fighting verification codes. Ask me how I know the general vibe of that.
This is the list I’d hand any 9-5 traveller of the essential apps for South Korea who doesn’t want to waste a single day of their holiday working out how to get a taxi.
The short version: if you only download five, make it Naver Map, Papago, Kakao T (or K.ride), WOWPASS and an eSIM. Everything else makes the trip smoother. Those five make it work.
1. Naver Map: your new Google Maps
Let’s get the big one out of the way. Korea restricts the export of its detailed map data, which is why Google Maps here shows you places and transit but won’t give you proper walking or driving turn-by-turn directions.
That might change. In February 2026 the Korean government conditionally approved Google’s request to export high-precision map data, and Google has confirmed it plans to bring full navigation to Korea. There’s no launch date yet though, so for now it’s not something to build a trip around.
Naver Map is what locals actually use. It has an English map edition and English navigation, real-time bus and subway info, and walking routes that know the shortcuts through alleys and underground passages.
Why you need it: it’s the most accurate way to get around, full stop. It also shows menus, opening hours and reviews, and some places let you book directly through Naver Reservation.
Setup tip: switch the language to English in settings, then bookmark your hotel, the airport and your must-visit spots before you fly. If a place won’t show up, search the Korean name instead. Results are noticeably better in Korean. Still choosing a base? Here’s where to stay in Seoul, area by area.
2. Papago: the translator that actually gets Korean
Papago is made by Naver and built specifically for Korean, including the politeness levels that trip up generic translators. It’s consistently more natural than Google Translate for Korean.
Why you need it: camera mode reads menus, signs and packaging in real time. Conversation mode handles the back and forth with a taxi driver or shop owner. And the half-translated Korean phrases you copy into Naver Map searches? Papago is where they come from.
Setup tip: download the offline Korean language pack before you go, so it still works in a basement restaurant with no signal.
Honest bit for halal and pork-free eaters: learn to spot 돼지 (pork). Pork turns up in a lot of Korean dishes, including ones you wouldn’t expect, and scanning a menu with Papago is the quickest first check.
3. Kakao T (and K.ride): getting a taxi without the drama
Kakao T is the dominant taxi app in Korea, basically the local Uber. It has an English interface, and Kakao’s own payment FAQ lists foreign-issued Visa, Mastercard, JCB and Amex cards as accepted for regular taxi rides.
The catch: phone verification with a non-Korean number is hit and miss. Some travellers sail through, others get stuck on a code that never arrives.
The fix: K.ride, Kakao Mobility’s app built specifically for foreign visitors. You can sign up with a Google or Apple account and pay with an overseas card, and it plugs into the same taxi network.
Setup tip: download both, try Kakao T first, and do the whole verification and card setup at home while your phone is still on your home network. If all else fails, you can still hail a taxi on the street. Most take cards.
4. WOWPASS: the card that fixes Korea’s payment weirdness
This is the one people skip and then regret. Korea is very cashless for locals, but the big local wallets like Kakao Pay and Naver Pay want a Korean phone number and bank account, and some card terminals and most Korean online shops reject foreign cards. On top of that, your contactless bank card won’t work at most subway gates.
WOWPASS is a prepaid card and app made for foreign visitors. It combines currency exchange, card payments and a built-in T-money transit card. You load it at kiosks in the airport and subway stations, and it takes 16 currencies, so you can feed it pounds.
Why you need it: one card for the subway, buses, taxis, convenience stores and shops, and the app shows your balance in real time. Lose the card and you can freeze it from the app.
Honest bit: the transit balance is separate from the spending balance. Top up both before you hit the subway, or you’ll be the person holding up the queue at the gate. (Every trip has one. Don’t let it be you.)
5. An eSIM app: be online before the plane door opens
Nearly every app on this list needs data, and several need it the second you land. Rather than queuing for a SIM at Incheon or paying roaming fees, set up a Korea eSIM before you leave. Get an Airalo eSIM for South Korea here.
Why you need it: taxis, maps, translation and payments all go live the moment you switch your phone on.
Setup tip: install the eSIM at home but only activate the data plan when you land. Keep your normal SIM switched on for calls and texts, because a lot of Korean apps send verification codes to your home number.
6. Korail+ (formerly KorailTalk): KTX trains made simple
If you’re heading beyond Seoul, and you should, the KTX bullet train gets you to Busan in under three hours. Korail’s booking app was renamed from KorailTalk to Korail+ in August 2026 as the Korail and SRT booking systems merge, so don’t panic if the app looks different to the screenshots in older blogs.
Good to know: from 1 October 2026, KTX tickets go on sale 60 days before departure instead of 30, which is great news if you plan your annual leave months ahead like me. You can also book through Korail’s English website or through Klook, which started selling KTX tickets under a deal with Korail.
Setup tip: popular weekend and holiday trains sell out. Book as soon as your dates are locked in.
7. Subway Korea: the metro cheat sheet
Naver Map handles subway routes perfectly well, so this one’s a nice-to-have rather than essential. But Seoul’s metro is enormous, and Subway Korea is the cleanest way to see the whole network at a glance.
Why you need it: full subway map, routes between any two stations, journey times, fares, and first and last train times. That last one matters more than you think after a late night in Hongdae.
8. CatchTable Global: skip the two-hour queue
Korea’s restaurant scene runs on reservations and remote waitlists, especially anywhere that’s gone viral. CatchTable is the country’s biggest booking app, and the Global version is built for tourists.
Why you need it: you can sign up with just an email, pay with an overseas card, and it works in around 20 languages across more than 12,000 restaurants. Plenty of places only take bookings through the app, and the waitlist feature means you can wander off and come back when your table’s ready instead of standing outside in the cold.
Setup tip: make sure you download CatchTable Global, not the local version. The icons look almost identical. Not every restaurant is on the global app, so if somewhere’s missing, check Naver Map for booking options.
9. MUFKO (Muslim Friendly Korea): halal food and prayer rooms
This one’s personal. I eat halal, and while Korea is getting easier every year, it’s still a country where pork and alcohol are woven into a lot of the food culture.
MUFKO lists halal restaurants by five standards (Muslim certified, self-certified, pork free, veggie and seafood), maps more than 180 prayer rooms and masjids across Korea, and gives prayer times and qibla direction based on your location.
Honest bit: not all labels mean the same thing. The Korea Tourism Organization uses a four-tier system, and “Muslim friendly” can simply mean some dishes are halal, with soju on the next table. If certification matters to you, look for Korea Muslim Federation (KMF) certified places or established Muslim-owned spots, many of them around Itaewon.
Also worth a look: Halal Korea, a free English-language app with nearby halal restaurants, prayer times and mosque locations, plus the official VisitKorea Muslim-friendly directory.
10. KakaoTalk: how Korea actually communicates
KakaoTalk is Korea’s WhatsApp, and pretty much everyone uses it, from guesthouse hosts to tour guides to the shop holding your order.
Why you need it: if a business gives you a contact, it’ll usually be a KakaoTalk ID, not a phone number. Having an account also gives you a Kakao login, which smooths things over with Kakao T.
11. Klook: tours, tickets and transfers in one place
Klook is where I’d book the bigger-ticket stuff: DMZ tours, palace and attraction tickets, airport transfers and even KTX tickets. It’s all in English, takes foreign cards, and sends e-tickets straight to your phone. Browse Klook’s Seoul tours and tickets here.
Why you need it: it saves you wrestling with Korean booking sites for anything that needs to be locked in before you land.
Honourable mentions
- Shuttle: a food delivery app built for foreigners. Fully in English, no Korean number needed, with everything from Korean BBQ to Middle Eastern food. Ideal for the night you’re too jet-lagged to leave the hotel.
- Google Maps: keep an eye on it. Full navigation is coming, but until it actually launches, Naver Map is still the one.
Your pre-flight setup checklist
Do all of this at home, on WiFi, before you pack a single outfit (and if you’re still deciding on outfits, here’s what to wear in Seoul):
- Install your eSIM (don’t activate the data plan yet)
- Download Naver Map and KakaoMap, set to English, and bookmark your hotel and the airport
- Download Papago and its offline Korean pack
- Set up Kakao T and K.ride, verify your number and add your card
- Download the WOWPASS app (you’ll pick up the card on arrival)
- Book KTX tickets on Korail+ or Klook if you’re leaving Seoul
- Download CatchTable Global and save any restaurants you’re desperate to try
- If you eat halal, download MUFKO and save a few options near where you’re staying
Final thoughts
Korea rewards the traveller who does their homework. Spend one evening setting these apps up and you’ll walk out of arrivals already knowing how to get a taxi, pay for the subway and find dinner. Skip it and you’ll spend day one learning the hard way.
Your annual leave is too precious for that. Download the apps, then go and enjoy the place.
Once your phone is sorted, plan the trip itself: start with my 4-day Seoul itinerary built around annual leave, use my 5-point filter if your wish list is already five pages long, and check the South Korea travel guide for visas, weather and festivals.
FAQ
Does Google Maps work in South Korea?
Only partly. It shows places, reviews and public transport, but not proper walking or driving turn-by-turn directions. Korea conditionally approved Google’s map data request in February 2026, but there’s no launch date yet. Use Naver Map or KakaoMap instead.
Can I use Kakao T without a Korean phone number?
Often, yes. Kakao T accepts foreign Visa, Mastercard, JCB and Amex cards for regular taxis, but verification with a foreign number doesn’t always work. If it fails, use K.ride, Kakao Mobility’s app for foreign visitors, which lets you sign up with Google or Apple.
Do I need cash in South Korea?
Very little. Korea is largely cashless, but foreign cards don’t work everywhere, including at most subway gates. A WOWPASS card covers transport and most payments, so you only need a small amount of cash as backup
What’s the best translation app for Korea?
Papago. It’s made by Naver specifically for Korean and handles context and politeness levels far better than general translators. Download the offline language pack before you go.
Do UK citizens need a K-ETA for South Korea?
Not right now. UK passport holders are exempt from the K-ETA until 31 December 2026. If you’re travelling in 2027, check the latest rules before you book, as the exemption has been extended year by year.
How do I find halal food in South Korea?
Use MUFKO or Halal Korea to find certified and Muslim-friendly restaurants and prayer rooms near you. For the strictest standard, look for Korea Muslim Federation (KMF) certification. Itaewon in Seoul has the highest concentration of halal restaurants.
