Here’s the thing nobody tells you before a first trip to Korea: Google Maps doesn’t really work here. It won’t give you driving directions at all, and walking and transit directions are patchy. Koreans run their daily lives on a small set of homegrown apps instead — and once you have them, getting around Busan is genuinely easy. This guide walks through every essential app step by step: how to download them, switch them to English, search, get directions, call a taxi, translate a menu, and pay. It’s long on purpose — bookmark it, set the apps up before you fly, and you’ll skip the mistakes most first-timers make. For the rest of your trip, see our complete Busan Travel Guide.

1. Why you need Korean apps (and Google Maps won’t cut it)

South Korea is the rare country where the global default — Google Maps — mostly fails. For security and mapping-data reasons, Google can’t offer full driving navigation in Korea, and its walking and public-transport directions are unreliable and often out of date. You’ll search for a cafe that’s clearly there and get “can’t find a way” or a wrong location.

Locals don’t use Google Maps at all. They use KakaoMap and Naver Map, which have complete, up-to-the-minute data: every bus, every metro exit, real-time arrivals, business hours, reviews and photos. Pair one of those with a few other apps and you’ve replicated how 50 million Koreans navigate, eat, talk and pay every day.

2. The must-have apps at a glance

You don’t need dozens of apps — just this short list. Here’s what each one is for and whether it needs a Korean phone number:

Everything below explains how to actually use the big ones. Start with the maps.

3. Before you arrive: a 5-minute setup checklist

Do this at home, on Wi-Fi, before you fly — it’s far easier than fumbling with downloads at the airport:

1. Sort out mobile data Buy a Korea SIM or eSIM, or rent pocket Wi-Fi. Every app here needs internet. An eSIM you can install before departure is the easiest.
2. Download the core apps From your normal App Store / Google Play (no region change needed): KakaoMap, Naver Map, Papago, KakaoTalk, Kakao T. Add Subway Korea if you like.
3. Open each one once and set English Most have a language setting — switch it now while you have time and Wi-Fi (steps below for each).
4. Set up KakaoTalk with your phone number Verify with your home country number (it works). Do this before you swap to a Korea SIM, so the verification SMS reaches you.
5. Save your hotel Drop your accommodation into KakaoMap/Naver Map as a favorite so you can always navigate “home.”

4. KakaoMap — the complete walkthrough

KakaoMap (카카오맵) is the cleanest, most foreigner-friendly map for getting around. Here’s how to use it from scratch.

Set it to English

1. Open the menu Tap the ☰ or settings ⚙ icon.
2. Find Language Go to settings → Language and choose English. The map labels and menus switch over.

Search for a place

1. Tap the search bar at the top.
2. Type the name — in English or by pasting the Korean name. You can also paste a Korean address.
3. Tap the result to see photos, hours, phone number and reviews. Tap the star to save it as a favorite.

Get directions

1. Tap “Directions” (길찾기) on the place card.
2. Choose your mode Car, public transport, walking or bike across the top.
3. Read the transit route It shows which metro line and exit, which bus, and — crucially — real-time arrival times and total minutes.
4. Start navigation Walking mode gives turn-by-turn directions on foot, which is perfect for finding that hidden cafe.

5. Naver Map — and which map to use

Naver Map (네이버 지도) does everything KakaoMap does, and tends to have the richest place information — more photos, menus, reviews and “is it open right now” detail, because Naver is also Korea’s biggest search engine. The basics are the same:

1. Set English Settings → Language → English.
2. Search & explore Tap a place for hours, menu photos and reviews — often more detailed than KakaoMap.
3. Directions Same as KakaoMap: pick transit/walk/car, read real-time times, follow turn-by-turn.

6. Papago — translation done right

Papago (파파고) is Naver’s translator, and it handles Korean far more naturally than Google Translate. It’s your menu-reader, sign-decoder and conversation helper. Four modes you’ll actually use:

1. Text translation Type or paste Korean (or English) and get an instant translation. Tap the speaker to hear it.
2. Camera / image translation Tap the camera, point it at a menu, sign or label, and the translation appears overlaid on the image in real time. This is the killer feature for restaurants.
3. Conversation mode Two people, two languages, one phone: each speaks into their side and Papago translates aloud both ways. Great for talking to a shopkeeper or taxi driver.
4. Voice translation Speak a phrase and get it translated and read out in Korean — handy for asking directions.

7. KakaoTalk — Korea’s chat app (and why you need it)

KakaoTalk (카카오톡, “KaTalk”) is how Korea messages — practically everyone has it. As a traveler you’ll use it to reach guesthouse hosts, tour guides, and businesses that prefer Kakao over email, and to keep in touch with people you meet. It’s free over data.

1. Sign up & verify Install it and verify with your phone number (your home number works — do this before swapping SIMs). Set a profile name.
2. Set English Settings (⚙) → choose English if it didn’t auto-detect.
3. Add friends Tap the person+ icon → scan a QR code or search a Kakao ID. In person, QR is fastest.
4. Chat, call, share Free text, voice and video calls over data. You can share your live location in a chat — useful for meeting up.
5. Follow Kakao Channels Many hotels, tours and shops have a Kakao “Channel” for booking and support — add theirs for quick questions.

8. Kakao T — calling a taxi step by step

Kakao T (카카오 T) is Korea’s Uber-equivalent for taxis — you hail a regular licensed cab through the app. It shows the fare estimate up front and saves you explaining directions in Korean.

1. Install & sign in Set English in settings. You can usually register with a foreign phone number (SMS verification); if it won’t, you’ll rely on street taxis.
2. Set pickup & destination Your location auto-fills; search and tap your destination. The app shows an estimated fare and time.
3. Choose a taxi type Regular is cheapest; there are also large (van), premium “Black,” and “Comfort/모범” options.
4. Request the ride Tap call; the app matches a nearby driver and shows the car, plate and arrival time.
5. Pay Pay the driver in cash, or register a card in the app. Foreign cards work for some users but not all — having cash as backup is wise.

9. Getting around: metro, bus & transit cards

Busan has a clean, English-signed metro (4 lines plus light rail) and an extensive bus network. Your map app handles routing; a transit card handles paying.

Riding the metro & bus

1. Route it in KakaoMap/Naver Map Transit mode tells you the line, the platform direction, the exit number and real-time bus arrivals.
2. Use “Subway Korea” (optional) This app gives offline metro maps, fares and first/last train times — handy late at night.

Get a transit card

1. Buy a T-money or Cashbee card At any convenience store (CU, GS25, 7-Eleven) for a few thousand won.
2. Charge it with cash Top it up at the store counter or a station machine.
3. Tap in and out Touch the reader boarding and exiting — it works on metro, buses and even many taxis, and gives you free/cheap transfers.

10. Finding restaurants, hours & reviews (the Naver trick)

One reason Google misleads you in Korea: most restaurants and cafes aren’t on Google with correct info. They’re on Naver. To find good food and avoid turning up at a closed door:

1. Search the place in Naver Map (or the Naver app) You’ll get current photos, the menu, the phone number and two kinds of reviews — visitor reviews and blog reviews.
2. Check the hours carefully Look for 영업시간 (opening hours), 브레이크타임 (afternoon break — many places close 3–5pm), and 휴무일 (closed days).
3. Read blog reviews for the real picture Korean food blogs are detailed and photo-heavy; run them through Papago if needed.
4. Reserve if needed Popular spots use Catch Table or Naver booking; some only take walk-ins with a wait.

11. Money & payments — what actually works

Korea is largely cashless, but tourists hit a few walls because the big local pay apps need a Korean bank account. Here’s the realistic picture:

1. Default to your foreign card for most spending — it works in the large majority of places.
2. Keep cash for markets Jagalchi, Gukje, BIFF Square street food and older diners may be cash-only.
3. Withdraw at “Global” ATMs Look for ATMs marked “Global” / foreign-card friendly (in convenience stores and banks) if you need won.

12. More useful apps + troubleshooting & pro tips

Other apps worth a slot

• Visit Busan — the official city tourism app, with attractions, events and routes.
• Klook / Trazy / Trip.com — book tours, tickets and transfers (often cheaper than the gate), all in English.
• Naver Weather / Windy — accurate local forecasts (useful for beach and fireworks days).
• Google Translate — keep it as a backup to Papago, especially its camera mode.
• Coupang / delivery apps — great if you stay long, but most need a Korean phone number and address, so skip on a short trip.

Troubleshooting & pro tips

1. App store region KakaoMap, Naver Map, Papago, KakaoTalk and Kakao T are all on the global stores — no region switch needed.
2. Phone verification fails? Use your home number with the country code; if an app still refuses, ask your accommodation for help or rely on street taxis and offline maps.
3. Keep data flowing These apps need internet — keep your eSIM/SIM topped up, and download Papago and Subway Korea offline packs as a safety net.
4. Menus still in Korean? Even with English set, some content stays Korean — just point Papago’s camera at it.
5. Carry a power bank Maps, navigation and translation drain your battery fast; a small power bank saves the day.
