TL;DR: Install three apps before you land: Naver Map for directions and transit (switch it to English in Settings), Kakao T for hailing taxis without speaking Korean, and Papago for real-time camera translation of menus and signs. Google Maps’ driving directions and local business search are unreliable in Korea, though its subway routing is a decent backup since transit data is public.

If you’ve read our guide to getting from Incheon Airport into Seoul, you already know Google Maps isn’t the tool for the job here — Korea restricts detailed map data exports for national security reasons, so driving directions, bus routes, and local business listings are all shaky at best. The good news is the local alternatives are genuinely excellent once you know which ones to grab.
Naver Map — your main navigation app
Naver Map is the closest thing to a universal answer for getting around Korea. It handles walking directions, driving, and — most usefully for visitors — subway and bus routing with real-time arrival times.
Switching it to English: On Android, open the app, tap the menu icon, go to Settings, then Language, and select English. On iPhone, Naver Map follows your device’s language setting — go to iPhone Settings → General → Language & Region → Add Language, add English, then relaunch the app. Once switched, turn-by-turn directions and subway routes display in English, though place names often show in both Korean and English at once. That’s intentional: it lets you point at the Korean name to show a taxi driver or ask a local for directions, without having to translate anything yourself.
If you skip the language setting, the app defaults to Korean and can be genuinely confusing to navigate — this is the step people miss most often.
Kakao T — hailing a taxi without speaking Korean
Kakao T is Korea’s dominant ride-hailing app, and you don’t need a Korean phone number to use it — you can sign up and verify with your home country number.
For payment, you can add a foreign card (Visa, Mastercard, JCB, and Amex are all supported), but heads up: some travelers report the payment gateway occasionally rejects a foreign card during registration, even though the same card works fine elsewhere in Korea. If that happens to you, don’t give up on the app — just select “Pay to Driver” when booking, which lets you pay in cash or by card directly with the driver instead of through the app.
Papago — real-time menu and sign translation
Papago is Naver’s translation app, and its camera feature is the one worth knowing about specifically. Point your camera at a menu, sign, or any Korean text, and it overlays the translation directly on your screen in real time — no photo-taking required, and no daily limit on this mode. (There’s a separate “photo translation” mode, capped at 50 scans a day, but you’ll rarely need it if you stick to the real-time overlay.)
There’s also a “Study Camera” mode aimed at people actually trying to learn Korean, which breaks translated text into individual words — not essential for a short trip, but worth knowing it’s there.
Worth knowing: Kakao Map exists too
Kakao Map covers similar ground to Naver Map — directions, transit, business listings — and some travelers prefer its interface. Between the two, Naver Map is generally considered the more complete option for foreign visitors, but if Naver Map ever feels off for a specific route, Kakao Map is a reasonable second opinion to cross-check against.
FAQ
Q: Should I download these before I land, or can I get them at the airport?
A: Download and set up the language settings before you fly — Incheon Airport has free WiFi, but it’s one less thing to deal with when you land tired.
Q: Does Kakao T work outside of Seoul?
A: Yes, it covers most major cities, though wait times can be longer outside the capital.
Q: Does Papago work without an internet connection?
A: No, you’ll need data or WiFi for it to work, so make sure you have an eSIM or SIM card set up first — see our SIM card vs eSIM guide if you haven’t sorted that out yet.
Q: Will Naver Map show accurate real-time subway and bus times?
A: Yes — this is one of its strongest features and is generally reliable across Seoul’s subway and bus network.
Q: Is there one app that replaces all three?
A: Not really. Each one does its specific job well, and they’re all free, so there’s little reason not to have all three installed.
Bottom Line
Three free downloads solve most of the friction of getting around Korea without speaking the language: Naver Map for getting anywhere, Kakao T for taxis, and Papago for reading anything you can’t. Set the language on Naver Map before you land, and you’re set.
