The 9 Apps You Actually Need in Korea

Korea has a strong local app ecosystem, and relying on the same map and taxi apps you use at home can leave gaps. Google Maps service in Korea is evolving, but its current coverage still does not match local apps for many driving and walking use cases. Install the essentials before your flight, then confirm that login and payment work.

How we chose

One rule: apps with a clear job in a visitor's first week. English support and registration requirements vary, so this list explains the limitation instead of promising that every feature works for every foreign account.

The list

1. Naver Map — your actual map

The national standard. Walking, driving, transit, live bus arrivals, which subway exit to use, and English search. When a local gives you directions, they're reading them off Naver Map.

Compare the options in our Google Maps vs Naver Map vs KakaoMap guide, with real screenshots and tips for choosing a route.

2. Papago — translation that understands Korean

Naver's translator handles Korean↔English better than most general tools, with camera translation for menus and signs, and a conversation mode for talking with taxi drivers or pharmacists. Works offline if you download the language pack.

3. KakaoTalk — how Korea communicates

Korea's default messenger, used by essentially everyone. Guesthouse hosts, language-exchange friends and small businesses will all say "add me on Kakao." Register with your international number before you come.

4. Kakao T — taxis with a recorded destination

Hail a taxi to your pin, confirm the vehicle and see the destination in the app. Kakao Mobility says overseas-issued Visa, Mastercard, American Express and JCB cards can be registered, but eligibility can still depend on account verification and the specific service. Keep an ordinary payment card available as a backup.

5. Kakao Map — the second opinion

Naver's rival. Some people prefer its interface; its street view and cafe/restaurant reviews sometimes cover spots Naver ranks poorly. Power move: keep both.

6. Kakao Metro — a focused subway map

A dedicated subway app is useful for line diagrams, transfer planning and checking the final train. Treat schedules as live information and confirm late-night routes on the day you travel. It pairs with our subway guide.

7. Korail Talk — intercity trains

The official app for KTX and other train tickets, with an English mode and foreign-card payment. Book Friday-evening and holiday trains in advance — they sell out.

8. Emergency Ready — offline safety guidance

The government app provides multilingual action guides for natural disasters and other emergencies. Korea Tourism Organization currently describes it as an offline safety guide and says it does not provide nearby hospital or fire-station locations, so do not rely on it as a live facility finder. See also our emergency numbers guide.

9. VISITKOREA / 1330 chat — human travel help

The official tourism service provides destination information and access to the 1330 multilingual helpline and chat. It is useful when an app cannot explain a transport problem, tourism complaint or Korean-language notice.

Honorable mentions

• Coupang Eats / Baemin for food delivery — powerful but they want Korean payment methods; details in our delivery apps guide.
• Airport Railroad / AREX app if you're taking the express train often.
• Mobile T-money — Android-with-Korean-SIM only; visitors should stick with the physical card.

How to use this list

Install 1–4 before you fly, add 5–9 on hotel WiFi the first night. Set Naver Map and Papago to English in their settings once, and you're operational. Then start on the Start Here checklist — it sequences your whole first week.
