Your smartphone is your survival tool in South Korea. This is not an exaggeration. Korea is one of the most digitally integrated societies on earth, and apps handle everything from ordering food and paying bills to navigating the subway and communicating with professors. Students who arrive without the right apps installed find themselves unable to do things as basic as reading a restaurant menu or finding their way home.
This guide covers the 15 apps that every international student in Korea needs, organized by function. Install all of them before or immediately after you arrive. Some require a Korean phone number to register fully, so complete those setups as soon as you have a local SIM.
Communication
1. KakaoTalk (카카오톡)
What it is: Korea's dominant messaging app, used by approximately 93% of the Korean population. If you only download one app from this list, make it KakaoTalk.
Why you need it: KakaoTalk is not just for chatting with friends. It is the default communication channel for everything in Korea: professors communicate with students through KakaoTalk group chats, landlords confirm maintenance through KakaoTalk, study groups coordinate through KakaoTalk, and businesses send receipts and confirmations through KakaoTalk.
Key features:
- Group chats: Every university class, club, and dormitory floor has a KakaoTalk group chat
- Open chat rooms: Public discussion rooms searchable by topic, great for finding community groups
- KakaoPay: Integrated payment system (more on this below)
- KakaoTalk Wallet: Store digital IDs, membership cards, and coupons
- Voice and video calls: Free calls to other KakaoTalk users, including international calls
- KakaoTalk Gift: Send e-gift cards for coffee, food, and stores to friends
Setup: Download from App Store or Google Play. Register with your phone number. Add contacts by phone number or KakaoTalk ID. Set up your profile with a clear photo (Koreans use profile photos to identify contacts).
2. Papago (파파고)
What it is: Naver's translation app, far superior to Google Translate for Korean.
Why you need it: Papago handles Korean grammar and nuance significantly better than Google Translate. The camera translation feature is essential for reading menus, signs, product labels, and official documents.
Key features:
- Text translation: Type or paste text for high-quality translation between Korean and 13 languages
- Camera translation: Point your camera at Korean text for instant overlay translation
- Voice translation: Speak into the phone for real-time translation, useful for conversations
- Image translation: Upload photos of text for translation
- Conversation mode: Split-screen mode for face-to-face translation in two languages
- Offline mode: Download language packs for translation without internet
Pro tip: When at a restaurant, use camera mode to translate the entire menu in seconds. When receiving official documents (visa letters, contracts), use image translation for a rough understanding before seeking professional help.
Navigation
3. Naver Map (네이버 지도)
What it is: Korea's most accurate navigation app, significantly more reliable than Google Maps for Korean locations.
Why you need it: Google Maps works in Korea but with limited detail and sometimes inaccurate business information. Naver Map is the gold standard for Korean navigation, with precise building-level accuracy, real-time public transit information, and comprehensive business listings.
Key features:
- Public transit routing: The best route planner for subway and bus combinations, with real-time arrival times
- Walking navigation: Turn-by-turn walking directions, essential for finding specific buildings
- Business search: Restaurant ratings, hours, phone numbers, and user reviews
- Indoor maps: Detailed floor plans for major malls, subway stations, and buildings
- Street view: Korean street view for previewing locations
- Language: Available in English, though some business names remain in Korean
4. Kakao Map (카카오맵)
What it is: KakaoTalk's companion map app, the second most popular navigation app in Korea.
Why you need it: Some users prefer Kakao Map's interface, and it integrates seamlessly with Kakao T (taxi) and KakaoTalk location sharing. Having both Naver Map and Kakao Map gives you redundancy.
Unique feature: Kakao Map's real-time bus tracking is slightly different from Naver Map's, and in some areas one is more accurate than the other. Use whichever gives better results for your regular routes.
5. Kakao Metro / Subway Korea
What it is: Dedicated subway navigation apps.
Why you need it: While Naver Map handles subway routing, a dedicated subway app provides more detailed information: first/last train times for each station, real-time congestion information, exact transfer walking times, and platform information.
Subway Korea is available in English and covers subway systems in Seoul, Busan, Daegu, Daejeon, and Gwangju.
Food and Delivery
6. Baemin (배달의민족)
What it is: Korea's largest food delivery app, operated by Woowa Brothers (now part of Delivery Hero).
Why you need it: Food delivery is deeply embedded in Korean life. Baemin provides access to virtually every restaurant that delivers, from Korean fried chicken to pizza, Chinese food, sushi, and everything in between. Minimum orders start from ₩10,000-12,000 at most restaurants.
Key features:
- Restaurant browsing: Browse by cuisine, price, rating, and delivery time
- Real-time tracking: Track your delivery driver on the map
- Reviews: Detailed user reviews with photos
- Baemin 1: Premium service for faster delivery
- Payment: Card, KakaoPay, Naver Pay, or Toss Pay
Language: Primarily Korean. Use Papago's camera feature to translate menus if needed, or look for menu photos.
7. Coupang (쿠팡)
What it is: Korea's largest e-commerce platform, often called "Korea's Amazon."
Why you need it: Beyond general shopping, Coupang's Rocket Fresh service delivers groceries to your door within hours. Coupang Eats handles food delivery. The Rocket WOW membership (₩4,990/month) provides free delivery on virtually everything.
For students: Order textbooks, household supplies, electronics, and groceries without carrying heavy bags on public transit. Free returns make it low-risk to try products. For more on grocery delivery, see our grocery shopping guide.
Payment and Banking
8. KakaoPay (카카오페이)
What it is: A mobile payment service integrated into KakaoTalk.
Why you need it: KakaoPay works at most Korean stores, restaurants, and vending machines. It also enables easy money transfers between friends (essential for splitting bills) and online payments.
Setup: Activated through KakaoTalk. Link a Korean bank account or debit card. Once set up, you can pay by scanning QR codes or showing your payment barcode.
Key use case: When splitting a dinner bill with friends, the person who pays can request splits through KakaoPay, and everyone transfers their share instantly.
9. Toss (토스)
What it is: Korea's leading fintech app combining banking, payments, investment, and financial management.
Why you need it: Toss provides the clearest overview of your finances across multiple Korean bank accounts. It also offers easy domestic and international money transfers, often at better exchange rates than traditional banks.
Key features:
- Account aggregation: See all your Korean bank balances in one place
- Free transfers: Send money to any Korean bank account for free
- Payment: Toss Pay accepted at many merchants
- Budget tracking: Automatic spending categorization
- International transfer: Send money abroad at competitive rates
10. Korean Banking App (Hana, Shinhan, or KB)
What it is: Your Korean bank's official mobile app.
Why you need it: You will open a Korean bank account within your first weeks (required for receiving scholarships, paying rent, and getting paid from part-time jobs). The bank app handles transfers, balance checks, and payment management.
Recommended banks for international students: Hana Bank (하나은행), Shinhan Bank (신한은행), and KB Kookmin Bank (KB국민은행) all have experience serving international students. Some branches near universities have English-speaking staff.
Daily Life
11. Naver (네이버)
What it is: Korea's dominant search engine and internet portal.
Why you need it: Google's search results for Korean queries are significantly weaker than Naver's. When you need to find a local business, read reviews, check campus news, or search for anything Korea-specific, Naver provides better results.
Key features:
- Naver Search: The best search engine for Korean content
- Naver Blog: Korean user-generated content, especially restaurant and travel reviews
- Naver Cafe: Online community forums, including university student communities
- Naver Shopping: Price comparison across Korean online retailers
- Naver Webtoon: Korean comics, great for casual Korean language practice
12. Kakao T (카카오 T)
What it is: Korea's dominant ride-hailing and mobility app.
Why you need it: When you miss the last train, need a taxi in a hurry, or want to estimate a fare before riding, Kakao T is essential. It is also the safest way to take a taxi, as all rides are tracked and recorded.
Additional services: Kakao T also offers bike rentals, designated driver services (대리운전), and parking information.
13. Yogiyo (요기요) or Coupang Eats
What it is: Alternative food delivery apps.
Why you need them: Some restaurants list exclusively on one delivery platform. Having Baemin plus one alternative ensures you can reach virtually every delivery restaurant in your area. Coupang Eats often has exclusive promotions for new users.
Academic and Utility
14. Everytime (에브리타임)
What it is: Korea's largest university student community app.
Why you need it: Everytime is where Korean university students share information about courses, professors, campus events, used textbook sales, housing, and student life. Each university has its own verified community.
Key features:
- Course reviews: Read candid reviews of professors and courses before enrollment
- Timetable builder: Plan your class schedule with a visual timetable tool
- Community boards: Anonymous posting about campus life, study groups, and events
- Marketplace: Buy and sell used textbooks, electronics, and other student items
Setup: Requires verification with a university email address to access your school's community.
15. Weather App (Apple Weather, AccuWeather, or 기상청)
What it is: A reliable weather forecasting app.
Why you need it: Korean weather is extreme and variable. Summer monsoons, winter cold snaps, and fine dust (미세먼지) all require daily weather checking. The Korean Meteorological Administration app (기상청 날씨) provides the most accurate local forecasts, including fine dust warnings.
Fine dust alerts: Fine dust (미세먼지) and ultra-fine dust (초미세먼지) are significant air quality concerns in Korea, particularly from March to May. Check dust levels before outdoor activities and wear a KF94 mask on bad days. For more on weather planning, see our weather and packing guide.
Bonus: Honorable Mentions
Netflix Korea: Different content library from other countries, including many Korean dramas and movies with subtitles. Great for language practice.
Korail Talk (코레일톡): Essential for booking KTX and other train tickets. Includes schedules, fares, and mobile ticketing.
MangoPlate (망고플레이트): Restaurant review app similar to Yelp, with ratings and user photos.
당근마켓 (Danggeun Market): Korea's largest secondhand marketplace app (like Craigslist or Facebook Marketplace). Essential for buying affordable furniture, electronics, and household items from nearby sellers.
Setup Priority Order
If you feel overwhelmed, install these apps in this order:
Before arriving in Korea: KakaoTalk, Papago, Naver Map
First day: Kakao Metro or Subway Korea
First week (after getting Korean phone number and bank account): KakaoPay, Banking app, Coupang
First month: Baemin, Toss, Kakao T, Everytime, Naver
The digital integration of Korean society means that these apps are not luxuries. They are infrastructure. The student who has these apps configured and familiar can navigate Korea with confidence from day one. The student who does not will spend weeks struggling with tasks that take others seconds.
