The apps you relied on back home will only get you part of the way in Korea. The phone in your pocket runs daily life here — paying, getting around, ordering food, talking to landlords and offices — but the most useful apps are Korean-made and not always the global names you know. Installing the right ones early saves a surprising amount of frustration.
This guide covers the categories that matter most and the specific apps locals actually use, including a few that need a Korean number and identity verification before they fully work. Set these up once and most of the friction of living here quietly disappears.
Why global apps fall short here
Some international apps simply underperform in Korea. The most famous example is maps: Google Maps has limited walking and driving directions within Korea due to local data restrictions, so locals rely on home-grown maps instead. Other foreign services either are not localised, do not accept Korean payment methods, or are not what local shops, drivers and offices use. The practical answer is to adopt the Korean equivalents rather than fight the gaps.
Maps and navigation
For getting around, install Naver Map or KakaoMap. Both give reliable walking, driving, transit and bus directions, real-time arrivals, and search that actually finds Korean businesses. They are the apps you will open many times a day, so it is worth getting comfortable with one of them early.
Messaging
KakaoTalk is essential. It is the default messaging app for nearly everyone in Korea, used not only between friends but by businesses, delivery services, landlords and customer support. Many services send confirmations and notices through Kakao, so even if you prefer another messenger socially, you will want Kakao installed to function here.
Transit and taxis
Naver Map, KakaoMap and dedicated subway apps cover public transport routing and live timetables. For taxis, Kakao T is the standard ride-hailing app — you can call a regular or premium taxi and often pay in-app. To tap through the gates on the subway and bus, you will also want a transport card; see our guide to using T-money and public transport.
Delivery and shopping
Korea's delivery culture is world-class. For restaurant food, Baemin (배달의민족) and Coupang Eats are the leading apps. For groceries and general shopping with famously fast delivery, Coupang is the go-to. Most of these need a Korean phone number, an address, and a payment method to check out, so set up your banking and a card first.
Payments
Mobile payment is everywhere in Korea. The main apps are Kakao Pay, Naver Pay and Toss, which let you pay in stores and online, send money to friends, and split bills. They tie into your Korean bank account or card. We cover setup and differences in our guide to mobile payment apps in Korea.
Translation
Papago, made by Naver, is the translation app most foreigners and locals trust for Korean — it handles text, voice, image and conversation translation well. Keep it handy for menus, signs, documents and conversations with offices. It often outperforms general translators on Korean specifically.
Government and admin
For official tasks, the Government24 (정부24) portal and app give access to many civil services and documents. Banking apps from your bank, and certificate apps, also live in this category. Many of these are the ones most likely to demand identity verification before they let you in.
A note on verification
A large share of these apps — banking, payments, government, even some delivery and shopping services — require Korean identity verification (본인인증) to register or to unlock full features. That almost always needs a Korean phone number registered in your own name. If apps keep rejecting you at sign-up, that is usually why; read our verification guide for the fixes.

Wrapping up
Start with a map app, KakaoTalk and Papago on day one, then add Kakao T, a delivery app and a payment app once your number and bank account are ready. Most of these lean on identity verification, so sort that out first and the rest fall into place. Explore more setup guides in our Phone & Internet section.
