What Apps Do You Need for Traveling in Korea? Maps, Transit, Translation & Payment

Your phone’s home screen might be the single most useful thing you pack for Korea.
Between mapping a subway transfer, splitting a taxi fare, and reading a restaurant menu, the right apps do more work than any guidebook.
This list sorts them by what you’ll actually use each one for, so you know exactly what to download before you land.

What Apps Do You Actually Need for Traveling in Korea?

Six categories cover a smooth trip. A map app for navigation. A transit app or card for subways and buses. A translation app for menus and signs. A payment app for tapping in without a Korean bank account. A reservation app for popular restaurants. And a government safety app for emergency alerts.

You don’t need dozens of apps. Most travelers get by comfortably with five or six installed before departure. Google Maps barely works for walking or driving directions inside Korea, so a local map app isn’t optional the way it might be elsewhere.

Once you’ve sorted out your visa or K-ETA for entry and picked a SIM card, eSIM, or WiFi egg to get connected, apps are really the next layer of trip prep: the tools that make each day easier once you’re actually on the ground. See our Korea entry guide if you haven’t confirmed your visa or K-ETA status yet.

• Navigation: Naver Map
• Transit: Kakao Metro (or Naver Map’s built-in transit routes) + Mobile T-money + Let’s Korail
• Translation: Papago
• Payment: WOWPASS
• Restaurant reservations: Catchtable
• Emergency & safety: Emergency Ready app

Which Apps Help You Get Around Korea? (Maps & Transit)

For getting around Korea, Naver Map is your primary navigation app and Mobile T-money is your transit payment method, with Let’s Korail added if you’re taking KTX or intercity trains.

Inside Korea, Google Maps has no walking directions, no driving directions, and no full transit routing. National mapping data restrictions are the reason.

So locals and long-term residents default to Naver Map. It covers walking, cycling, driving and public transit, plus real-time bus and subway arrival times, business hours, and reviews.

For paying the fare itself, Mobile T-money turns your phone into a tap-to-pay transit card. It works on subways, buses and many taxis. Top-ups now take international credit cards, so no convenience store run is needed.

If you’re heading beyond the city on KTX, SRT, or a regional express train, Let’s Korail handles ticket booking directly from your phone.

Naver Map

• Korea’s most widely used map app, built specifically for local streets, addresses, and transit data
• Walking, cycling, driving, and public transit route options in one search
• Business hours, reviews, and bookmarking so you can save spots before your trip
• Available in English: switch the display language in the app’s settings menu

Getting Around by Subway and Bus

Naver Map’s built-in transit routing already covers most subway and bus trips, showing you exact platforms, transfer walking distances, and next-departure times.

Kakao Metro is subway-only. Some travelers prefer its cleaner line diagrams and transfer visuals, which earn their keep in transfer-heavy stations.

Either app works. Pick whichever interface clicks for you, or lean on Naver Map’s transit tab and skip installing a second app.

Mobile T-money

• Turns your smartphone into a tap-to-pay transit card for subways, buses, and many taxis
• Accepts international credit cards for top-ups, so you don’t need a Korean bank account or cash
• Works alongside a physical T-money card if you’d rather keep a plastic backup

Two newer options are worth knowing about too: Seoul is building tap-to-pay support for foreign credit cards directly (see our Seoul EMV open-loop guide for the timeline), and Busan buses already accept QR payment straight from apps like Alipay and WeChat Pay (see our Busan Zero Pay guide).

Let’s Korail

• Official app for booking KTX, SRT, and other intercity/tourist train tickets
• Supports the Korail Pass, a discounted multi-day rail pass built for international travelers
• Lets you pull up your e-ticket on your phone instead of printing anything

Which Translation App Should You Use in Korea?

Papago is the translation app to use in Korea. It’s built by Naver specifically for Korean and consistently outperforms general-purpose translation apps on Korean grammar, menus, and signage.

Papago handles typed text, photos of menus or signs, handwriting, and voice input across 14 languages, and its camera translation mode is genuinely useful for restaurant menus that only exist in Korean.

Download it before your trip and test the camera-translate feature once. Day one, mid-restaurant, is a bad time to learn the interface.

It handles common phrases offline too, provided you grab the offline language pack in advance. That matters if you’re relying on a prepaid SIM with limited data.

Which Payment App Should You Use in Korea?

WOWPASS is the payment app most international travelers use in Korea. It’s an all-in-one prepaid card built specifically for visitors, combining a transit card and a debit-style card you can use almost anywhere that accepts local payment.

You load money onto it using foreign cash or a foreign card at WOWPASS kiosks found in subway stations and tourist areas, and it can be topped up again at convenience stores once you’re set up.

Because a large share of small vendors, markets, and even some taxis in Korea still don’t accept foreign-issued credit cards smoothly, having a Korean-linked prepaid card removes a surprising amount of daily friction.

It’s not the only option (some travelers get by on a no-foreign-transaction-fee credit card alone), but WOWPASS is the closest thing to a universal local payment method built for tourists. See our currency exchange and payment methods guide for how it compares to cash, cards, and ATM withdrawals.

How Do You Book a Restaurant Table in Korea?

Catchtable is the app to book a restaurant table in Korea. It covers everything from high-end dining rooms to popular casual spots, and lets you see real-time wait times and read customer reviews before you commit.

Many of Seoul’s most in-demand restaurants take reservations only through Catchtable. Others fill so fast that walking in means a long wait or no seat, especially at weekends.

The app shows open time slots directly, so you book ahead instead of guessing whether a place will have room when you arrive.

If you’re more interested in delivery than dine-in, say you’re staying somewhere without easy restaurant access, Shuttle Delivery covers food, and even some clothing and cosmetics delivery, in Seoul, Pyeongtaek, Daegu, and Busan.

Which Apps Keep You Safe in an Emergency in Korea?

For safety, Emergency Ready is the official app to have. The Korean government builds it, and it runs in 21 languages.

Emergency Ready covers disaster alerts and points you to nearby shelters, emergency medical centers, police stations and fire stations. There’s basic guidance inside too, like CPR steps, first aid, and how to find a fire extinguisher nearby.

Korea also pushes emergency disaster texts automatically to phones on a Korean mobile network. Heat waves, air quality warnings, earthquakes and the like.

There’s nothing to download. The disaster alert arrives through your carrier the same way an Amber Alert would elsewhere, so if you’re using a local SIM or eSIM you’ll typically start receiving these without doing anything.

For everything else, the 1330 Korea Travel Hotline connects you to a real person in multiple languages.

• Police: 112
• Fire & ambulance: 119
• Korea Travel Hotline (English, Japanese, Chinese, Russian, Vietnamese, Thai, Malay, Indonesian): +82-2-1330

Once you land, you’ll also go through immigration and customs before any of these apps become relevant day-to-day. If you haven’t reviewed how that process works, see our Immigration and Customs guide for the full walkthrough.
