Must-Download Apps Before Traveling to South Korea

When people ask me how to make a trip to South Korea smoother, my first answer is always: download the right apps before you go. Trust me, it’ll save you so much stress.

Korea has its own set of apps that are insanely good once you know how to use them. I’ve rounded up the ones I recommend to anyone visiting—whether you’re here for a week or a month.

1. Naver Map (네이버 지도)

Forget Google Maps—it won’t get you far in South Korea. Because of government data rules, Google can’t provide full walking routes or subway details here. That’s why locals use Naver Map.

This app is packed with detail, right down to which subway exit to take—super handy in stations with 12+ exits.

• Real-time subway + bus schedules

• Accurate walking directions + subway entrances & exits

• Reliable directions to restaurants & cafés

One of my favorite features is you can save places into a list and pin them on the map. I had all my must-visit cafés, restaurants, and sights marked, which made it so easy to plan optimized walking routes. All of my recs in this guide include a Naver Map link so you can add them straight to your favorites.

Naver also makes transit stress-free. It shows real-time bus arrivals, clear subway exit instructions, and even walking routes inside massive stations. Plus, it lists business hours and flags when a restaurant has a mid-day break.

2. KakaoMap (카카오맵)

KakaoMap is another solid option, and some people actually prefer it over Naver. The interface feels a bit cleaner, and the reviews can sometimes be more detailed and reliable. Even among locals, it’s a toss-up—half swear by Kakao, half stick with Naver—so it really comes down to preference.

Personally, I lean toward Naver Map because it has Papago translation built right in, which makes reading reviews for restaurants or attractions so much easier. The one catch: Naver doesn’t show a star rating system, so you can’t always tell at a glance if reviews are glowing or negative. Kakao does, which is nice if you like quick visual cues.

At the end of the day, both apps are excellent for navigating Korea. Download both and see which one feels more intuitive for you.

3. Papago (파파고)

When it comes to navigating language barriers in Korea, Papago is the app you’ll use the most. Google Translate might cover more languages overall, but Papago is built by Naver (the same company behind Naver Map) and it’s optimized for Korean → English. That means the translations are way more accurate and natural, especially for menus, signs, and casual everyday phrases.

One of the best features is image translation. Just snap a photo of a menu, street sign, or even a full page of text, and Papago instantly translates it for you. I used this constantly for things like Baemin (food delivery) and Coupang (online shopping), which are completely in Korean. It’s also super handy when cafés or restaurants only have menus in Korean—saves you from ordering mystery dishes (unless you’re into surprises).

Some menus get really specific with cuts of meat, regional dishes, or technical cooking terms that even locals might not know. With Papago, a quick photo clears up the confusion.

Why you need it:

• More accurate than Google Translate for Korean

• Image translation is perfect for menus, storefronts, and shopping apps

• Works inside other Naver apps for seamless translations

• Lifesaver for KakaoTalk updates from businesses (like delivery notices or booking confirmations)

4. Kakao T (카카오 T)

Public transportation in Korea is amazing—cheap, clean, and insanely efficient. But there are moments when nothing beats a taxi, and that’s where Kakao T comes in. It’s the all-in-one ride-hailing app that locals actually use, and as a traveler, it’s a total lifesaver.

What I love about Kakao T is how flexible it is for foreigners. Even if you don’t have Kakao Pay or a Korean credit card, you can still book rides and just choose “Other Payment” to pay your driver directly. Both cash and card work fine—I always just tapped my card at the end, no hassle.

For me, taxis were most useful in three scenarios:

• With luggage: dragging suitcases through subway stations with multiple staircases

• Late nights: subways stop running around midnight, so Kakao T becomes essential if you’re out late.

• Day trips gone long: one night, I stayed out way too late in a neighboring city and was relieved that Kakao T drivers were open to intercity rides back to Seoul.

Another pleasant surprise: taxis in Korea are relatively affordable compared to many other countries. Even for longer distances, the fares felt reasonable, and the app made it simple to book without the awkward “taxi roulette” of hailing on the street.

If you’re traveling with big luggage, shopping bags, or just want to squeeze the most out of your day (without worrying about missing the last train), download Kakao T before you land.

5. Catchtable (캐치테이블)

South Korea’s food scene is next-level, but many of the most popular restaurants either require reservations or have long wait times. Use Catchtable to reserve restaurants and bar reservations or grab a queue number before you even show up.

The feature I love the most is remote queuing. Instead of standing around outside a packed spot, you can claim your place in line with a few taps, then explore the neighborhood until it’s almost your turn. On one trip, I knew Haebangchon Chicken (해방촌닭)—a cult-favorite spot in Haebangchon—would be slammed. Using Catchtable, I joined the line early and walked straight in when my number was called.

⚠️ sometimes the global version of Catchtable doesn’t list every restaurant (even if you search in Korean). In that case, switch to the Korean version of the app—it’s more comprehensive. The global app works most of the time, but having the Korean one as backup is smart if you’re serious about hitting the most popular spots.

6. Kakao Talk (카카오톡)

Kakao Talk is Korea's most popular messaging app. Businesses, restaurants, even apps like Catchtable all use Kakao Talk to send updates, confirmations, and reminders.

Catchtable also syncs with Kakao Talk. So when you grab a queue number or confirm a restaurant reservation, you’ll usually get real-time updates straight in your chat. Just a heads-up: most of these notifications come in Korean. That’s where pairing Kakao Talk with Papago is a lifesaver—copy the message, paste it into Papago.

If you want to book skincare or beauty services, reach out to clinics / businesses using Kakao talk to understand pricing, availability and to book your appointment.

7. Baemin (배달의민족)

If you’re traveling in Korea, download Baemin. Trust me. This app has rescued me more times than I can count—whether it was midnight tteokbokki cravings, fried chicken after a long day, or just being too tired to go out again.

The app’s all in Korean, but don’t let that scare you off. Papago will get you through it. Plus, Baemin works with international numbers, so even if you grabbed a data-only SIM, you can still sign up.

Here’s how to make it painless:

• Set your address first. Enter it in Korean (saves a lot of errors).

• Browse and order. It feels just like Uber Eats or DoorDash—pick what you want, check your cart, pay.

• Translate if needed. Screenshot the steps and run them through Papago.

Once you’ve ordered once or twice, reordering favorites is literally two taps. By my second week, I had my go-to spots queued up and could get food on the way in less than a minute.

For me, Baemin became my go-to after long days when I just wanted comfort food without leaving my Airbnb. It takes a little effort at first if you don’t speak Korean.

Another food delivery option is Yogiyo. It features a wide variety of restaurants, allowing you to order Korean dishes right to your doorstep. The app offers menus, user reviews, and delivery tracking, making it a convenient option for dining in.

8. Coupang (쿠팡)

Think of Coupang as Korea’s version of Amazon—but faster. Their “Rocket Delivery” service is no joke: order something late at night, and there’s a good chance it’ll be at your door the next morning.

A quick heads-up though: you’ll need a Korean phone number to actually place orders, so it’s not as plug-and-play as Baemin.

For me, Coupang came through when friends back home sent me random shopping requests—K-beauty items, snacks, even hangover jellies (which, by the way, were way cheaper here than at convenience stores). Instead of running all over Seoul to track things down, I just ordered them to my Airbnb and they showed up the next day.

It’s also handy if you forgot travel essentials or don’t feel like hunting for a local shop.Coupang saved me time and stress so I could focus on exploring, not errands.

9. T-Locker

If you’re traveling around Seoul and don’t want to drag your suitcase or shopping bags through crowded streets or cafés, you can find a locker or suit case storage using T-Locker. The app has an extensive network of lockers throughout Seoul, particularly in subway stations. It enables you to locate all T Locker locations, check locker availability, and view pricing information.

The app connects directly with Naver Map to show you available lockers in subway stations and nearby storage facilities, so you can stash your bags and explore hands-free.

Lockers come in all sizes—from small (perfect for backpacks) to extra-large (big enough for large suitcases). Prices range from ₩3,100–₩6,100 for 4 hours, depending on size. After that, you’ll pay ₩500–₩1,000 per additional hour.

You can pre-book your locker through the app. As you know, some places in Seoul are full of tourists, and the lockers may not be available if already used. With this app, you can save your locker in advance and tour around Seoul hands-free.

10. Korailtalk

For those planning to travel across South Korea by train, Korailtalk is an essential app. It allows you to check train schedules, book tickets, and manage reservations. The app covers the extensive Korail network, making it easier to explore beyond the major cities. It’s especially useful for booking high-speed KTX trains and planning day trips.

11. BucaCheck App

If you have a transit card and are unsure about its remaining balance, the BucaCheck App is a handy tool. With this app, you can check your balance by simply scanning your transit card. This feature saves you the hassle of finding a top-up machine or risking insufficient funds. The app requires your phone to have NFC capabilities (Near Field Communication) to read the card’s data.
