Apps that work in Korea — the 5 you actually need (and Google Maps isn't one)

Before we get into anything: Google Maps does not give walking or transit directions in Korea. Not because it's broken — because Korean national-security regulations prohibit detailed Korean map data from leaving domestic servers. Google can show you driving routes and that's it. So your first 20 minutes in Seoul will be a confused stare at your phone, unless you download a few local apps before you land.

Here are the five that actually do the work.

1. Naver Map — your daily driver

The most-used Korean map. Now supports four languages: English, Korean, Japanese, Chinese — switch in the app settings on first launch. It handles everything Google Maps does back home: transit routing with live bus and subway arrivals, walking directions, restaurant reviews (with auto-translated menus and reviews), even indoor maps for big underground shopping centers.

If you only download one app, make it this one.

2. KakaoMap — the second opinion

Korea's other major map app. Has an English interface (Settings → Language), with similar transit and restaurant data. Two reasons to keep it alongside Naver Map:

• Real-time visual transit tracking is a bit cleaner than Naver's.
• If Naver Map's search misses something, KakaoMap often catches it (different review databases).

Both apps support English with some variation in interface coverage — some place names may stay in Korean on either app, and for less-touristed spots a Korean-script search sometimes catches more results. For 90% of major destinations, both apps work fine in English.

3. Kakao T — taxis without speaking Korean

Korea's dominant taxi-hailing app. Works for foreign visitors without a Korean phone number via the "Guest Mode" / Skip-login option. You enter your destination (English place names or hotel names work), select "Pay to Driver Directly", and pay the driver on arrival — cash, international credit card (Visa / Mastercard / AMEX), or T-money card.

If you want the full account with saved payment, you can register an international credit card (number + expiry + CVV + billing address) and verify with a small authorization charge.

This is the main fallback when subways stop running around midnight.

4. Papago — the translator

Naver's translation app. Better than Google Translate for Korean specifically — sharper on menus, slang, signs. The camera mode lets you point your phone at Korean text (a restaurant menu, a sign, a label) and read the English translation overlaid in real time. Voice translation works for back-and-forth conversation. Supports a long list of languages including English, Japanese, Chinese, Vietnamese, Thai.

Pair it with Naver Map and you can read any menu in any restaurant.

5. WOWPASS — the all-in-one payment card

A prepaid card built for foreign visitors. One card does two jobs:

• Pay anywhere in Korea — malls, cafes, restaurants, convenience stores, hospitals. Issued in Korea, so it's accepted where international credit cards sometimes aren't.
• Public transport via T-money — top up the T-money function (KRW cash only, at subway machines or convenience stores) and use it on subway, bus, and taxis.

You can pick up the card at Incheon Airport T1 / T2 CU convenience stores (24/7) or any WOWPASS machine. Top up using 15 foreign currencies (cash) or overseas credit cards through the WOWPASS app. The exchange rate is usually better than the airport counters, and there are no foreign-transaction fees.

The honest take

Five apps, all free, none of them takes more than 5 minutes to set up. Together they replace Google Maps + Uber + Google Translate + an international credit card combined — and they work better than that combo does in Korea. Download them on the plane. You'll be a working version of yourself the moment you land.
