Four essentials: Naver Map or KakaoMap (navigation — Google Maps barely works), Papago (the best Korean translator), Kakao T (taxis), and Korail Talk (KTX train tickets). All have English interfaces and are free.
Nice extras: KakaoMap reviews for restaurants, a delivery app if you have a local number, and our own AI Guide for instant Korea answers.
🙋 People also ask
How do I pay inside these Korea travel apps without a Korean bank account?
Most foreign Visa and Mastercard now work directly in Kakao T and Korail Talk, so you can pay for taxis and KTX tickets with your home card. For top-ups, a Korean phone number helps, but Naver Map, KakaoMap and Papago are free and need no payment at all.
Do I need a Korean SIM or eSIM for these apps to work?
Yes, you need data: a tourist eSIM or SIM (around ₩27,500 for 5 days unlimited) or pocket WiFi lets the maps, Papago, and Kakao T run anywhere. Most apps also require a working internet connection to verify and update routes in real time.
Which Korea apps work offline if I lose signal?
Naver Map and KakaoMap cache recent areas but need data for live transit and routing, so download key directions in advance. Papago offers offline Korean-English translation packs once installed, while Kakao T and Korail Talk require an active connection to book taxis or trains.
