T-Money, Kakao T, Naver Map: The Only 3 Apps You Actually Need in Seoul

Almost every first-time visitor lands with the same three habits: open Google Maps, hail an Uber, and figure the transit card is a transit card. All three assumptions break here, in three different ways, and none of them are obvious until you're standing at a bus stop wondering why your route just... didn't load. Here's what to actually put on your phone before you land. 📱

1. Naver Map — not Google Maps, and there's a real reason why

Google Maps can show you the map itself and basic search results, but its turn-by-turn directions, bus routings, and business listings are unreliable here. This isn't a bug — Korea restricts the export of its detailed map data abroad, a national-security rule tied to the country technically still being at war with the North, and Google has never been allowed to route around it.

Naver Map is the actual fix, not a workaround. It's a Korean app built on Korean map data, and it now runs a full English interface — station names, transfer instructions, and exit numbers all display in English once you switch it in settings. Kakao Map is a reasonable second opinion for restaurant reviews and real-time bus tracking, but Naver Map is the one to install first.

2. T-money — think of it as a card first, an app second

T-money is Seoul's transit card, and for most visitors it's still exactly that: a physical card. Buy one at any convenience store or subway station, then top it up with cash at the blue charging machines in every station — it works on the subway, buses, and plenty of taxis, all with a single tap.

There's now a mobile version, but it's not evenly available yet. iPhone users can add T-money to Apple Wallet and top it up with a foreign Mastercard or Amex (Visa isn't supported for this yet). Android doesn't have an equivalent foreign-card option at the same level — a physical card is still the more reliable route. Unless you're specifically set up with an iPhone and the right card, just buy the physical one; it's cheap, it's everywhere, and it never needs a data connection to work.

3. Kakao T — for calling a taxi, with one thing to know upfront

Kakao T is the default taxi-hailing app here, but the standard version effectively assumes a Korean phone number, which most visitors don't have. Our guide on missed the last train covers the actual foreign-card workarounds (k.ride, UT, Taba) in detail — the short version is: you don't need to give up on hailing a taxi, you just need a different app than the one every local has already installed.

A Note From Daniel — our real human editor

We watch this happen at check-in constantly — a guest pulls up Google Maps to walk to the guesthouse, and it just won't give them a walking route, or sends them somewhere strange. Once we point them to Naver Map instead, it clicks immediately. It's the single most common first-day confusion we see.

Soo's Tip

Set Naver Map's language to English before you land, while you still have wifi or data to do it — station names and settings menus are a lot harder to figure out cold, over an unfamiliar interface, at an airport with spotty signal.
