Korea runs on apps, but not the ones you already have. Google Maps is crippled here, your food delivery habit mostly won't transfer, and the two things that actually matter — maps and a translator — take about five minutes to set up before you fly. Here's what works for a visitor, and what quietly requires being a resident.
Maps: install a Korean one before you arrive
Google Maps does not do turn-by-turn driving navigation in South Korea, because detailed map data can't be exported to servers outside the country. Public transit directions work. Walking directions are patchy and often just wrong about which side of a block an entrance is on. Do not plan your trip around it.
Naver Map (NAVER Corp.) is the default recommendation. The app ships in English, Japanese, Korean and Simplified Chinese, and its English mode is the more complete of the two big Korean map apps — more place names actually render in English, and the transit, bus-arrival and place-detail screens hold up. It also has the deepest business data: opening hours, whether a restaurant is temporarily closed, photos of the actual storefront.
KakaoMap (Kakao Corp.) lists English and Korean. It's excellent, and some people prefer its routing and its Road View street-level imagery, but its English layer is thinner — you'll hit Korean-only place names more often. It's a strong second app rather than your only one.
Practical verdict: install Naver Map first. Add KakaoMap if you want a second opinion on routing or you're using Road View to recognize an entrance.
The trick that fixes both: searching in English frequently returns nothing even when the place exists. Copy the Korean name (from a blog, a reservation, or Papago) and paste it into the search bar. Korean text in, correct pin out, every time.
Papago: still the one for Korean
Papago is Naver's translator, covering 14 languages with text, camera/image translation, voice, conversation mode, handwriting, offline text, and website and document translation. It remains widely regarded as the stronger option specifically for Korean — it's a Korean product trained with Korean as a first-class language, not an afterthought.
Google Translate has closed much of the gap and is fine for signs. But Papago's camera translation over a Korean-only menu is the thing you will use constantly, and it handles Korean sentence structure and honorifics more naturally in conversation mode. Carry both if you like; lead with Papago.
Download the offline Korean pack before you leave. Subway basements and mountain temples are where you need it and where the signal dies.
KakaoTalk: the messaging layer
KakaoTalk is not optional if you're interacting with any Korean business directly. Guesthouse hosts, tour operators, hiking guides, small shops and private drivers all communicate through it rather than email or SMS. It's free, it signs up fine with a foreign phone number, and setting it up before you arrive saves an awkward conversation later. That's genuinely all most visitors need it for.
Kakao T: taxis, with caveats
Kakao T (Kakao Mobility) is how Korea hails taxis — it's the dominant app, and it lists English, Japanese and Korean support. For visitors it's usable but not frictionless, and it's worth knowing where it breaks:
- Sign-up with an overseas phone number is possible but inconsistent; some numbers verify immediately, others fail for no visible reason.
- Payment is the real problem. Foreign-issued cards are frequently rejected when you try to register one. This is not fatal — with no card on file, you simply pay the driver directly at the end of the ride by cash or card, exactly like flagging a taxi on the street. Korean taxis take foreign contactless cards in the in-car terminal reliably.
- Communication. Once matched, the flow assumes you and the driver share a language. Have your destination in Korean on screen, ready to show.
A genuine alternative: Uber operates in Seoul as a taxi-hailing service. It's the same taxi fleet in practice, but with an English-first interface and a payment system that already has your foreign card in it. If Kakao T's registration defeats you, this is the fallback rather than a downgrade.
Delivery apps: be realistic — these are for residents
This is where honest advice matters, because plenty of travel content lists Baemin (배달의민족) and Coupang Eats as tourist tips without mentioning that most visitors can't complete a single order.
- Baemin is built around Korean phone verification and domestic payment methods. Restaurant menus are in Korean, addresses are entered in Korean, and the checkout flow assumes a Korean card or a Korean-bank-linked payment service. A short-term visitor typically cannot get through sign-up, let alone checkout.
- Coupang Eats does list English alongside Korean in the app, which sounds promising. But it sits on a Coupang account, which wants Korean phone verification, and foreign-issued cards commonly fail at payment. Some travelers get it working; many don't.
The realistic call: plan not to use delivery. Practical substitutes that require nothing: convenience stores (open 24/7, genuinely good hot food), your accommodation's front desk placing the order for you, and the fact that in any Korean city there's a restaurant within three minutes' walk. Delivery is a convenience you're not losing much by skipping.
The clean dividing line
Works fine for a visitor, no Korean infrastructure needed:
- Naver Map, KakaoMap — no account required at all for basic use
- Papago — no account required
- KakaoTalk — foreign phone number is fine
- Kakao T — usable, paying the driver in-car instead of in-app
- Uber (Seoul) — foreign card, English interface
Effectively requires Korean residency infrastructure (a Korean phone number registered to you, a Korean bank account, or a domestic card):
- Baemin, Coupang Eats and other delivery platforms
- Kakao Pay, Naver Pay and most in-app payment wallets
- Korean banking apps, and some domestic ticketing and reservation platforms that verify identity against a Korean phone number
One last piece of non-app advice: buy a physical T-money transit card at any convenience store and top it up with cash. It works on subways, buses and in most taxis nationwide, it needs no phone number, no bank, and no app — and it sidesteps the entire payment-registration problem in about ninety seconds.
