No app does everything. The honest picks by job: Hanguljo for the Hangul→TOPIK path with SRS and conversation practice, LingoDeer for gamified beginner lessons, Talk To Me In Korean for grammar depth, Naver Dictionary as the dictionary everyone needs, Anki for DIY flashcard power users, italki for speaking. Duolingo? A habit-builder, not a Korean course. Most learners do best with a stack of two or three.
Yes, we make one of these apps — so let’s earn your trust the only way that works: by being specific about what every tool does well, including our competitors, and where each falls short, including us. Korean has distinct sub-skills (Hangul, vocabulary, grammar and particles, listening, speaking), no single app covers them all, and the “best app” question is really a “best stack” question.

Hanguljo — the structured path from zero to TOPIK
Our lane is the whole spine of the journey: guided Hangul foundations (stroke order, letter breakdowns, native audio), then TOPIK 1–6 lessons covering vocabulary, grammar and particles step by step, locked into memory by a 7-stage SRS. The piece most apps skip: conversation practice by TOPIK level — real-life dialogues with play-along audio and shadowing, so you speak out loud from the start. Plus on-device OCR to look up any Korean text with your camera. It’s free, with a calm, distraction-free design.
Where it’s not enough: an app can’t correct your pronunciation in real time or push back in a live conversation — that’s what tutors and partners are for.
LingoDeer — the polished beginner course
Built by Asian-language teachers (unlike Duolingo), with proper grammar notes attached to every lesson and sensible Korean-specific ordering. If you want a gamified hand-hold from zero through lower-intermediate, it’s the best of that genre. Limits: content thins out after the beginner levels, and review depth doesn’t match a dedicated SRS.
Duolingo — the habit machine
Nothing builds a streak like Duolingo, and a streak is worth something. But its Korean course under-explains the two things that make Korean Korean — particles and verb endings — and tile-matching plateaus fast. Use it as a warm-up act if you love it; don’t make it the show.
Talk To Me In Korean — the grammar teacher
TTMIK’s lessons and audio explain Korean grammar more clearly than any textbook — friendly, thorough, and paced for self-learners. It pairs beautifully with an SRS app: TTMIK explains the grammar point, your SRS makes the vocabulary and patterns permanent. Limits: retention is on you; there’s no serious spaced-review system built in.
Naver Dictionary — the dictionary (get it regardless)
The definitive Korean-English dictionary app: rich example sentences, audio, handwriting input. Every Korean learner ends up with it installed. Free.
Anki — maximum control, maximum friction
The power tool of spaced repetition: any card format, decades of proof. The catch: you become your own course designer — finding decks, fixing audio, tuning intervals. If tinkering energizes you, great. If it drains you, use an app with content and scheduling built in (that’s exactly the gap Hanguljo fills).
italki — where speaking actually happens
Apps don’t fix your spoken Korean; humans do. italki connects you with tutors from ~$8–15/hour. Two 30-minute sessions a week from the few-hundred-words stage prevents the classic “can read, can’t speak” trap. Budget alternative: language exchange partners (free, less structured).
The right stack for your level
Recommended combinations
- Complete beginner: Hanguljo (Hangul first, then TOPIK 1 vocabulary) + Naver Dictionary.
- TOPIK 1–2: Hanguljo (SRS + conversation shadowing) + TTMIK for grammar deep-dives + a weekly italki session.
- TOPIK 3 and up: Hanguljo for the long vocabulary climb + K-dramas/podcasts daily + regular tutoring. Apps become support; input becomes the engine.
Start with the part every stack needs
Whatever combination you choose, the structured vocabulary-and-grammar engine is non-negotiable — and that’s Hanguljo: Hangul → TOPIK 6 with native audio, 7-stage SRS, and conversation shadowing. Free, no credit card. (Learning Japanese or Chinese too? Our sister apps Kanjijo and Hanzijo use the same method — one Premium unlocks all three.)
Download Hanguljo — FreeFrequently asked questions
Is Duolingo enough to learn Korean?
No. It builds a habit and some recognition vocabulary, but leaves particles, verb endings and real listening underdeveloped. Treat it as a supplement at most.
What’s the best completely free setup?
Hanguljo (free) + Naver Dictionary + TTMIK’s free lessons + K-content for listening + a language-exchange partner for speaking. Zero dollars, full coverage.
Which app is best for the TOPIK exam specifically?
Hanguljo organizes its entire path by TOPIK level — vocabulary, grammar and conversation practice per level — then add official past papers for format practice in the final weeks.
How is Hanguljo different from LingoDeer?
LingoDeer is a guided beginner course that fades after lower-intermediate. Hanguljo is a system for the whole distance — Hangul through TOPIK 6 — built around SRS retention and spoken shadowing. Many learners use both: LingoDeer for early lessons, Hanguljo to make everything permanent and keep climbing.
