The Best App to Learn Korean: An Honest Comparison

The short answer, by goal

Pick by the job you need done, not by app-store rating.

• Best overall: Talk To Me In Korean. Built only for Korean, with 1,700+ lessons in an order that makes sense.
• Best free: HowToStudyKorean, with Duolingo's free tier alongside it as the habit-builder.
• Best for hangul: HowToStudyKorean's Unit 0, three lessons that get you reading.
• Best for grammar: LingoDeer first, then Talk To Me In Korean when you outgrow it.
• Best for speaking: italki. A human, once a week, starting earlier than feels comfortable.

Why there is no single best app to learn Korean

Korean asks four separate things of a beginner. Read hangul. Learn a grammar that puts the verb last and glues small particles onto every noun. Build vocabulary from almost zero shared words. And pick a politeness level before you can finish a single sentence.

No app does all four. Most do one well, one adequately, and quietly skip the rest. Prices and tiers below were checked against each product's own site in July 2026 and move often, so read them as the shape of the deal rather than a quote.

Two of those are not apps in the usual sense. HowToStudyKorean is a website, and italki books real teachers. Both earn a place because they fix exactly what the apps leave broken.

Numbers are their own small mountain, since Korean runs two complete counting systems side by side. That lesson lives at Korean numbers, and this page stays on apps. If you are still deciding whether to start at all, the hardest languages to learn puts Korean's real hour cost in context.

Hangul takes days, not years

Here is the fact that should change how you shop for a Korean app. Korean does not use thousands of characters. It uses an alphabet, 한글 (hangeul), of 24 basic letters: 14 consonants and 10 vowels. A motivated beginner can learn to read it over a long weekend.

That alphabet was designed rather than inherited. Sejong the Great introduced it around late 1443, and it was promulgated in 1446 in a text called the Hunminjeongeum. The design is why it goes fast. The shapes of five basic consonants are based on the speech organs that produce them, and extra strokes mark related sounds that are harsher. Some scholars call this a featural script, a system where the shapes themselves encode sound features, and others dispute the label. The learner-facing point survives the argument: the letters are not arbitrary, so they stick.

Letters then stack into syllable blocks instead of running in a line. Each block holds an initial consonant, a vowel, and sometimes a final consonant. That is the only genuinely new habit, and it stops feeling strange within an hour.

So treat any app or listicle that frames Korean as years of script memorisation as a bad source. It is confusing Korean with Chinese. HowToStudyKorean puts the whole job in Unit 0, three lessons that the site says give you everything you need to be able to read Korean, for nothing.

That gives you a clean first test for any app: does it get you off romanization fast? An app still showing you annyeonghaseyo in week three is building a habit you will spend months undoing. Duolingo rebuilt its Korean course on 7 July 2026 and now runs alphabet sessions along the path plus a dedicated Hangeul tab, though the same update added transliterations for every sentence, which you should switch off in settings the moment you can read.

The real wall: word order, particles and speech levels

Hangul is the easy part. What stalls people arrives in week two and never fully leaves.

Korean puts the verb last. It is a subject-object-verb language, so an English sentence has to be dismantled and rebuilt rather than swapped word for word. That feels fine on five-word sentences and gets genuinely hard once a sentence has a clause inside it.

Particles do the work English does with word position. Small markers attach to nouns to say what role each one plays, and most have two forms depending on whether the noun ends in a consonant or a vowel.

Choosing between the topic marker and the subject marker is a real grammar problem that native speakers feel rather than recite. No amount of tapping the correct tile teaches it.

Then there are speech levels. Korean grammar has seven of them, and the verb ending encodes how you rank yourself against the person you are talking to. Three matter to a beginner.

Older grammar books call 하십시오체 by its earlier name, 합쇼체. Three of the seven levels are fading out of everyday speech, so a beginner can safely park them.

This is the yardstick for the rest of the page. An app that hands you Korean sentences without saying which level they sit in is teaching you to be accidentally rude, and that is the most common complaint about the gamified apps.

Korean app comparison at a glance

The Korean-first courses: TTMIK, HowToStudyKorean, LingoDeer, Duolingo

Talk To Me In Korean

TTMIK is the closest thing to a default answer. It has taught Korean and only Korean since 2009, its catalogue runs past 1,700 lessons sorted into beginner, intermediate and advanced, and each lesson moves through a warm-up, the teaching, speaking practice and a review quiz. Because Korean teachers built it for Korean, particles and speech levels get taught rather than implied.

It also asks for money soonest. You get one full free lesson, Core Grammar 1, and a 7-day trial on the Standard Plan. After that the site's own pricing starts around $7.12 a month billed annually, with the Standard Plan listed at $10.17 a month billed annually. Their podcast, which splits each episode into beginner, intermediate and advanced segments and runs through the usual podcast apps, is a good way to test the teaching style first.

HowToStudyKorean

For the honest free answer, it is this website, and it is not close. HowToStudyKorean runs nine units from Unit 0 to Unit 8 plus a Hanja section, roughly 25 lessons each, and every lesson carries 20 to 30 vocabulary words with audio recordings of every Korean word and sentence. The site states plainly that its lessons will always be free.

Unit 0 is the hangul course. Units 1 upward are the grammar reference most self-taught learners quietly rely on, and they name the particles instead of hoping you notice them. The catch is presentation: long-form text on a web page, with no streaks, no spaced repetition and nothing to open on the bus. Workbooks and printed books are the paid part.

LingoDeer

LingoDeer is what to reach for if Duolingo left you guessing. It was built around Korean, Japanese and Chinese, and it describes its own curricula as grammar-based, written by language teachers, with detailed explanations, HD audio from native speakers and stories that put the grammar back into dialogue. Its Korean course opens with an alphabet unit.

The trade is cost and ceiling. LingoDeer's own pricing page lists paid plans only: US$14.99 monthly, US$39.99 quarterly and US$95.99 for a year, with multi-year options and a 7-day money-back guarantee on some plans. Treat the free portion as a sample. It also runs out sooner than TTMIK does, so think of it as a strong first year rather than the whole journey.

Duolingo Korean

Duolingo's Korean course has a reputation as one of its weaker ones, and independent reviews are consistent about why: grammar explained thinly or not at all, particles introduced without being named, speech levels mixed together without labelling which is which, and speech recognition that accepts bad pronunciation. In a language where politeness is grammar, that middle problem is not cosmetic.

Duolingo has been moving on it. Explain My Answer, its in-lesson feedback tool, became free for all learners on 1 January 2026. The Korean course was then rebuilt on 7 July 2026, more than ten years after launch, adding alphabet teaching sessions along the path, a dedicated Hangeul tab, what Duolingo calls smarter grammar teaching with new exercise types, and content reaching up to B2.

That is a real answer to the old complaints. It is also eleven days old at the time of writing, so nobody knows yet how well it holds. What has not changed is the pedagogy: Duolingo teaches by pattern rather than by explanation, and particles and speech levels are exactly the material that pattern-spotting handles worst. The free tier now runs on Energy, which Duolingo describes as a battery that powers your learning and refills over about a day, topped up by streaks of correct answers, rewarded ads or gems. Use Duolingo for the habit and get your grammar somewhere else.

The support tools: Anki, Memrise, Drops, italki

Anki

Anki is a flashcard program that, in its own words, helps you spend more time on challenging material and less on what you already know. You rate how well you recalled a card and it schedules the next review for when you are most likely to forget. That matters more for Korean than for Spanish, because English gives you almost no free Korean vocabulary and every word has to be built from scratch.

It is free on Windows, macOS and Linux, and AnkiDroid on Android is free too. The iPhone and iPad app is paid, and those purchases fund the project. The interface looks its age, and it teaches you nothing on its own: you feed it words you met in a lesson, then ten minutes a day. HowToStudyKorean publishes free Anki packages, which removes the worst of the setup.

Memrise

Memrise's pitch is that you learn the language real people speak, using authentic video clips of locals so you hear the speed, slang and emotion, with AI speaking practice on top. That fills a genuine Korean gap, because textbook audio and a Seoul cafe sound like different languages.

You can start learning for free and a paid plan unlocks the extra features. Memrise does not publish prices on the pages we could reach, so check the current plans before subscribing. Treat it as a listening and vocabulary tool wearing a course's clothes. It will not walk you through particles.

Drops

Drops is vocabulary as a five-minute game: illustrated words, spaced repetition and visual association across 55 or more languages, with over 5,000 words and phrases available. Korean is well served, and the illustrations dodge the English-translation crutch.

The free version runs on a session timer, which is why Premium's headline feature is Unlimited Time. Their site lists Premium at $11 a month, $69.99 for a year, or $150 for lifetime access. The real limitation is structural. Drops teaches words, and Korean words without particles and verb endings do not assemble into sentences. Good as a fifth tool, risky as a first one.

italki

italki is a marketplace rather than an app. Korean tutors set their own rates, and listings run from roughly $5 to $70 an hour, with most sitting between $6 and $25. Community tutors are native speakers doing conversation practice; professional teachers hold teaching qualifications and bring materials. Every tutor goes through italki's verification process.

Book one before you feel ready. A speech level is a choice you make in real time under social pressure, and there is no way to rehearse that alone. Thirty minutes a week with a patient teacher does what no amount of tapping can.

The best app to learn Korean for each goal

Best overall: Talk To Me In Korean. One Korean-specific course that carries you from your first sentence to advanced material, taught by people who explain what the general-purpose apps skip. It costs money almost immediately, and it is the least wasted subscription on this page.

Best free app to learn Korean: HowToStudyKorean, with Duolingo for the habit and Anki for retention. Those three cost nothing on desktop and Android, and between them they cover script, grammar, daily practice and memory.

Best for hangul: HowToStudyKorean's Unit 0, three free lessons and done. LingoDeer's alphabet unit and Duolingo's new Hangeul tab both work. The difference is that HowToStudyKorean expects you to finish reading in days and then move on.

Best for grammar: LingoDeer as a beginner, then TTMIK, with HowToStudyKorean as the free reference you keep open in a tab. All three name the particles and label the speech levels.

Best for speaking: italki, and nothing else is close. Among the apps, Memrise's AI speaking practice and TTMIK's per-lesson speaking step are useful rehearsal. Rehearsal is not performance.

Best for vocabulary: Anki, with Drops as the gentler option if flashcards feel like homework. Korean hands an English speaker almost no free words, so the forgetting curve is the whole fight.

So the best Korean learning app is really a shortlist of two or three, chosen by which of the four jobs you are currently failing at.

A 3-app Korean stack that works

One app for structure, one for memory, one for speaking. Everything else is optional.

The free stack: HowToStudyKorean for structure and grammar, Anki for retention, and one italki lesson a month when you can afford it. The paid stack: Talk To Me In Korean for structure, Anki for retention, italki weekly. If you need momentum before rigour: Duolingo for the streak, LingoDeer for grammar, italki from month two.

Five hours a week, spent roughly like this:

Two rules keep it honest. Read hangul only, never romanization, from week two onward. And settle your default speech level early: 해요체 suits almost every learner, polite enough for strangers and normal enough that you will not sound like a news anchor.

Give it eight weeks before changing anything. Korean progress stays invisible for about a month and then arrives in a lump.
