The best apps to learn Korean in 2026

LingoDeer is the best app to learn Korean in 2026 for most beginners: it is a structured course that starts with Hangul, explains grammar inside each lesson and asks you to speak, though full access needs a subscription the developer says starts at $14.99 a month. Duolingo is the best free course if you want a daily habit without paying. Korean is also a language where small single-purpose apps pay off: a Hangul trainer for the first days, Teuida for speaking, and Korean - Lessons+ for free podcast listening.

How to choose: start with Hangul, then pick a main course

Korean has one script, Hangul, and it is compact: 24 basic letters that combine into syllable blocks. That makes the first step much shorter than in Japanese or Chinese, but it is still worth doing properly, because every course on this list moves to Hangul quickly. After that, the real choice is your main course, plus one extra app for the skill you care most about. For broader advice on picking a language app, see our guide to language learning apps.

• For your first week: learn Hangul with Korean! Learn Hangul & Speak if you want writing practice, or with the free Learn Korean Hangul Alphabet if you only want to read. Both are faster than waiting for a general course to reach every letter.
• For a main course with grammar: LingoDeer is the most complete. Duolingo is the free alternative, with less explanation and a stronger focus on streaks.
• If speaking is your goal: add Teuida. Its lessons are built around saying everyday phrases out loud in role-play scenes, with feedback on your pronunciation.
• If you learn best by listening: Korean - Lessons+ collects free Korean podcasts, including Talk to Me in Korean, in one player. It needs a recent iOS version, so check that first.
• If you are preparing for TOPIK or just need more words: Hourly Hangul organizes vocabulary by TOPIK level 1 to 6 and puts words on your Lock Screen.

A practical free setup is the free Hangul drill, then Duolingo, plus Korean - Lessons+ for listening. A practical paid setup is LingoDeer with Teuida for speaking. None of the candidates in our search was a dedicated Korean dictionary app, so this page does not rank one.

LingoDeer: Best overall

LingoDeer is a course app that bills itself as an app for Asian languages, and Korean is the first language in its list. The developer says its lessons are created by language teachers, take about five minutes each, and are customized for languages with their own alphabet, so the Korean course begins with Hangul before moving to words and sentences. Grammar tips appear inside lessons, audio is recorded by native speakers, and Fluent, a set of real-life conversation lessons, is available for Korean. One screenshot shows a speaking exercise for 영화관에 갈까요? ("Shall we go to the cinema together?") with a recording button and a score of 99. Recent updates added more spaced repetition practice modes and explanations of why an answer is wrong.

The listing says a subscription is needed for full access to all courses and features, starting at $14.99 a month. The price list also shows a Multilingual Pass Annual at $95.99 and lifetime passes from $119.99 to $299.99 on the US App Store in November 2026.

Strengths: grammar explained in context, which matters for Korean verb endings and politeness levels. Limits: the listing does not say how much is free; there is no Korean-only plan on the price list; identifiers are used for tracking.

Duolingo: Best free course

Duolingo teaches Korean for free in short, game-like lessons, and the course list in its screenshots includes Korean alongside Japanese and Chinese. The description says every course is free and lists Korean by name. Its streaks, leaderboards and reminders are the main reason to choose it: it is good at getting you to study a little every day. The exercise screenshot, taken from the Japanese course, shows the typical format: hear a word, then tap the matching picture.

Super Duolingo, which the description says removes ads and adds unlimited energy, comes with a 14-day free trial and is listed at prices from $9.99 to $119.99 on the US App Store in November 2026.

Strengths: the only full Korean course here that costs nothing. Limits: the free version has ads and an energy limit; the description does not mention grammar explanations, Hangul writing practice or TOPIK; the privacy label lists tracking across eight data types. Learners who outgrow it can compare options on our Duolingo alternatives page.

Korean! Learn Hangul & Speak: Best for learning Hangul

Korean! is a small, focused app from Luli Languages that teaches you to read and write Korean. The listing describes lessons covering all Korean characters, optional writing lessons, a Show and Quiz method, a personalized review system and audio pronunciation, all without a network connection. The screenshots show the course as numbered levels, starting with vowels and consonants, and a writing exercise where you trace 각 (gak) over a guide, with a Show Hint button and audio playback.

The price list on the US App Store in November 2026 sells content in pieces: Hangul Levels for $2.99, individual later levels at $3.99, Unlock all levels or all lessons at $12.99, and an Unlock Monthly item at $0.99. The listing does not say which levels are free or what the later levels cover beyond the alphabet.

Strengths: handwriting practice on full syllable blocks, not just single letters, and no tracking on the privacy label. Limits: it requires iOS 17.5 or later; it has no speaking feedback; the description is short, so it is hard to tell from the listing how far beyond Hangul it goes.

Teuida: Best for speaking practice

Teuida is built on one idea: you learn to speak by speaking. Each lesson puts you in a first-person scene, such as ordering at a cafe or asking for directions, where a bilingual tutor talks to you on video and you answer out loud. The developer says the app gives instant feedback on your pronunciation through voice recognition and adds culture tips for each scenario. The screenshots show a tutor saying 감사합니다 (thank you) with an "Awesome!" reaction and a large record button. It covers Korean, Japanese, Spanish and French, and is rated 4.9 from about 59,300 ratings.

The listing says you need a TEUIDA Premium plan to access all content. Prices on the US App Store in November 2026 include 1 month at $14.99 or $17.99 and 12 months at $59.99, $79.99 or $89.99.

Strengths: regular speaking practice in realistic situations, without the pressure of talking to a stranger. Limits: most content needs Premium; the listing says little about Hangul or grammar instruction, so it works best next to a course; it is rated 13+ and uses identifiers for tracking.

Korean - Lessons+: Best for podcast listening

Korean - Lessons+ is a hub for learning resources rather than a course. Its center is a player for publicly available Korean podcasts, including Talk to Me in Korean, Choisusu's Easy Korean Podcast and Korean Study Cafe, with material from beginner to advanced. Around that, the app adds a Hangul section with an intro, a reference and a Korean keyboard, Hangul writing practice that traces stroke order with animation, flashcards with spaced repetition, a Word of the Day widget and printable worksheets. The screenshots show the home screen with Word of the Day (평화, peace) and podcast tiles, and a stroke practice screen for the letter ㄱ.

The app is ad-supported. Lessons+ Premium removes ads and allows offline downloads, and is listed at $0.99 and $7.99 on the US App Store in November 2026. It also supports CarPlay, which suits commuters.

Strengths: a lot of free listening material in one place, with no tracking on the privacy label. Limits: it requires iOS 26.1 or later, the strictest requirement on this page; the free version shows ads; it does not give a step-by-step lesson path.

Hourly Hangul: Best for TOPIK vocabulary

Hourly Hangul puts Korean words on your Lock Screen and Home Screen through widgets and scheduled reminders, so you see new vocabulary throughout the day. Each word opens with its Hangul, romanization, meaning, example sentences and audio. The listing also describes Hangul Foundations lessons for reading, writing and building syllables, a placement test, vocabulary from TOPIK levels 1 to 6, personal flashcards with smart review, microphone-based pronunciation feedback, and grammar taught through sentences. The screenshots show a TOPIK 1 card for 사랑 (love), a widget with 기다리다 (to wait), and a feature list that includes Anki import.

There is a 7-day free trial, and the listing says paid access is required after it. Hourly Hangul Pro is listed at $4.99 (30 Days), $7.99 and $34.99 on the US App Store in November 2026. The listing says there are no ads.

Strengths: TOPIK-organized vocabulary that reaches you without opening the app. Limits: not usable for free after the trial; it was released in July 2026 and has only 441 ratings; identifiers and usage data are used for tracking; some content is available only in English.

Learn Korean Hangul Alphabet: Best free Hangul drill

This app from Fast Robo teaches one thing: reading Hangul. It has flashcards for consonants and vowels, quizzes with high scores, a pronunciation soundboard and a short guide that explains how Hangul works. The screenshots show the guide cards ("Letters are grouped into syllable character blocks") and practice sections for starting consonants, vowels and ending consonants, each with a Practice all and a Quiz button.

Everything is free. The only in-app purchases are tips of $1.99, $4.99 and $9.99 on the US App Store in November 2026, and the privacy label says no data is collected. It works offline and was updated in October 2026.

Strengths: the simplest free way to learn to read Hangul, with the cleanest privacy label on this page. Limits: it covers reading only, with no writing practice described; there is no vocabulary or grammar; it has fewer than 1,000 ratings.

What we left out

• Cake. Popular for learning with K-pop and K-drama clips, but its first screenshots all show English lessons, so the listing says little about its Korean content.
• Learn Korean & Study Hangul (Drops). A picture-based vocabulary game; the description says it teaches zero grammar, and it was last updated in December 2024.
• Eggbun. A chatbot-style Korean course, left out because it was last updated in June 2025 and declares tracking of four data types.

Frequently asked questions

What is the best free app to learn Korean?

Duolingo is the best free full course. For the alphabet, Learn Korean Hangul Alphabet is free with only optional tips, and Korean - Lessons+ gives free access to Korean podcasts with ads. Together they cover reading, a daily course and listening without paying.

How do you learn Hangul quickly?

Use a dedicated Hangul app for the first few sessions instead of waiting for a general course to introduce every letter. Hangul has 24 basic letters that combine into syllable blocks, so a focused app can cover all of them. Korean! Learn Hangul & Speak adds handwriting practice; the free Fast Robo app focuses on reading.

Is LingoDeer or Duolingo better for Korean?

LingoDeer explains grammar inside its lessons and has speaking exercises with a score, but needs a subscription for full access. Duolingo is free and better at building a daily routine, but its description does not mention grammar explanations. If you will pay, LingoDeer is the more complete course; if not, start with Duolingo.

Which Korean app corrects your pronunciation?

Teuida's listing says it gives instant pronunciation feedback while you speak in role-play scenes. LingoDeer's screenshots show a speaking exercise that scores your recording, and Hourly Hangul lists microphone-based pronunciation feedback. None of these replaces a human tutor, but they give you regular practice.

Which app helps with TOPIK preparation?

Hourly Hangul is the only app here that organizes its vocabulary by TOPIK level, from 1 to 6, and it offers a placement test. It does not claim to be official TOPIK material, so pair it with a course and practice tests for the reading and listening sections.
