What Duolingo's Korean course actually includes
Duolingo describes itself as a free app for quick lessons in more than 40 languages. Its exercises cover speaking, reading, listening and writing, with Korean among the named courses.
The Korean course received a substantial update in July 2026. Duolingo says the course now teaches through B2. That label doesn't guarantee speaking ability, though: several reviewers with 1,000-plus-day streaks said they still couldn't hold a simple conversation.
The updated path includes clearer grammar goals and several Hangeul lessons spread along the learning path. The Korean writing system also has its own tab, so alphabet practice isn't restricted to ordinary lessons.
Every Korean sentence can display a transliteration. You can switch these hints on or off through the gear symbol during a lesson.
Duolingo reports more than 1.9 million current Korean learners, and the course is now available from 27 base languages. That means a friend learning from Portuguese or Japanese can use the same course as you.
Duolingo's main format remains short translation, recognition and multiple-choice exercises. For example, you might recognise a Korean word in a sentence without producing that sentence during a conversation.
Where Duolingo is good for Korean
Duolingo's strongest use is building a regular study habit. Its short lessons make it easy to practise a few Korean words during a spare part of the day.
The course provides repeated exposure to Korean sentences, vocabulary and written forms. This can help a beginner become more comfortable seeing words such as 커피 and identifying familiar sentence patterns.
The app is also fun for many learners. Positive App Store reviews repeatedly describe it as easy to use daily, useful alongside school classes and helpful for basic words.
Every course is free, although free use comes with Energy and advertising. That gives beginners a way to sample Korean without immediately buying a subscription.
The app holds a 4.7 rating from 5.4 million US App Store ratings. Version 7.139.0 was released on 8 September 2026.
The limitation is depth. Recognition exercises can tell you that you've seen a word, but they don't prove you can retrieve it while speaking.
That distinction appears often in recent reviews. Several people with streaks exceeding 1,000 days said they still couldn't manage a simple conversation.
The Hangeul problem
Duolingo teaches Hangeul gradually inside its Korean course, usually through vocabulary and alphabet sessions spread along the path. It doesn't begin with one concise explanation of the complete system.
The July 2026 update added several Hangeul lessons along the path. That is an improvement, but learners still meet letters gradually instead of seeing a concise explanation of the complete system first.
This matters because similar sounds need focused comparison. For example, 가, 카 and 까 represent a plain, aspirated and tense contrast that benefits from direct speaking practice.
Vocabulary can create another practical test. 커피 means coffee, while 코피 means nosebleed, so a vowel difference changes the word.
Consonant contrasts also deserve deliberate work. 불 means fire, 풀 means grass and 뿔 means horn, but Duolingo doesn't rate your pronunciation of the individual letters.
Lingrow's iOS Hangeul course takes a more systematic approach. It covers all 40 letters across nine lessons, including 14 basic consonants and five double consonants.
It also teaches 10 basic vowels, 11 compound vowels, syllable blocks and batchim. A placement test lets learners skip letters they already know.
Every letter has Korean audio, and the app rates pronunciation at the letter and syllable level. Its 가, 카, 까 drill asks you to say all three, then checks whether they sound different.
The course also checks handwriting from memory using recognition. A spaced repetition grid tracks strength separately across all 40 letters.
As far as we can find, no other Hangeul app rates pronunciation at the individual-letter level. You can compare more options in our guide to the best apps to learn Hangeul.
For free reference material, use the interactive Hangeul chart. The written Hangeul guide explains the system outside a lesson path.
Audio and pronunciation
Duolingo's Korean audio is robotic and doesn't sound like natural Korean. Recent reviews also report unclear voices and unnatural accents in some language courses.
Speech exercises can provide a small amount of spoken practice. However, reviewers report correct pronunciation going unrecognised and speaking exercises freezing.
More importantly, Duolingo doesn't rate the pronunciation of individual Korean letters or sounds. It cannot show whether your 가, 카 and 까 are sufficiently distinct.
It also doesn't provide a pronunciation report after each conversation. There is no detailed summary showing which vowels, consonants or words need further work.
Lingrow gives real-time feedback while you speak in a roleplay. After the conversation, it provides a summary covering grammar, vocabulary, fluency and pronunciation.
The Hangeul course adds narrower sound checks. For example, it rates vowels and the difference between plain and aspirated consonants at the individual-letter level.
That makes Lingrow the stronger choice when pronunciation is your main concern. Duolingo remains useful for hearing and recognising words, but recognition isn't the same as checked production.
Speaking practice: what you get free, with Super and with Max
Free Duolingo mainly uses short lesson exercises rather than open Korean conversations. Speaking practice is minimal, with much of the course built around translation and multiple-choice tasks.
The free version now uses Energy instead of Hearts. Each lesson consumes some Energy, correct answers build some back, and a full recharge takes about one day.
When Energy runs out, you can watch a rewarded advertisement or buy a refill with gems. Recent reviewers frequently say they only complete a couple of lessons before stopping, sometimes during a lesson.
Super removes those Energy limits and advertisements. It also adds skills practice, mistakes review and monthly streak repair, but it doesn't turn Korean into a full conversation course.
Max adds Roleplay and Video Call with Lily in supported courses. Roleplay provides conversation practice with Duolingo characters and feedback on response accuracy and complexity.
However, Roleplay isn't available for English speakers learning Korean. Its listed languages include French, Spanish, German, Portuguese and Italian.
Korean access to Video Call is less clear. Duolingo's help centre doesn't list Korean, but a Duolingo blog says iOS learners can use Video Call in Korean and Japanese.
During Video Call, Lily responds in real time and remembers previous discussions for later calls. Recent reviews complain that learners cannot sample this feature before paying for Max.
Max only works in Duolingo's iOS and Android apps, and it cannot be purchased on the web. Duolingo's help centre says some AI features aren't available across all courses, and the Korean Roleplay gap is one example.
Lingrow offers voice roleplays across more than 350 real-life scenarios, from ordering coffee and taking the metro to dating and job interviews. Korean is its most developed language.
The difficulty adjusts while you speak, and feedback appears in real time. Each conversation then ends with specific advice across pronunciation, fluency, vocabulary and grammar.

Grammar
Grammar explanations are virtually nonexistent in Duolingo. This becomes a problem with Korean word order, particles and honorifics.
The July 2026 course update introduced clearer grammar goals. That improves lesson organisation, but it doesn't provide the same teaching depth as a tutor-led explanation.
Recent reviews reflect this gap. Some learners say the app rewards passive recognition and handles grammar and writing systems poorly, even after long streaks.
Lingrow includes more than 100 guided lessons. An interactive whiteboard teaches words, phrases and grammar, while the tutor takes questions during the lesson.
Each guided lesson ends with a short roleplay using the material you just studied. That links a grammar explanation directly to spoken use rather than another recognition question.
Lingrow also includes flashcards with spaced repetition. You can save words from conversations or use curated decks ranging from 100 common words to exam-level vocabulary.
What Duolingo costs for Korean
Duolingo's Korean course can be used for free. The trade-off is advertising and the Energy system, which can interrupt how many lessons you complete.
Super costs around $13 a month or around $84 a year as of September 2026. The US App Store lists several annual and family entries, so the exact option shown can differ.
Duolingo's App Store listing advertises a 14-day Super trial. Its Super webpage advertises a one-week trial.
Super includes unlimited Energy, mistakes review, skills practice and no advertisements. Its family option covers up to six Super accounts.
Max costs more than Super. Duolingo shows the price inside the app, and it varies by region.
A Max family subscription can be shared with five other users. Before paying, remember that Korean has no Roleplay and uncertain Video Call availability outside the iOS blog announcement.
Gem packs range from $0.99 to $19.99 in the US App Store purchase list. Free learners can use gems for Energy refills when a lesson drains their remaining balance.
Recent reviews often describe the paid plans as expensive. Check the current in-app offer before subscribing.
Lingrow is an iOS subscription with a free trial. You're paying for guided lessons, pronunciation checks and conversations rather than an unlimited version of short exercises.
What to use instead, weakness by weakness
For structured alphabet study, use Lingrow's nine-lesson Hangeul course. It teaches all 40 letters, syllable blocks and batchim, and tracks each letter in a spaced repetition strength grid.
For a free alphabet reference, use the interactive chart and written guide linked above. They let you examine Hangeul as a complete system instead of waiting for each letter along a path.
For pronunciation, use Lingrow's individual letter and syllable ratings. The 가, 카, 까 sequence provides a concrete three-way consonant contrast that Duolingo doesn't score.
For broader speaking, use Lingrow. Its 350-plus scenarios include coffee orders, metro journeys, friendly chats, dating, travel and workplace situations.
For grammar, use Lingrow's guided lessons before entering a roleplay. The tutor explains words, phrases and grammar on a whiteboard, then lets you ask questions.
For conversations with real people, use a free language exchange such as HelloTalk. It connects you with native speakers, although no software checks your pronunciation.
These choices don't require deleting Duolingo. You can keep its daily vocabulary routine, then add the specific tool that covers each missing skill.
Our best apps to learn Korean compares options across these needs. If you're unsure where to begin, take the free Korean level test, which gives you a TOPIK estimate in three minutes.
Who should keep using Duolingo for Korean
Keep using Duolingo if short lessons help you study every day. It works well for basic words, repeated sentence exposure and a free starting point.
It can also support another Korean course. For example, use Duolingo for daily recognition, then use Lingrow's guided lessons and their short end-of-lesson roleplays for speaking.
Don't rely on it alone if conversation is your main goal. The clearest warning comes from reviewers with 1,000-plus-day streaks who said they still couldn't hold a simple conversation.
It is also a weak primary choice for systematic Hangeul study. The separate writing tab helps, but it doesn't rate letters such as 가, 카 and 까.
The fair verdict is to keep Duolingo for habit and exposure. Add Lingrow for structured Hangeul, guided grammar, pronunciation assessment and feedback during actual Korean conversations.
Frequently asked questions
Is Duolingo good for learning Korean?
Duolingo is good for building a daily habit and meeting basic Korean words and sentences. Its updated course reaches B2 on paper. However, its Hangeul teaching, grammar explanations, pronunciation support and speaking practice are limited. Lingrow is a better fit when you want guided Korean lessons and conversations with detailed feedback.
Does Duolingo teach Hangeul well?
Duolingo teaches Hangeul gradually through alphabet sessions and vocabulary along its learning path. It also has a separate writing system tab. However, it doesn't present the complete system first or rate individual letters. Lingrow teaches all 40 letters across nine lessons, then checks handwriting and pronunciation.
Can you become fluent in Korean with Duolingo?
Duolingo alone is unlikely to prepare you for comfortable Korean conversation. Several reviewers with streaks beyond 1,000 days said they still couldn't hold a simple conversation. Use Duolingo for regular exposure, Lingrow for guided speaking with feedback, and a language exchange such as HelloTalk for conversations with native speakers.
Does Duolingo Max work for Korean?
Duolingo Max has limited Korean support. Roleplay isn't available for Korean. Duolingo's help centre doesn't list Korean for Video Call, although a Duolingo blog says iOS learners can access it. Max costs more than Super, its price varies by region, and Duolingo only shows the price inside the app.
What should I use instead of Duolingo for Korean?
Use Lingrow for structured Hangeul lessons, guided grammar teaching and Korean roleplays with real-time feedback. Its Hangeul course rates individual letters and syllables. HelloTalk is useful when you want a free exchange with native speakers, although no software checks your pronunciation. You can also use Lingrow's free Hangeul chart and written guide.
