Best App to Learn Korean: What to Check
By Language Lab editorial team
Best app to learn Korean: seven things to check before you choose, what Korean asks of an app, official material to pair it with and a one-week test.
The best app to learn Korean is the one that teaches Hangeul in the first week and then makes you speak. Korean is a long project for an English speaker: the US State Department places it in Category IV, super-hard languages, and allows 88 weeks, or 2,200 class hours. The alphabet is the easy part: Hangeul has 24 basic letters, combined into syllable blocks. Check seven things before you choose: Hangeul taught first, native audio, spoken practice with a response, self-testing, spaced review, real-life situations, and levels tied to TOPIK, the official test. An app that keeps you in Latin-letter spellings will slow your reading and your pronunciation. Pair it with the free Online King Sejong Institute, and try it for a week before you pay.
What Korean asks of an app
- Hangeul first. It has 24 basic letters, combined into syllable blocks, and it is the foundation for everything else.
- Sound and block together. The app should play each syllable block and ask you to read it aloud.
- Speaking every day. Choose an app that asks you to answer, not only to recognise.
- A named target. TOPIK I gives levels 1 and 2, and TOPIK II gives levels 3 to 6.
Seven things to check
| Check | What to look for |
|---|---|
| Speaking | You say sentences aloud and get a spoken or written response, in situations you will meet. |
| Audio | Recordings by native speakers for every syllable block and sentence. |
| Writing system | Hangeul from the first lesson, with no long reliance on Latin-letter spellings. |
| Self-testing | The app makes you produce the answer before it shows it. |
| Spaced review | Old material comes back after days and weeks, not only in the lesson where you met it. |
| Real situations | Lessons are built on things you will do: meeting people, shopping, travelling, working. |
| Levels | Stages are named, and you can see how they relate to an official scale or exam. |
Why testing and spacing come first
A 2013 review of ten learning techniques, led by John Dunlosky, rated two as high utility: practice testing and distributed practice. Rereading and highlighting were rated low. So an app that makes you produce an answer, and brings items back after a gap, is using your time better than one that lets you tap through and move on.
Test an app in one week
- Day 1: do the first lesson. Did you speak aloud, or only tap?
- Day 2: start a new lesson. Did the app bring back yesterday's material?
- Day 3: check the audio. Is every Korean sentence recorded, and can you replay it?
- Day 4: look for the level map. Can you see where the course ends?
- Day 5: try to say five sentences from memory. If you cannot, the app is not testing you enough.
- Day 7: decide. Keep the app only if you spoke every day.
Pair it with official material
- Online King Sejong Institute: a free online Korean learning service with courses from introductory to advanced.
- Nuri King Sejong Institute: textbooks, learning materials, grammar quizzes and speaking and writing practice.
- Study TOPIK, on the official TOPIK website: past questions and video lectures.
Aim at a level
The official test is TOPIK. TOPIK I gives levels 1 and 2, and TOPIK II gives levels 3 to 6. Choose an app that tells you which TOPIK level each stage prepares you for, and use the official past questions before you sit the test.
A note on our own app
Language Lab is our app, so judge it by the same list. Language Lab's Korean course is built around voiced real-life scenarios with an AI tutor. Use the one-week test above on it as you would on any other.
Frequently asked
What is the best app to learn Korean?
The one that makes you speak Korean aloud, tests you before showing the answer, brings old material back for review and shows you clear levels. Try it for a week before paying.
Is Hangeul hard to learn?
No. Hangeul has 24 basic letters, combined into syllable blocks. A good app teaches it in the first week and then stops using Latin-letter spellings.
How long does it take to learn Korean?
The US State Department places Korean in Category IV and allows 88 weeks, or 2,200 class hours. An app does not shorten that; it helps you use the time well.
Are free Korean apps enough?
Official learning material is a strong start: Online King Sejong Institute is one example. Whatever you use, check that you are speaking and being tested.
What features matter most in a language app?
Practice testing and spaced review, the two techniques a 2013 research review rated as high utility, and spoken practice with a response.
Can an app make me fluent in Korean?
An app can carry your daily practice. You will also need conversation with people and a structured course or exam target for the higher levels.
