Best App to Learn Korean Alphabet: Hangul Apps Compared

The best app to learn Korean alphabet is the one that covers all 40 letters with clear audio, builds syllables and lets you practise reading, and options differ mainly in writing practice and audio quality. This page compares five kinds of Hangul app and this site's own lessons on six checks, and it gives each a drawback. It also gives a test you can run on any app in ten minutes and a three-day plan for learning the alphabet.

Key facts

• Hangul has 40 letters: 19 consonants (14 basic and 5 double) and 21 vowels (10 basic and 11 compound).
• Writing practice is optional, because the main goal is reading.
• Final consonants (batchim) are the part most apps teach last, so check them.
• This page uses no ratings, scores or affiliate links.

Best App to Learn Korean Alphabet: the Essentials

Choose by how you like to learn, because Hangul apps fall into three styles. Some are built around sound drills: you hear a letter or syllable and pick the match. Some are built around reading games: you read short words and sentences. Some are built around writing: you trace strokes in the right order. Most learners need the first two, and many do not need the third.

The box shows our editorial picks. They are judgements based on the checks below, not scores.

Our top picks

Each pick has a drawback, given below. A Hangul app is a convenience, not a requirement. If you prefer a page to an app, the Korean alphabet lessons on this site teach the same letters with audio.

A quick check of what "all 40 letters" means helps you test an app. The 14 basic consonants are ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅊ, ㅋ, ㅌ, ㅍ and ㅎ. The 5 double consonants are ㄲ, ㄸ, ㅃ, ㅆ and ㅉ. The 10 basic vowels are ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ and ㅣ. The 11 compound vowels are ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ and ㅢ. An app that skips the double consonants or the compound vowels has not taught the whole alphabet.

How Did We Choose?

We compared each option on six checks, listed from the most important to the least. The page does not run hands-on tests and gives no scores. It compares what each publisher says in its public description and what is widely known about the app, and it asks you to check the store listing for current details.

1. Coverage of all 40 letters and batchim. Does it teach the double consonants, the compound vowels and the final consonants?
2. Audio. Is there audio for every letter and syllable, ideally with a slower version? Is it recorded or generated by text-to-speech? A good app says which.
3. Minimal-pair drills. Does it train you to hear differences, such as ㅓ against ㅗ?
4. Syllable-building practice. Does it show how a block is built, such as 가 from ㄱ and ㅏ, and let you build your own?
5. Writing input. Can you trace or draw letters with stroke order? This one is optional.
6. Offline use and cost. Does it work without a connection, and what is free?

Spaced review of the letters is a bonus. An app that brings back the letters you got wrong at growing intervals saves you from making your own cards.

1. Duolingo: Best for a Guided Start with Reading Drills

Duolingo is the best guided start, because its Korean course begins with the alphabet and moves straight to simple words. Specs: course app; free with ads and limits; paid plan available.

The alphabet lessons use short sound-matching and reading exercises, so you hear a letter or syllable and choose it, then read small words. The free tier is enough to start. Limits and ads change, so check them in the app.

The drawback is depth. The lessons give few explanations of how a sound is made, and they may not stay on final consonants long enough to make them automatic. Writing practice is limited.

Choose it if you want a gentle guided start with a daily habit. Skip it if you want a full explanation of every sound.

2. LingoDeer: Best for Explanations of How Sounds Work

LingoDeer is the best choice if you want notes that say how a sound or a spelling rule works. Specs: course app; some free lessons; a subscription unlocks the rest.

LingoDeer was built for Asian languages, and its Korean lessons start with the alphabet and carry short explanatory notes. Notes of this kind help with rules such as why a plain consonant like ㄱ sounds softer between vowels, as in 아가. According to its store listing, the alphabet lesson and the first unit are free.

The drawback is the paywall: the free part is a sample, so you will need a subscription to go beyond the alphabet and the first unit. Check what the free lessons include before you start.

Choose it if you like notes with the drills. Skip it if you need a fully free route.

3. Memrise: Best for Hearing Different Voices Say the Sounds

Memrise is the best for ear training, because its courses use short clips of different speakers. Specs: course and vocabulary app; part of the content is free; a paid plan unlocks more.

Hearing several voices helps you ignore differences in pitch and speed and focus on the sound itself. Seeing a speaker's mouth on video can help with sounds that English lacks, such as the unrounded ㅓ and ㅡ. Most of the video library is part of the paid plan, so check what the free part includes.

The drawback is that Memrise centres on words and phrases, so its alphabet teaching may be short, and it gives little on writing.

Choose it if you want varied voices from the start. Skip it if you want a step-by-step alphabet course.

4. Drops: Best for Short Visual Recall Sessions

Drops is the best for a few minutes of quick recall, because sessions are short and picture-based. Specs: vocabulary game; a limited free session each day; a paid plan removes the limit.

Its Korean store listing says it covers Hangul, but content can change, so check in the app. The free plan gives about five minutes a day, according to the same listing. The short sessions fit a commute and train fast recognition of shapes.

The drawback is the daily limit on the free plan and a lack of explanation. Drops is a drill, not a course, and it will not tell you why a letter sounds as it does.

Choose it if you want a light, quick routine. Skip it if you need explanations or writing.

5. Dedicated Hangul Apps: Best for Stroke Order and Handwriting

Dedicated Hangul apps are the best category if you want to trace letters in the correct stroke order. Specs: single-purpose apps in the app stores; many are free with ads or a one-time purchase; quality varies.

Many small apps focus only on the alphabet and offer tracing, flashcards and quizzes. This page does not name a single app, because quality and availability change, and an unfamiliar app can be out of date. To judge one, check the date of its last update, read the recent reviews and run the ten-minute test below.

The drawback is quality. Some skip the double consonants, the compound vowels or the final consonants, some use romanization as the main label, and some are full of ads. Others have no audio.

Choose it if handwriting matters to you. Skip it if an app shows romanization instead of audio for every letter.

6. This Site's Hangul Lessons: Best Complete Free Option

This site's own Hangul lessons are the best complete free option for this page's criteria, but judge them by the same checks, since we wrote them. Specs: web lessons and flashcard decks; free; no sign-up.

The Korean alphabet hub covers all 40 letters, the final consonants and syllable building, with audio and practice. For review, the Hangul flashcards give you the letters as cards. The lessons are written in plain English, with each rule followed by an example.

The drawback is that it is not an app. There are no push reminders and no streak counter, and you must open the page yourself. Writing practice is by hand on paper, not by tracing on a screen.

Choose it if you want full coverage at no cost and can set your own reminder. Skip it if you need an app that nudges you every day.

Which App Has the Best Audio?

Audio quality is the first thing to test, because a wrong sound learned early lasts. Judge audio on three points: clear syllables with no background noise, a slower version for new letters and a note on whether it is recorded or generated. Apps that use several recorded voices, such as Memrise, help the ear most. Course apps such as Duolingo and LingoDeer give consistent audio for every item. Text-to-speech can be clear but can make small errors in pitch and rhythm, so use it for the sound of a letter, then compare with a recorded voice for words.

Try the check on the sounds that confuse English speakers. ㅓ (eo) and ㅗ (o) are different vowels: ㅓ is unrounded, with relaxed lips, and ㅗ is rounded. An app should play both and let you pick which you heard.

Which App Has the Best Writing Practice?

For writing, a dedicated Hangul app or a paper notebook beats a general course app. A tracing app shows stroke order and checks your shape. A notebook costs nothing and builds memory well. Do you need to write by hand? For reading, no. For remembering the shapes, a few minutes of handwriting a day helps many learners, because moving the hand fixes the shape of ㅂ against ㅍ and ㅈ against ㅊ. If you choose handwriting, write each letter 5 to 10 times in the first lesson, and then move on to writing syllables and words.

Do Apps Teach Batchim?

Batchim (받침, "support") are the final consonants at the bottom of a syllable. They are the part of the alphabet that apps most often teach last or too briefly. Seven final sounds exist in speech: [ㄱ], [ㄴ], [ㄷ], [ㄹ], [ㅁ], [ㅂ] and [ㅇ], even though many more letters can appear at the bottom. For example, 밖 is written with ㄲ but sounds [박], 부엌 is written with ㅋ but sounds [부억], 낮 is written with ㅈ but sounds [낟], and 꽃 is written with ㅊ but sounds [꼳].

Use the table to test an app on batchim. A "yes" on all four rows means the app teaches final consonants well.

The table is a test and not a verdict on any one app. Run it in the first lesson that mentions final consonants. If the app does not cover them within the first few lessons, use the batchim lesson on this site.

The Coverage Test: ㅐ and ㅔ, ㅓ and ㅗ

Two pairs separate a careful app from a careless one. The first is ㅐ (ae) and ㅔ (e). The standard pronunciation rules (Article 4) still list them as two vowels, but most Seoul speakers today pronounce them the same, so a good app teaches both spellings and says that the sounds have merged in everyday speech. A careless app tells you that they are clearly different, or ignores the pair. Words like 개 (dog) and 게 (crab) show the spelling difference, but in speech the context tells you which is meant.

The second is ㅓ and ㅗ. These are two distinct sounds, and learners confuse them often. Test the app with 어 (eo) and 오 (o), and with 거 (geo) and 고 (go). If the app plays them and checks that you can tell them apart, it passes.

Do Apps Teach Syllable Building?

Syllable building is the skill that turns letters into reading, so test it on its own. A Hangul syllable is a block with a consonant first, then a vowel, and sometimes a final consonant at the bottom. A vertical vowel such as ㅏ sits to the right of the first consonant, and a horizontal vowel such as ㅗ sits below it. A good app lets you place the pieces and hear the result.

If an app only shows finished syllables and never the pieces, you learn 40 shapes plus hundreds of separate blocks. If it shows the pieces, you can read a block you have never seen. For this reason, a building exercise is worth more than an extra flashcard round. This site's syllable lessons work the same way.

Why Romanization Is a Trap in a Hangul App

Some apps label every letter with Roman letters, so ㅓ becomes "eo" and ㅗ becomes "o". Revised Romanization is a useful aid, and this site uses it in brackets, but it is never the goal. The goal is to read the Hangul itself. A reader who depends on Roman letters keeps translating, and the translation slows reading and hides sounds that English letters do not show. For instance, "eo" has no English equivalent for the vowel ㅓ.

The rule of thumb: Hangul first, romanization second. An app is doing its job if the Hangul is large, the audio is easy to find and the Roman letters are small or optional. If the Roman letters are larger than the Hangul, or you cannot turn them off, choose another app. By the end of the first week, you should be able to cover the romanization and still read the lesson.

What Should You Do after the Alphabet?

Once you can read, the next step is to attach meaning. Learn about 50 common words and the first sentence patterns, and keep reading aloud. Move to a course that explains grammar, and make a small deck for the words you forget. The Korean alphabet hub links to the next lessons, and the best apps to learn Korean for free page compares the apps that carry you from Hangul into vocabulary. A good sign that you have finished the alphabet is that you can read a menu or a street sign slowly without help.

A Ten-Minute Test for Any Hangul App

Run this test on any app before you commit. It takes 10 minutes.

1. Minutes 1 to 3: count. Open the lesson list. Does it cover vowels, consonants, double consonants, compound vowels and final consonants?
2. Minutes 4 to 6: listen. Play five letters. Is each clear, and can you slow it down?
3. Minutes 7 to 10: read. Do the first reading exercise. Does it ask you to read a syllable or word, or does it only show romanization? If romanization carries the exercise, the app teaches you to read English letters, not Hangul.

A Three-Day Hangul Sprint

An app, a site or a notebook can all run this plan. It uses about 45 minutes a day, in three blocks of 15 minutes, so the total is 2 hours 15 minutes over three days (3 days × 45 minutes).

Reading will still be slow after three days. That is normal. Many learners can read slowly after a week or two of short daily practice, and speed comes with reading real words every day. Keep a short list of the letters you confuse, such as ㅂ and ㅍ, and review it each day. For the review, use a deck from the Hangul flashcards.

Which Should You Pick?

Match your situation to a pick.

• You want a guided start with a daily habit. Use Duolingo, and add this site's final-consonant lesson if the batchim practice feels short.
• You like to know why. Try the free lessons of LingoDeer, or read the lessons on this site.
• You learn best by listening. Try Memrise, and listen for the voices.
• You want to practise handwriting. Use a dedicated tracing app or a notebook.
• You want everything free in one place. Use the lessons on this site and the flashcard decks. For other free options, see the best apps to learn Korean for free.

Frequently Asked Questions

How long does Hangul take with an app? Most learners can recognise the letters in a few days and read slowly after a week or two of short daily practice. The three-day plan on this page teaches all 40 letters in about 2 hours 15 minutes, but reading speed takes longer. Count a week to read with ease and longer for final consonants to feel automatic.

Do apps teach batchim? Some do, and some teach them late or briefly. Use the batchim check on this page: the app should teach the seven final sounds, show that several letters share one final sound (밖 [박], 부엌 [부억]) and ask you to read words that end in consonants. If an app does not, use a lesson on final consonants.

Should I write by hand? Reading is the main goal, so handwriting is optional. A few minutes of writing a day helps many learners remember the shapes, especially similar pairs such as ㅂ and ㅍ or ㅈ and ㅊ. If you write, trace each letter 5 to 10 times in the first lesson and then move on to syllables and words.

Is there a free Hangul app? Yes. Several apps offer free Hangul lessons, often with ads or limits, and the Hangul lessons and flashcard decks on this site are free with no sign-up. Because apps change, run the ten-minute test before you invest time in one.

Can I learn Hangul in one day with an app? You can learn the shapes of most letters in a day, but you cannot read fluently after one day. Final consonants and the sound changes between syllables need more time. A realistic plan is three short days to learn all 40 letters, then a week of reading practice.
