Korean · 7 apps compared
There is no single best Korean app, only the best one for the gap you are trying to close. Here is what each of these does well, what it does badly, and what learning Korean actually demands.

Short answer
For Korean specifically, NativePal is the strongest all-round pick: it generates reading at your level, tracks vocabulary with spaced repetition, and scores your pronunciation on individual sounds. Add Anki if words are not sticking, Pimsleur if you want hands-free audio, and italki or HelloTalk when you need a real person to talk to. Duolingo remains the best option if your problem is consistency rather than method.
1. Best all-round practice loop
The only app here that covers levelled reading, vocabulary with spaced repetition, pronunciation scored down to individual sounds, and conversation in one place. Free to start with a daily allowance.
Where it falls short: If you only want one narrow thing — pure audio, or pure flashcards — a specialist below will do that one thing better.
2. Best for building a daily habit
Nothing is better at getting you to open an app every single day. The streak mechanic works, and a habit you keep beats a better method you abandon.
Where it falls short: Gamification can substitute for progress: long streaks often coexist with weak speaking and reading ability.
3. Best for raw vocabulary retention
Free, open source, and the best spaced-repetition scheduling available anywhere. If your problem is that words do not stick, this is the tool.
Where it falls short: It is a flashcard engine, not a course: no lessons, no speaking practice, no curriculum, and you have to build or download decks yourself.
4. Best for lessons with a real teacher
A marketplace of human tutors, which no AI matches for catching the thing you did not know you were doing wrong. A good teacher beats any app, including NativePal.
Where it falls short: You pay per lesson and have to schedule them, so it works best as a weekly anchor rather than daily practice.
5. Best for hands-free audio
A disciplined audio method that makes you speak aloud from the first lesson. Genuinely usable while driving, walking or cooking, which is time most people cannot otherwise study in.
Where it falls short: Very little reading, and the fixed lesson order means you cannot skip ahead to what you actually need.
6. Best for talking to native speakers
Puts you in text and voice contact with actual native speakers, with a genuinely usable free tier. Real conversation with real people, at no cost.
Where it falls short: It is a social app, not a course, and the quality of any exchange depends entirely on who you match with.
7. Best for reading volume
A large comprehensible-input library plus the ability to import your own articles, videos and books, with unknown words tracked as you read.
Where it falls short: The interface is dated and it does very little for pronunciation or structured beginner grammar.
Among the hardest for English speakers, despite an easy alphabet. Hangul was designed to be learnable and most people read it within a few hours to a few days. It is by far the easiest part of Korean.
The US Foreign Service Institute budgets around 2200 hours of instruction — roughly 88 weeks full-time — to reach professional working proficiency in Korean. Whichever app you pick, that is the scale of the commitment for full fluency; conversational ability arrives much sooner.
Korean proficiency is measured with TOPIK, so it is worth choosing an app that pitches material at a level rather than a single generic difficulty.
These are the features that most often stall English speakers, and the ones an app needs to handle well:
For an all-round practice loop — levelled reading, vocabulary with spaced repetition, and pronunciation scored down to individual sounds — NativePal. If you need one specific thing instead, Anki is better for retention, Pimsleur for hands-free audio, italki for lessons with a human teacher, and Duolingo for building a daily habit.
The US Foreign Service Institute puts Korean at roughly 2200 hours of instruction, about 88 weeks full-time, to reach professional working proficiency. Simple conversation comes far sooner, typically within the first few months of consistent daily practice.

Yes, to a point. NativePal is free to start with a daily allowance across reading, vocabulary and speaking practice. Anki is fully free and open source but supplies no lessons. HelloTalk's free tier lets you talk to native Korean speakers at no cost. A free stack works; it just requires you to assemble it.
Read aloud against something that scores you, so you find out which sounds are wrong instead of drilling them in. NativePal's teleprompter grades individual vowels and consonants, stress and rhythm, fluency and connected speech, and its 60-second daily challenge adds freeform speaking. For conversation with a person, italki for paid lessons or HelloTalk for free exchanges.
