TOPIK Vocabulary App Review: 4,700+ Korean Words in 47 Categories with Flashcards and Spaced Repetition
Whether you are preparing for TOPIK I or TOPIK II, or learning Korean for travel, work or following your favorite artists, vocabulary is the foundation everything else rests on. A good TOPIK vocabulary app makes the difference between words you memorize for a day and words you actually keep. Long word lists and paper notebooks tend to feel tedious, and most of what you cram fades within a week.
In this review, ChatStick takes a close look at “TOPIK Vocabulary: ศัพท์เกาหลี”, a new education app released on the App Store on September 27, 2026. It was designed specifically for Thai-speaking learners, so every word comes with its meaning in Thai. If you study Korean through Thai, live in Thailand, or are bilingual in Thai and English, this is the audience the app was built for.
What Is TOPIK Vocabulary?
The app’s promise is simple: learn Korean words that stick, a few minutes a day. It bundles more than 4,700 practical Korean words organized into 47 categories. The home screen shows your daily goal, your streak and shortcuts into flashcards, quizzes and review. Because the built-in scheduler decides which words you should see next, your only job is to open the app and put in a few minutes each day.
4,700+ Words, 47 Categories and 4 Learning Paths
Instead of one giant dictionary, the vocabulary is split into learning paths so you always know where to start.
Beginner: greetings, numbers, days and dates
TOPIK I: core vocabulary for the beginner-level exam
TOPIK II: intermediate to advanced topics such as society, economy, business and Korean idioms
Practical Korean: travel, restaurants, hotels and office Korean
Each word card is detailed. You get the Hangul spelling, romanization, the Thai meaning, part of speech, TOPIK level, Hanja where it applies, and an example sentence with a translation. Seeing the word inside a sentence helps you understand how it is actually used, not just what it translates to.
Flashcards Backed by Spaced Repetition
Flashcards are the heart of the app, and they work with simple taps and swipes. A typical session looks like this:
Pick a mode: Korean to Thai, Thai to Korean, random, saved words, missed words, or by TOPIK level.
Tap the card to flip it and reveal the meaning.
Swipe right if you knew it, swipe left to see it again.
Rate your recall as Again, Hard, Good or Easy so the scheduler can time the next review.
Behind the scenes, a spaced repetition system schedules reviews automatically. Words you are unsure of come back more often, while words you know well are spaced further apart. Every word carries a clear status, moving from New to Learning to Familiar to Mastered, and the app gathers your missed, difficult and favorite words in one place for focused review.
Seven Quiz Types to Test Real Recall

Review of missed questions
You can choose 5, 10 or 20 questions per round, which fits a commute or a short break. Wrong answers are not wasted: the app automatically saves those words for later review. The listening and sentence-based formats also push you closer to the kind of recall the exam actually asks for.
Daily Goals and Progress Tracking
Daily goal: 5, 10, 20 or 30 words per day
Streak with a flower pot: the flower slowly blooms as you keep studying
Detailed stats: 7-day chart, study calendar, TOPIK I and II progress, and accuracy
Motivation: earn XP and achievement badges
Native Audio and Instant Search
Every word has Korean pronunciation audio, with a slow playback option that helps you separate similar-sounding syllables. Search accepts Hangul, romanization or the Thai meaning, so when you hear a word in a drama or a song, you can look it up right away without switching apps.
Study tip: start with a goal of 10 words a day. Do the flashcards first, then finish with a 5-question listen-and-choose quiz, so you train meaning, spelling and listening in one session. After a steady week, raise the goal to 20.
