You already know you want to pass TOPIK. The real question is how — without burning study time on words that won't move your score, or losing a week to reviews you didn't need. TOPIK Note sorts 9,000+ Korean words by exact TOPIK level and schedules your reviews for you, so every minute goes to the words that count. Study what matters, when it matters. The app remembers what you know and what you don't. SM-2 spaced repetition (8-stage intervals) tracks every answer and adjusts your schedule automatically. Hard words come back sooner. Words you've nailed space out further — so you're never drilling something you already own. FOUR WAYS TO LEARN EACH WORD • See the Korean word, pick the meaning • See the meaning, pick the Korean word • Fill in the missing word in a sentence • Read a Korean sentence and choose what it means Same word, four angles. By the time it sticks, you can use it in context — not just spot it on a flashcard. With 36,000+ quizzes, you won't run out. HEAR EVERY WORD Tap the speaker on any word or example sentence to hear how it's pronounced. Reading Korean is half the work — knowing how it sounds is the other half. MADE BY KOREANS, REVIEWED BY KOREANS Every definition and example is written and checked by native Koreans — no clumsy machine translations to unlearn later. EVERY TOPIK LEVEL, ONE APP • Beginner (Level 1–2) — foundational words • Intermediate (Level 3–4) — everyday and compound words • Advanced (Level 5–6) — academic and nuanced vocabulary Pick your level. Switch anytime. The app adapts to your pace. GRAMMAR BUILT ON WORDS YOU ALREADY KNOW 210 TOPIK grammar points — from beginner particles to advanced connectives (79 beginner, 94 intermediate, 37 advanced). Every example sentence is built from vocabulary you've already studied, so a grammar point arrives as a sentence you can actually say, not a rule to memorize. • Fill-in-the-blank, conjugation, and meaning quizzes for every point • Spot a grammar pattern inside any word's example sentence and tap straight through to its explanation • Reviews are scheduled the same way as vocabulary — the grammar you keep missing comes back sooner PRACTICE REAL TOPIK EXAMS Vocabulary gets you ready. Past exams tell you if you're ready. • 1,700+ real TOPIK I & II questions pulled from 21 past exam papers — 878 reading and 850 listening • Listening questions play the original exam audio. Answer first, then read the full transcript to see exactly what you missed • Submit your answer, then read an explanation that walks you through the correct choice — available in English, Japanese, Vietnamese, and Chinese (Simplified and Traditional) • "My answered questions" keeps everything you've tried, sorted by wrong and right, so you can drill your weak spots • Exam stats: overall accuracy, separate TOPIK I and II progress, a 30-day trend, and a breakdown by question type TRACK YOUR PROGRESS A stats dashboard that earns its space: • Daily study streak • Accuracy across each quiz type and TOPIK level • Wrong Notes — every word you miss, collected automatically so you can target your weak spots No vanity metrics. Just signals for where to focus next. STUDY ON YOUR TERMS Bookmark words you want to revisit. Set a daily reminder — even five minutes a day compounds over weeks. YOUR LANGUAGE, YOUR INTERFACE App interface in English, Japanese, Vietnamese, and Chinese (Simplified and Traditional). Word definitions in all of those plus Korean. The Korean stays Korean — only the explanations change. You've decided to learn Korean. TOPIK Note makes sure your time goes to the right words, in the right order.
