Dictation closes that gap: every word you miss is one your ear skipped. It trains listening, vocabulary and spelling at once, and it's a focused warm-up for the listening part of exams like DELE, DELF, JLPT, TOPIK, HSK and IELTS. ▸ ATOMIC LEARNING PRO • Unlimited Hard Mode challenges • Replay every past challenge • Unlimited translations and retries • Unlimited review replays • One Pro unlocks all languages • Always ad-free Start small.
