Store description excerpt
Tsubu (粒粒) helps you memorize JLPT Japanese vocabulary — one grain at a time, day after day. A focused, private vocabulary trainer for N5 through N1. No account, no ads, no tracking. Everything runs on your device and works offline. • Spaced repetition that adapts to you. An FSRS-6 memory curve schedules each word right before you'd forget it, so reviews stay efficient as your deck grows. • Six question types, not just flashcards. Words rotate through meaning, reading, kanji, kana, listening, and sentence-context questions, so recall is built from every angle. • Mock exams in the JLPT exam format. A single paper mixes six JLPT-style question types, so you know where you stand before exam day. • Natural pronunciation. Every word and example sentence ships with high-quality, natural audio, with readings locked to the correct furigana — no robotic mispronunciations. • Listen anywhere. A hands-free mode plays through your deck section by section, with lock-screen and background playback. • Stay motivated. Daily goals, streaks, level-up challenges, coins and ranks turn review into a habit — with a countdown to your JLPT exam date. • More than words. Dedicated drills for grammar points (N5–N1), polyphonic kanji, and counters (助数詞). • Easy on the eyes. Soft, low-contrast colors designed for long study sessions, in light and dark themes. • Yours forever. A one-time purchase unlocks everything — no subscription. Your progress stays on your device and can be backed up to a file anytime. Built for learners studying for the JLPT. Interface in English and Simplified Chinese. Dictionary, example, and reading data are gratefully acknowledged in the app (JMdict / Tatoeba / Kuromoji). See About → Data Sources & Licenses.
