Yuzu Dojo turns JLPT vocabulary into a habit you can actually keep. Study in short flashcard rounds — swipe what you know and flip cards to reveal their meanings. Short enough for a train ride, a queue, a coffee.
WHAT'S INSIDE
• Vocabulary widgets for your Home Screen and Lock Screen, with optional romaji (iOS 17 or later)
• Part-of-speech labels and Plain form for supported vocabulary
• 10,358 JLPT vocabulary words, N5 through N1
• 925 grammar patterns, N5 through N1
• Hiragana and katakana, all 208 characters
• Every JLPT word in context: an example sentence with its English translation
SCHEDULING THAT LEARNS YOU
Yuzu Dojo runs FSRS, a modern spaced-repetition algorithm. It watches how quickly and how confidently you answer, then moves each word to the day you're most likely to need it. You never decide what to review — you just open the app. Two people studying the same deck end up with different days.
BUILT FOR REAL LIFE
• Download a level and study it offline — subway, plane, anywhere
• Tap a word or a sentence to hear it, read by your device's Japanese voice
• Progress syncs across your devices once you're back online
• See the next two weeks of reviews before they arrive, so a heavy day never surprises you
• Mastery by level, measured from your actual answers rather than guessed
QUIET BY DESIGN
No ads. No leaderboards. Nobody to follow and nobody following you. One reminder a day, at an hour you choose — and if you've already studied, that day's reminder is cancelled.
WHAT KEEPS COMING
Your schedule is recalculated after every session, your history stays in sync across devices, and the decks keep being reviewed and expanded. This is a service, not a one-time download.
SUBSCRIPTION
A subscription is required to use this app. It unlocks every level, every deck, offline downloads, and vocabulary widgets (iOS 17 or later). Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is turned off at least 24 hours before the end of the current period. You can manage or cancel it in your Apple Account settings.
