Are you "Gachi" about Kanji? Stop browsing and start retaining. Gachi Kanji is a high-performance Spaced Repetition System (SRS) built for learners who want to move past recognition and master production. No fluff, no "gamey" distractionsβ€”just the high-yield Kanji you actually need to live and work in Japan. THE GACHI METHOD: REPS & TRACING Science proves that muscle memory is the key to long-term retention. Gachi Kanji combines a powerful SRS algorithm with a precision brush-stroke engine. Trace with Intent: Learn correct stroke order with a high-fidelity drawing interface. SRS Logic: Our system tracks every character. If it’s "Active," you’re drilling it. If it’s "Sleeping," your brain is resting. If it’s "Archived," it’s yours forever. High-Yield Only: We focus on the common Kanji used in daily Japanese life and the JLPT. APP FEATURES: JLPT Structured: Study decks organized from N5 to N1. Deep Filtering: Instantly sort by your mastery levelβ€”Active, Sleeping, or Archived. Neumorphic UI: A clean, sophisticated interface designed for long study sessions without eye strain. Offline First: Study on the train, the bus, or the mountains of Mie. No constant connection required. WHY GACHI KANJI? In Japanese, "Gachi" means to be serious, for-real, and intense. We didn't build a game; we built a tool for the Gachizeiβ€”the serious players. Whether you’re aiming for N1 or just trying to read the signs in your neighborhood, Gachi Kanji provides the structured reps you need to make the language stick. Stop forgetting. Start tracing. Get Gachi.

NihonGO Dokusho

Read your way to Japanese fluency. NihonGO Dokusho is a story reader built for intermediate learners: real, natural Japanese β€” and every word, kanji, or grammar point you don't know is one tap from its card. β€”β€” READ β€”β€” Original stories in natural Japanese, written for learners who've finished a beginner course. Turn furigana on or off. Turn per-sentence English on or off. Open a word-by-word breakdown behind any sentence. Three text sizes, plus day and night themes. Every chapter and scene is titled in English, so you always know exactly where you are in the story. β€”β€” TAP β€”β€” Every underlined word is a card, drawn from a library of more than 8,600 vocabulary words, 2,200 kanji and 660 grammar points. In vocabulary mode, tap a word for its meaning, reading, and example sentences β€” which link on to their own cards. Switch to kanji mode to open any character with its stroke order, radicals, and a memory hint. Grammar points open from the sentence breakdown, and a ε½’ button shows a pattern's other forms, from written to casual. Conjugated words resolve to their dictionary form automatically. β€”β€” LISTEN β€”β€” Every sentence and every scene is read aloud in a clear, natural-sounding Japanese voice β€” real recordings that download with each book and play offline, not a robotic device voice. Listening Mode plays hands-free with full controls on your lock screen and Control Center β€” skip, pause, and play from your headphones like a podcast. β€”β€” REMEMBER β€”β€” Every vocabulary word you tap is saved to your study notebook β€” the word, its reading, and its meaning. The notebook shows just the words due for review: clear one you already knew and it spaces out over days; reveal one you'd forgotten and it comes back soon β€” until it's simply known. β€”β€” YOUR LIBRARY β€”β€” A complete original novel β€” 25 chapters across five free parts β€” plus two companion editions of the same story: a plain Japanese edition with no study aids, and a full English translation. Read the study edition first, graduate to the plain Japanese, or check the English when you must. Each book downloads with a single tap and works fully offline. Your reading position, settings, and notebook sync across your devices through your own iCloud. β€”β€” PRIVATE BY DESIGN β€”β€” No ads, no accounts, no tracking, no analytics. Nothing leaves your device except the books you choose to download. Part of the NihonGO family, alongside NihonGO Dominos (the vocabulary game) and NihonGO Manabi (the textbook course) β€” three apps, one shared, frequency-built card library, so what you learn in one is what you meet in the others.
