iroiro: Japanese Vocab & JLPT Android

Japanese? The real problem is kanji.

You've tried flashcard apps. You've ground through vocaabulary lists. But kanji just won't stick — because you've been memorizing shapes instead of understanding structure.

Every kanji is built from smaller components called radicals. Learn the radicals, and kanji stops being a wall of random strokes. It becomes a system — one you can actually read, remember, and use.

iroiro is a Japanese vocabulary app designed to make kanji click, not just cram.

How it works

We break each kanji into its radicals, then lock the meaning in place with a vivid mnemonic — a short, memorable image that connects the pieces to the whole. Instead of seeing 休 as an arbitrary symbol, you see a person (亻) leaning against a tree (木) to rest. That's not a trick. That's how the character was built.

Do this consistently, and something shifts: unfamiliar kanji starts to look readable. You recognize the parts, guess the meaning, and you're right more often than you'd expect.

What makes iroiro JLPT different

◦ Radical decomposition + mnemonics for every kanji — understand the structure, not just the stroke order
◦ Vocabulary and kanji learned together — double the efficiency in the same study time
◦ FSRS spaced repetition algorithm — review exactly when you need to, skip what you already know
◦ Hiragana & katakana through visual association — master the basics fast
◦ Example sentences + native audio — hear how words actually sound in context
◦ Kanji writing practice — go from recognition to production
◦ Step-by-step JLPT levels (N5 → N1) — a clear path from beginner to advanced
◦ Content reviewed by a former Japanese textbook author
◦ Cross-device sync — pick up where you left off on any device
