App Description

Learn hiragana & katakana in 30 days. 250+ words, native audio, speaking renshuu

Learn Hiragana and Katakana. All 96 Characters. 30 Days.

Kana Challenge teaches you every hiragana and katakana character — not by showing you charts and hoping they stick, but by drilling each one until you answer 50 questions correctly per lesson. By Day 14 you know all hiragana. By Day 21 you know all katakana. That is not a promise; it is the structure of the program.

More Than the Alphabet: Your Japanese Foundation

Most kana apps stop at recognition. Kana Challenge does not. In 30 structured days you also build:
• 250+ daily-use vocabulary words, learned in kana (no romaji)
• A trained ear from dual male and female native speaker audio
• Correct pronunciation muscle memory through native audio shadowing with real-time accuracy scoring
• Reading reflexes through speed quiz mode

On Day 31 you move on. To immersion, to kanji, to JLPT prep — whatever is next. This app gets you there, then gets out of your way.

Why Kana Challenge Works When Others Don't

Romaji Weaned, Not Avoided. Kana Challenge shows romaji at the start — then removes it as quickly as possible. You build real character recognition fast, without the confusion of being thrown in cold. By the end of Week 1, most learners no longer need it.

The 50-Correct Rule. Each daily lesson requires 50 correct answers before you advance. Not 5 correct in a row. Not a percentage. 50. That is what builds real muscle memory.

Structured, Not Infinite. 5 characters per day. 15 to 45 minutes. The app tells you exactly what to study and when. You stop wondering what to do next.

Your 30-Day Path
Week 1: Hiragana foundations — vowels and the first columns
Week 2: Complete hiragana including voiced sounds and combinations
Week 3: Full katakana — same sounds, new angular shapes
Week 4: Mixed-script reading, speed drills, and JLPT N5 vocabulary

Everything in the App

Speed Quiz Mode to build reading reflexes under time pressure
Full hiragana and katakana charts — all 96 characters, always accessible
