Kana Challenge
How Kana Challenge works
Kana Challenge is a hiragana and katakana app for complete beginners. It teaches both scripts in 30 days with a daily lesson, a quiz, stroke-order writing and a timed game. This page explains each part and how the course decides what you see again.

The 30-day plan
Each day brings five new characters. You finish a lesson by reaching 50 correct answers in its quiz, and days 7, 14, 21 and 30 are review days. You do not plan anything: the home screen shows today's lesson, your streak and what comes next.
| Days | What you learn |
|---|---|
| 1 to 7 | Hiragana foundations: the five vowels, then the K, S, T, N and H columns. Review on day 7. |
| 8 to 14 | Hiragana complete: the M, Y, R and W columns, voiced sounds, P sounds and combinations. Full review on day 14. |
| 15 to 21 | Katakana begins: the same sounds in new shapes, vowels through the H column. Review on day 21. |
| 22 to 30 | Mastery and speed: the remaining katakana, voiced sounds and combinations, speed drills, speaking and a final review. |
What day 1, day 10 and day 30 look like
- Day 1: the five vowels, あいうえお. You watch each one drawn, hear it, take the quiz until you reach 50 correct, and say a few words aloud.
- Day 10: week two, where the M, Y, R and W columns, voiced sounds such as が, P sounds and combinations finish off hiragana. The day still has the same shape: five new characters, the quiz, the words.
- Day 30: the final review of both scripts, after a last week of speed drills. By then you have met all 46 hiragana and 46 katakana, the voiced sounds and the combinations, and more than 130 everyday words.
Each day ends with speaking practice: you say the day's words, and the app shows a percent match and what it heard you say, with a breakdown by syllable. There are two voices, male and female, with an 80% speed option.
Already know some kana? A test-out quiz of 50 correct answers starts you at the first character you cannot read, and all earlier days count as done. No ad plays before the test.
Quiz modes
Every lesson ends with a quiz that runs until you reach 50 correct answers. The characters you miss come back more often, so the quiz spends its time on your weak spots.
- Standard questions: a prompt and a set of answer choices.
- Audio first: hear the kana and pick the character.
- Speed drills in the final week.
- Test-out: the same 50-correct quiz, used to skip ahead.
To try the idea without installing anything, the free kana quiz in your browser asks 20 questions a round and lists your misses at the end.


Write mode and stroke grading
Open any character on the kana charts and choose one of three tabs:
- Watch: the animated stroke order, with the start of each stroke numbered, and Replay, Step and Slow controls.
- Trace (beta): follow a faint guide with a red start dot. Each stroke is graded when you lift your finger: backwards, too short or off the line, the app says so. After three misses on one stroke it shows the correct stroke.
- Write: draw the character from memory. Each stroke is marked right, wrong order or wrong, and the app tells look-alikes such as シ and ツ apart. You get a score and a Great, Good or Try again verdict.
Offline, Watch stays free while Trace and Write need the ad-free upgrade. For every hiragana row animated on one page, see hiragana stroke order, row by row. Stroke data comes from KanjiVG (CC BY-SA 3.0).


Tower of Terror (beta)
The Tower of Terror is a timed writing game. It unlocks once you have tried Day 1 and is still marked beta.
- Two towers, hiragana and katakana, each with four worlds of 10 levels: 80 levels in all.
- Each level asks 20 questions, 10 new kana and 10 review. You see the sound and write the kana before the timer runs out.
- You have 3 lives and can earn up to 3 stars. A wrong shape, a missing stroke or a timeout costs a life; a wrong stroke order still passes.
- A guardian ends each world, and speed levels shorten the timer. After a miss, the correct stroke order plays before the next question.


How review is scheduled
Kana Challenge reviews in three places, each one tied to what you have already met:
- Inside each quiz: characters you answer wrongly come back more often until you reach 50 correct.
- Review days: days 7, 14, 21 and 30 replace new characters with a review of everything so far.
- In the Tower: half of every level, 10 of the 20 questions, is review of kana from earlier levels.
Your streak and optional reminders bring you back the next day. Reminders are offered after your first day, not at launch.

Kana Challenge questions
How long does Kana Challenge take?
The course is a 30-day plan: five new characters a day, a quiz of 50 correct answers to finish each lesson, and review days on days 7, 14, 21 and 30. It covers all 46 hiragana and 46 katakana plus voiced sounds and combinations.
Can I skip the days I already know?
Yes. A test-out quiz of 50 correct answers lets you start at a later day, beginning at the first character you cannot read. All earlier days count as done, and no ad plays before the test.
Does Kana Challenge check my handwriting?
Yes. In Trace (beta) each stroke is graded the moment you lift your finger, and you are told if it is backwards, too short or off the line. In Write mode you draw the whole character from memory and each stroke is marked right, wrong order or wrong.
When does the Tower of Terror unlock?
The Tower of Terror, the timed writing game, unlocks once you have tried Day 1. It has a hiragana tower and a katakana tower with 40 levels each, and it is still marked beta.
Does Kana Challenge work offline?
The free version runs online with ads. The one-time ad-free purchase adds full offline access to the lessons and charts. Offline, Watch stays free, while Trace and Write need ad-free.
