The Kana Monster App is a comprehensive learning tool that helps you to memorize all Hiragana and Katakana characters in an effective way.

Developed by Japanese language linguists, the Kana Monster App follows a well established, card box based approach that enables you to focus on Kana that are difficult to memorize and allows you to constantly repeat the characters that you feel insecure with.

Kana Monster lets you create your own learning set of flash cards from all Hiragana or Katakana characters. While memorizing the cards of your current set, you can file your cards in different boxes: If you are certain that you remember the reading of a Kana, place the card in the ‘Familiar’-box. After a couple of days review the cards in the ‘Familiar’-box and place cards that you still remember into the ‘Mastered’-box. Kana that you want to review go back into your current set of flash cards.

After filing more and more flash cards into the ‘Mastered’-box, you can add new cards to your current learning set.

Using this method of constantly repeating only unconfident Hiragana and Katakana characters, ensures that all Kana gradually move to you long-term memory.


- Create your own individual learning sets from all 214 Hiragana and Katakana characters by using five sets of cards: Unread, Read, Familiar, Mastered and Revision
- Learn new characters by using flash cards that let you show and hide the reading of each Hiragana / Katakana character

App Doesn't Work

The description says that this app works on an iPod Touch, but every time I tried to open it, the app wouldn't open. Don't bother getting it. The developers should have made sure it would open before they put it out.

This app is incredible. Simple and easy, very user friendly- its the whole package! It lets you categorize the kana on what you think your ability is. Very good kana review! I'm going to reccomend this to my friend; (She wants to master katakana)

I also reccomend this to you! 

Missing some characters

I have yet to get to the Katakana, but when studying the Hiragana, there were some characters missing. Not good, if you would like to learn ALL of the kana in Japanese!
