"After a half hour, I was blazing through each exercise: highly recommended for beginners". - The Huffington Post

“I came across Dr. Moku's Hiragana Mnemonics....Thirty minutes later I had memorized all hiragana". -

Mnemonics are memory tricks that use humor or a memorable personal connection to help you fix and break associations so your brain has no choice but to remember.

Each screen presents a Katakana character along with a mnemonic clue and audio clip. Read the clue, listen to the clip and move on to the next one. The alternating bold colors will 'reset' your brain so you start fresh with each character. Then take a quiz! You will be amazed at your ability to recall Katakana after just a few minutes.

This free Lite Version covers 25% of Katakana. We offer an in-app purchase which adds the entire mnemonic system, additional quizzes, word search game

Ratings and Reviews



Much more effective than just repetition of the kana over and over again. I put off learning katakana because I already knew hiragana and it took me a while using a different app. I didn't want to spent a long time learning katakana but I learned 13 of them almost instantly! YAYYY

Incredibly awesome!

Ninda nada

This free version contains 13 words to memorize. Now memorizing becomes easier because of this amazing game! I can memorize 13 katakana words in less than 45 minutes!

But the words are too few, if you want more, you have to prepare some dollars to purchase.

Not s good as hiragana


This one isnt as good as the hiragana fre download. Some of the mnemonic styles are not sensible but I was willing to try them over and over. However when I tried to test myself the quiz gave me the majority of unfamiliar katakana on its easiest setting. Therefore I couldn't test the 10 learnt. I would hope they improve these inconsistencies so the app can be enjoyed.
