"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

Awesome app!!!

I had already bought Dr Moku’s hiragana app and absolutely loved it. I had been really struggling with memorizing all the different Japanese letters and that app made it so simple to learn and actually remember day to day, month to month. All the silly pictures and sayings make it nearly impossible to forget! I thought that I would try and get by with just the lite version of Dr Moku’s katakana. It took me months of practice before I felt like I knew all the letters pretty well. Then I got busy and didn’t work on any Japanese for a month or so, and when I got back to it, the only Katakana letters I could remember were the ones that I learned from the katakana app. I had no problem remembering all the hiragana and the few katakana letters from the lite app because I could associate them with the pictures and phrases. I was so frustrated and tried to practice writing them over and over hoping it would help. I finally decided to go ahead and get the full version of the app. I hate myself for not doing it sooner- All the unnecessary stress! The app is awesome and just as helpful as the hiragana app. I’m so grateful for the stories that tie in all the similar looking katakana. It just makes learning this alphabet so simple. I can’t recommend both apps enough. Spend the money, it’s well worth it! *Also as a side note, I contacted the app support team with a question and they responded very quickly and were so helpful and friendly. I couldn’t have asked for better service.

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!

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.
