Ratings and Reviews


Very Useful

This app has been extremely useful in my studies of Japanese, and I would definitely recommend it for any serious (intermediate) Japanese learner.



Edit: updated to reflect that the developer addressed the bugs I pointed out.

The dictionary algorithm works well and is fast. The UX design of the app is not that great, hence 4 stars not 5.

Developer Response

One star is a bit harsh, isn't it?
Anyway, those issues have been corrected in the latest release version 2.5.0.


Good but lacking

I really enjoy this app so far, especially the aozora bunker e-reader features. That alone has helped me tremendously in reading more Japanese texts.
However, I would just like to clarify somethings that I feel weren't apparent to me at the time of purchase. The app has 3 features accessible from its main menu; a browser, an e-reader connected to aozora bunko, and study lists. The standalone browser can access websites and use its features like define and add to wordlist. But it doesn't integrate with safari as well as I would like it to. Maybe this is a difficulty created from Apple's end. In safari, you can only define a word and not add it to a wordlist. As a matter of fact, that's the only thing you can do outside of the app itself. Maybe this is only important to me, but I prefer to keep these vocabulary words to review later. I'm finding it a critical default, that I can't add to wordlist outside of the app. If I want to do that, I have to copy the URL from safari, paste it into wakaru's browser, highlight the word, and then add it to a wordlist. It would be great to have the add to wordlist functionality available everywhere, ie safari and mail.
In any case, I look forward to this app and it's improvements.
