Amazing!

I’ve been a fan of the creator of this app for the longest time, before the app evolved so much. I knew them from a series of N5 and N4 materials available online entirely for free. I studied alone for some years, and it’s in great part thanks to this material that I passed on both N5 and N4 (back in 2021 and 2022). Now, I am very happy to see how the app is much more polished, with lots more resources, as I’m sure it will help me a lot with N3 and beyond. This is a creator I am very happy to support, and I have been very satisfied with everything I have seen so far. I highly recommend it for anyone who’s serious about studying Japanese! The app has a friendly interface and plenty of examples. The VS functionality to help identify differences in similar grammar points is especially useful. Keep up the excellent work! ⭐️

Thank you so much for such a warm and thoughtful review. As an independent developer working on this app by myself, messages like yours truly mean a lot to me. Knowing that you have been using the app since its early days, and that my materials helped you pass both N5 and N4, makes me incredibly happy and grateful. Your support gives me a lot of motivation to keep improving the app and to continue adding useful features, tools, and content little by little. There are still many things I would like to improve to make studying Japanese even more useful and enjoyable. If you ever have any suggestions or requests, please feel free to contact me anytime through the app. Feedback from long-time users like you is especially valuable to me. As a Japanese person, I’m also very happy to know that you enjoy learning Japanese. Thank you again for supporting my work for so many years, and I hope you continue to enjoy your Japanese learning journey!

Finally!

The best app hands down for learning Japanese! So thankful with the amount of other apps I’ve used, dr Moku, Anki, kana, this is by far the best app I’m super thrilled with my experience!

This app has everything

I recently abandoned a well-known language app for this one, and my wife and I have been really pleased with what this one has to offer. It has a nice, intuitive flow with daily reviews, podcasts, books, and language tests. It has everything that I wanted in a Japanese language app.

I love this app… but

The new update makes it very laggy when scrolling up to the top selector for selecting what you want to study (ie grammar, vocab, kanji). It makes the site slightly annoying to use. Overall though, I love the content in the new update, the only thing stopping me from getting the premium upgrade is the lagging (You can still learn up to JLPT 3 for free.) it’s still a very good source to use, it has just become slightly annoying.

フィードバックありがとうございます、コアカアイさん。 Thank you very much for your feedback and for your kind words about the new content! Thanks to reports from users like you, I was able to identify the cause of the lag when scrolling to the study selector. The issue has already been fixed and is now available in version 4.2.1. I apologize for the inconvenience, and I truly appreciate you taking the time to report it. Feedback like yours helps me improve the app for everyone. Thank you again for your support, and I hope you enjoy the latest update!

Incroyable

Cette appli est vraiment génial, que ce soit la qualité de son interface, au contenu des cours/ leçons proposés, tout est top. La version gratuite offre un panel de démarrage dans l’apprentissage cent fois plus qualitatif que bon nombre d’autre appli entièrement payantes !
Honnêtement c’est un 10/10.
