Exactly what I was looking for!

I didn’t have high expectations as I was not having any success with other Japanese Learning Apps but I tested out Koji and it was exactly what I needed. Then I got the premium and it unlocked everything else!

Very good app

Been using this on my commute every morning. Lessons are short enough that I can finish one before my stop and the quizzes mix things up enough that it never feels repetitive. Almost done with katakana.

Best way to learn Japanese!

Honestly didn't think I'd stick with this but I'm on day 11 and still going. The memory tricks for hiragana are what got me — I actually remember them without having to look anything up anymore. Way better than what I tried before.

Highly Recommend!

My boyfriend is Japanese and I've been trying to surprise him by learning to read his texts. Started with zero knowledge and already recognize most hiragana after 10 days. The native speaker audio is really helpful for getting the pronunciation right.
