Ratings and reviews

I like the learning/review section for the hiragana and katakana. I wish the vocabulary section was a bit easier to navigate. I did find where to see and study them first before reviewing them, but it would be nice to have more of a flashcard option or similar review like the hiragana and katakana are. Overall I do think this is a great app for learning.

Great app to learn japanese. It's got all you need to go from complete beginner to N1 knowledge. All of it's features feel polished and all grammar explanations and such are really well structured. It's an app that takes your hand so you can lear japanese in the easiest way possible. And it's constantly growing with cheat sheets, readings, listenings and a lot more features being added

It was very helpful, especially with hiragana and its characters. Sometimes, due to technical problems I believe, it didn't let me do some things. I hope with this review it is looked at. But it was very helpful and I recommend it definitely
