I am in my first year of Japanese(日本語) at university. And I hates carrying all my flashcards for katakana and hiragana. But this app I do not need flashcards anymore! Its the best 8 dollars I have ever spent! Now I agree with another reviewer that there should be a kanji version but untill then I have kanji flip.
