It looks great. I would suggest changing the kanji next to the label "Kanji" to 字 instead of 出, though. 字 is the second character in the word 漢字 (kanji) and means "character." I would also suggest changing the kanji next to the "Vocabulary" label from 言 to 語. 語 is the second character in the word 単語 (tango) and means "word." The あ next to the "Kana" label is perfect.

出 means "to go out or exit" and doesn't have anything to do with learning Kanji. 言 means "to say" and is only tangentially related to learning vocabulary.

Still, great job!

Agreed. PR opened.
