The “history” is not very accurate either.

I can only tell you why I upvoted it: It looks like a useful learning tool, as different sense experiences are associated with each other. I don't find it poorly built, and I don't know enough Japanese to know what's incomplete.

I can name 3 apps that do this website better and actually teach you to write kanji.

- Skritter - Kana (free) - Japanese!

The parent comment is reasonable. Learning hiragana also takes no more than a week or two if you’re actively practicing writing.

Even F-droid has half a dozen apps to learn the writting system.

The problem with learning this, is that when you know katakana and hiragana perfectly, you are still in the same learning spot that you are today to learn finnish or euskera, and much worse than german or danish (they have things in common with english).

Agreed - but probably the tight coupling between the hiragana, the romanji and the audio may give people a bit of a casual revelation about Japanese symbols.

(They are not all anki, wanikani, flavor of the month SRS spammers like some of us)

Because HN is full of weebs and otakus!
