I'm going to add some ability to display things in romaji in the future, so users can start on some of the actual sentences before completing hiragana/katakana. Agree that getting through all the characters before starting anything else is not motivating.
Thanks for that feedback. The drawing system was originally developed for writing kanji, used in my other app Nihongo. Kanji doesn't have the same kind of long strokes that change direction as hiragana, so I could see it not behaving as well for those. I'll see if I can improve it, thanks!
You should check out my other app, Nihongo (https://nihongo-app.com), it has functionality like this, and is one of the reasons I developed it in the first place.
I take DRM free ebooks and copy them into the app one chapter at a time. It automatically creates flashcards for all the words that appeared that I don't already know, and I can filter down to only words that appear at least twice.
Been thinking about adding EPWING dictionary support to Nihongo for a long time, maybe it’s time to make that happen. It seems to be the only way to get good J-J definitions in particular.
