Hey Folks,
I was pointed here by Ben on Hacker News. I made a free mobile Kanji app in 2021 using KanjiVG and it was a joy to work with.
I also made a companion app for hiragana and katakana since it was just a matter of swapping in some data.
Kana Book is available on iOS and Android.
There's a brief write up of how I wrote an SVG parser and render on my project site
here.
Thanks,
-BJ
