★☆☆☆☆Mad as hll12/7/2024
Worse than handmade flashcards

Flashcards are popular, but these have no explanations at all for what they are. On top of that it says its a kanji learning app and the intro lessons are filled with made up names for japanese characters with wrong pronunciations for them. ハ is not fins, カ is not power. On the back side of number kanji the pronunciation is wildly incorrect, google translate is more correct than their answers.
