Not broken for me but….
The purchases I made did go through and the app did have a way to practice Japanese kanji. However, it’s a great idea and good start to what I was looking for without fulfilling my actual need. It did not have all the kanjis I was looking to practice, and it was difficult to search what they had. I would also appreciate arrows or diagrams instead of YouTube videos for how the kanjis are drawn. Compatibility with the Apple Pencil would be a great improvement as well.
