I like this app, but there is an occasional issue that is quite vexing. When writing some characters, they're almost always marked as being incorrect even if I trace them exactly as depicted. Ultimately, when I get it "correct," the final result can be skewed and distorted. Sometimes, this gets fixed in an update, but then a formerly correctly recognized character breaks. Also, the "retake review quiz" feature never works. It just says that there are no items left to review.

Please install version 6.1.0, the retake feature should be fixed. I'll check again later this year to improve the drawing recognition. Sorry about that. In the new release, you can enjoy brand new tools to learn Japanese counters, and also much improved on/kun readings information for kanji.

I wanted to expand my knowledge of Japanese, and this seemed like a really good option because of the reviews. But it was not at all what I felt it advertised. I thought I'd be able to start at a more advanced level, but it just immediately starts beginner, which is okay if you wanna start there, but it just felt like a waste of my own time. And I couldn't seem to find any instructions on how it works, so I was completely lost. It also took forever to load.

Wow, I wish I'd downloaded this first when I started learning Japanese! All the grammar and syntax and such are laid out where I can easily read them and take a quick quiz, instead of having to listen to someone explain things or watch a video. That really helps me to process at my own pace! Still a little fuzzy about what to do with "points," and a little overwhelmed by the sheer number of things to explore, but overall, I'm impressed!
