This review/feedback is for my first 5 mins in app. Install was fast and easy 5/5 stars App asks if I have any experience (no) and gives me a beginner's guide 5/5 stars First task is learning characters. Starts quizzing me, hasn't told me what characters are. Every answer wrong 0/5 stars. No teaching happened for someone with zero experience, just immediate negative feedback. I'm going to have to find another resource to teach me things, then use the app as a self-test. Not what I expected.

Thank you for trying Sottaku. When learning hiragana, we recommend starting off with small subsets (such as 5 characters at a time), memorizing them, and then expanding the set that you learn. You should be able to learn very quickly with this procedure (the whole alphabet in a few days). We will try to make this clearer in upcoming versions.
