I agree with you, but Anki is a generalized flashcard SRS memorization tool, not specifically made for learning Japanese, so it's not within my area of critique; I'm thinking of apps similar to Duolingo. It works extremely well because it helps you memorize very efficiently. One of the few applications that will indeed boost your learning by a lot. Anything requiring manual input rather than a simple Again or Good button choice tends to be worse. Any Anki deck requiring manual input as an answer should not be used.
