Noun review section, please!
Included about 5,000 vocabulary to review. However, the only problem is the lack of a noun level in both the quizzes and in the review sections. As German is a case language, the mastery of declensions is imperative to success. If a noun section were to be included, I think Mr. Arthur would be able to bump the app up to the $4.59 price point with no problem. However, the app is still very helpful without the noun features. It would just be even better with them.
