This is a paid app – Learn Japanese! - Kanji Review

So, if you’re going to charge money for any use of the app, I would recommend being up front about it. Discovering that after download and the first lesson is incredibly frustrating. And I KNOW that you’re going to say “it’s just a trial period, so that people know if they like the app or not”, but regardless this app is not upfront about it. I would prefer some notification in the description or something, so I don’t have to waste my time downloading an app when I don’t want to pay for one.
