Apple rejected Readability’s new application based on their new subscription and in-app purchase policy.
Readability’s new service allows readers to “subscribe”—pay them however much a month the reader wants, and Readability gives 70 percent to any websites the user adds to their queue or uses their minimizing functionality on. Apple rejected their application because they do not use their in-app purchase functionality.
This isn’t very surprising and will not be the last of its kind until Apple revises their policy.
