The Reader iOS developed by Sony has not received approval from the App Store. Of course, the most important reason for the lack of approval; The product is purchase in a different location, rather than the App Store. Therefore, we can say that the App Store does not approve anything that can be obtained from different places other than its own site. Frankly, I think it would be wrong not to think that the App Store is right on this issue. After all, if a product is to be sold through a different location, I think that the App Store cannot be expected to host this product. Whereas; It must have adopted this idea as the main idea in the App Store, as it did not give approval for Sony Reader .
