ios Application got rejected just for UI

I just uploaded ios application with attractive UI, but the review team of envato thinks UI is not best. ios app is not based only in UI, its based on functionalities also.

I want to ask envato team in your view which is the best design of ios, and why item was rejected?
Can’t you check functionalities, main concept is functionalities only.

Before i uploaded one app which is already in ios and i uploaded in android. The reason was same. DO YOU REVIEW FULL ITEM OR NO?
