A few days ago I uploaded an application for approval to the Apple Developer Console and they rejected it for the following (original text in English):
Guideline 4.2.2 - Design
Thank you for your resubmission.
We noticed that your app's main functionality is to market your service, with limited or no user-facing interactive features functionality Apps that are primarily marketing materials advertisements are not appropriate for the App Store.
Please see attached screenshots for details.
Next Steps
We encourage you to review your app concept and incorporate different content and features that are in compliance with the App Store Review Guidelines.
We understand that there are no hard and fast rules to define useful or entertaining, but Apple and Apple customers expect apps to provide a really great user experience. Apps should provide valuable utility or entertainment, draw people in by offering compelling capabilities or content, or enable people to do something they could not do before or in a way they could not do it before.
Could you tell me how to solve this?
I can not understand what the problem is because the user does not pay for this app.
I would appreciate your help since my English is very low.
