We encourage you to review your app concept and incorporate different content and features that are in compliance with the App Store Review Guidelines.
For app design information, check out the following videos: “Best Practices for Great iOS UI Design” and “Designing Intuitive User Experiences,” available on the Apple Developer website.
You may also want to review the iOS Human Interface Guidelines for more information on how to create a great user experience in your app.
If you cannot - or choose not to - revise your app to be in compliance with the App Store Review Guidelines, you may wish to build an HTML5 web app instead. You can distribute web apps directly on your web site; the App Store does not accept or distribute web apps.
HTML5 is the major new version of HTML and enables audio and video to play natively in the browser without requiring proprietary plug-ins. Using HTML5, web apps can look and behave like native iPhone and iPad apps, and using HTML5’s Offline Application Cache, a web app can work even when the device is offline. With web apps, you have flexibility to deliver as much or as little functionality as you desire.
To get started with iPhone or iPad web apps, please review the Safari Client-Side Storage and Offline Applications Programming Guide.
