Apple Store APP reject

Hi, all,

My ios App was rejected by Apple.
" Guideline 4.2 - Design - Minimum Functionality

Your app provides a limited user experience as it is not sufficiently different from a mobile browsing experience. As such, the experience it provides is similar to the general experience of using Safari. Including iOS features such as push notifications, Core Location, and sharing do not provide a robust enough experience to be appropriate for the App Store."

Here is the brief description of my App:
The main activity is a WebView, and the WebView will be changed when the iphone approaches different Estimote Beacons. (iBeacon - Minor)

Please give me some advice!!!

Huge thanks!

It is a simple app. The main idea is let the user to see different contents in our exhibition.
