We've been rejected for the same reason last month, it was against the Apple guideline since most of the contents aggregated from the Internet and there is a lack of the native iOS functionality.
Apple are still rejecting the app based on the 4.2.2 guidelines stating:
"We noticed that your app only includes links, images, or content aggregated from the Internet with limited or no native iOS functionality. We understand that this content may be curated from the web specifically for your users, but since it does not sufficiently differ from a mobile web browsing experience, it is not appropriate for the App Store."
In this regard, we've to make a minor incremental change at least in order to try and get this through with good luck. I think that way we could ensure your app is compliant with all sections of the App Store Review Guidelines and the Terms & Conditions of the Apple Developer Program.
Below are a few tried and tested ideas to get your app approved:
Catalogue category - make your app look and feel more like a category and submit it under this category
Great user experience - offering a feature and content enabling people to do something, such as:
enable push notification
add camera
send email option included
make a call from the app
display your social media channels
Editorial content - audio, photos etc
These above approaches right what Apple wanted - after adding such features they didn't ask any other question on this subject.
