Guideline 4.3 - Design
We noticed that your app provides the same feature set as other apps submitted to the App Store; it simply varies in content or language, which is considered a form of spam.
The next submission of this app may require a longer review time, and this app will not be eligible for an expedited review until this issue is resolved.
