Hello, Thank you for your patience as we considered your appeal. The App Review Board determined that the original rejection feedback was valid. Your app does not comply with: Design 4.3 We continued to find that your app shares a similar binary, metadata, and/or concept as apps on the App Store from other developers, with only minor differences. Submitting similar or repackaged apps is a form of spam that creates clutter and makes it difficult for users to discover new apps.
