Thank you so much for your kind words and your willingness to help! Below is the full message I received from the App Review team: Guideline 4.2 - Design - Minimum Functionality "We found that the usefulness of your app is limited by the minimal amount of content or features it includes. Next Steps We encourage you to review your app concept and incorporate different content and features that are in compliance with the App Review Guidelines. We understand that there are no hard and fast rules to define useful or entertaining, but Apple and Apple customers expect apps to provide a really great user experience. Apps should provide valuable utility or entertainment, draw people in by offering compelling capabilities or content, or enable people to do something they couldn't do before or in a way they couldn't do it before." One thing I should mention is that I submitted the app with demo content, as the app has not been officially launched yet. Do you think this could be one of the reasons for the rejection? I’ve also attached some screenshots of the app.
