We found that the usefulness of your app is limited by the minimal amount of content or features it includes. We only observed a limited task manager, which is well represented on the App Store. 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. Can you guys help me with explaining what does this error mean please? I’m building a collaborative task management app for people who live with roomies or partner but I’m not sure what does this error mean exactly. Thanks in advance!
