My app has been rejected (several times now) on ground of 4.2. Design: Minimun Functionality.I'm not getting any useful comments on what they're expecting to see changed to get it approved.This is what they say:We still found that the usefulness of your app is limited by the minimal amount of content or features it includes.We encourage you to review your app concept and incorporate different content and features that are in compliance with the App Store 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.I've created an app that allows users to create Current Reality Trees, something business can use to help them with their business growth. Based on the work of Eliyahu M. Goldratt. As far as I know there is no other app that lets you create CRT's, so I'd say it enables people to do something they couldn't do before or in a way they couldn't do it before.Since the first rejection on this same point I've added iCloud synchronisation, Possible solutions lists (a next step after creating a CRT), better usability, color tags and a way to collaborate on CRT documents.I'm running out of ideas on what to add and I want to avoid the app becoming bloatware.If you'd like to can try the app via TestFlight: https://testflight.apple.com/join/4Az1fSt5Also something I did, let potential users try the app and add functionality based on their suggestions.Does someone have a suggestion on how to move forward in this situation?
