I'm looking to create mobile app similar to the Citizen Problem Reporter, but with the map and other reports not visible to the public. So the app should be pretty basic, take a photo, report an issue. And then have the map and all the data available behind the scenes for the organization. Another component would be custom alerts that periodically go out to app users. Does something like this exist?
Would downloading the source code for citizen reporter make it possible to create this app?
Would it be better to look for a app builder outside of ArcGIS Online? Any suggestions?
