Hi Dan,
> I would still like to know what the difference is between Insights and Dashboard.
This question was also asked at the Esri Dev Summit last month. We posted this question in a recent Operations Dashboard for ArcGIS blog. From the blog,
"Q3. How does Operations Dashboard for ArcGIS compare with Web AppBuilder for ArcGIS and Insights for ArcGIS?
A3. Operations Dashboard for ArcGIS is the premier app for creating sophisticated dashboard apps. It offers precision charting and visualization options and uses a new “dashboard” item type in ArcGIS Online and ArcGIS Enterprise 10.6.
Web AppBuilder for ArcGIS has a ‘dashboard’ theme layout option, where you can create a dashboard. You can use the Infographic widget to create simple charts and visualizations quickly and easily. You can also incorporate additional functionality such as editing and geoprocessing in your apps. Existing Web AppBuilder users will likely choose this option to create dashboards.
Insights for ArcGIS is designed for both spatial and non-spatial analysis and data exploration. The analysis results are displayed in maps, charts, and tables on a worksheet – these can be interpreted to be a “dashboard”, but not in the traditional sense. The distinction here: this app’s focus is for data discovery and analysis."
While there is some functional overlap between the 2 apps, they are different and meant to be used for different use cases, as discussed in the blog answer. Insights for ArcGIS offers more charting options, but does not have a real "presentation" mode, all of its cards are simply displayed on a worksheet. Operations Dashboard has fewer chart options, but gives you many more options on configuring various aspects of the chart and is meant to be a data "presentation" app.
Hope this helps,
