Is there an instant app that lets you use the lasso tool from dashboards to circle areas on the map..

I'm looking for an instant app that will let me circle areas on a map and have the layer data from within that circled area populate into a list or chart.  I'm hoping to make something less clunky than a dashboard.

 

More specifically looking to be able to drag a box or lasso around an area to give a total structure count within the given area, not just within the visible map extent.

 

Thanks!

@JHolbrook The Instant App, Zone Lookup, allows the app user to draw an area and return features within the area/zone in list form, which includes a count. It also has the ability to generate statistics on those features, if you'd like.  To set the app up to work this way use the following settings:

- In step 3 of express mode or the Zone Lookup > Options section, enable "Features within zone" and then toggle on "Draw a zone".

- Statistics are available in full setup (disable express) under Zone lookup > Statistics

Beth, 

 

That almost worked perfectly.  The problem I'm having is that I'm using the USA Structures layer ( https://arcg.is/1DHTXu0 ) and wanting to see a compressed breakdown of structures by type within the given area.  What I'm getting is either just a big list of all of the individual structure pop-ups in the side bar, or just a total count of all structures within the area below.  The statistic options are limited to integers, it seems, so the building occupancy class (Residential, commercial, etc) can't be factored into one of the statistics.  If I could select the string fields in the drop down, I could simply have it do a count and just have a counter for each individual occupancy class, but every single one of options for selection are relatively unique (sq ft, lat, long, elevation, a unique building id number, etc).  Any clue how I might get around this?  In my dashboard i'd use a pie chart and just have grouped values with occupation class as the group and then get counts on each of a given type within that group.
