The most useful LTD's I have are the ones I use the most frequently, and have changed my daily workflow, this is one of those apps.
I have tons of analytics tools, GA and custom Data Studio Reports for every client, but this one is just easy, I can see visitors and primary conversions for a list of clients from a bookmark that takes me to the dashboard, I actually bought this to track user sessions, but I have yet to really dig into that side of it, but I use this every day just to look at traffic and conversions for my key clients and my sites.
