What insights app is that? I don't think we have an official one.
I found it on the playstore when looking for a mobile app for itch.io I assume it's a third party app someone made. It's the result the playstore redirects to it you search up itch.io.
I decided to search it up and it seems like it also has a page on itch io as well: https://lumin7.itch.io/itchio-insights
