In that case it would not have changed anything. Instead of seeing the Cloudflare page in your regular browser you would have seen the same page in this app, since this app is only a dedicated browser for kbin.social, nothing more.
This app is like Firefox, Chrome, Edge, Opera, but unlike them it only loads by default kbin.social. I think Datas_Cat_Spot's comment explains the only advantage this app has over any other browser for browsing the site.
