[Question] Why isn’t there a LessWrong App? Is a “blog-app” sustainable/​useful for a community?

I am a newbie lesswronger, so it might be an already asked question, but I can’t find an answer in the FAQs. I also don’t have any idea of how many resources are needed to support a blog-app, given an already developed site/​community. I would be glad if someone could explain the issues/​difficulties, and why the community never exploited this channel to acquire new users/​better accessibility (I would love to have an app instead of using the browser to browse the site).
