When I announced the update, the number of people who asked me variations of "how to get website on phone if website on computer" or requested I make the damn thing an app was outrageous.
I had a similar experience. It was mostly lower- and middle-managers who needed to put their mark on something visible.
I responded with, "Tell me what features you want the app to have that the web site doesn't; or is this a vanity project?" The "vanity project" line is what made people re-think what they were asking.
When that didn't work, I pointed out that they'd have to hire an entire new team to do the app, and gave them a high six-figure number to accomplish what they wanted.† That always worked.
