Maybe HN users, but an increasingly overwhelming percentage of the general population prefers to download an app to do something instead of using a mobile website.
Various industry surveys, like the one from comscore in 2019 suggest otherwise. IIRC it found that most American phone owners install only 1-2 new apps per year. I think they would've gone to more new websites than that.
That study doesn't imply what you suggest. Yes, most Americans install 1-2 apps per year: Facebook, Instagram and similar, and that's all they ever use. That segment of the population doesn't use the mobile web either; they spend all of their time in 1-2 walled gardens and you're not going to reach them with an app or website.
Couldn't you create a web-first app, then have the "app" that appears in the app just install a launcher icon that launches a browser window pointing to your website? This method (PWA?) I believe also lets you launch the browser without the browser control bar at the top (so it appears as a local app).
The best part of this is even if your app gets banned from the app store, it is still accessible to anyone that wants to bookmark your URL, and I believe that users can also install the local PWA icon without having to go through an app store (I may be wrong about that, just starting to learn about PWAs and what is currently possible, and what is coming up).
You seem to know what you are talking about, but from my personal experience this does not see correct. To me, it seems that it used to be that way, but now people only download apps for very specific purposes.
Do you have pointers to data on this subject? I am very interested in this subject!
