I already have a problem with having too many browser tabs open plus it's easier to switch between my browser app and another app than between tabs if I want to look something up or something while reading and replying to stuff on Lemmy.
Progressive web app. You can install the website as an app on your phone. It creates an icon on your home screen for it and when opening it it's like a separate app, that isn't your browser.
Its written as a website really, the only way that would work is to make a wrapper for it, and it wouldn't really change anything. It would just be an app that opened a web page.
I guess it would help discoverability since you could put it on the App Store
