I was also confused by this and resigned to not using it because I’m a silly goose who doesn’t understand what a web app is… but then saw someone link to the wefwef website, figured I’d give it a shot, and turned out it’s surprisingly simple. Just go to the link below, download, and now there’s an app on my home page for wefwef. I don’t know the difference between it and my other “normal” apps, but it does seem to work! Lol

Link: www.wefwef.app

P.S. I think I mightve clicked on “settings” at the bottom of the screen and there was an “install app” button there if I remember correctly?
