I believe they are referred to as PWA or progressive web app. I’m using Voyager ( formerly wefwef) right now and it’s a pretty solid experience. Been bouncing back and forth between this and Memmy since day one. Voyager is my favorite because it feels like Apollo.

It will open the page in a browser that only runs that one page, there is no “url bar” etc., making it feel more like an app.

Mostly. But it is launched in a different instance of your browser, so it doesn’t mix with it. Becoming more convenient for some cases.

This isn’t a shortcut. It’s an actual app with access to system resources on your phone that a website wouldn’t have access to.
