I find it much easier to install a web app from the website than having to find anything on the App Store. There’s nothing easier, it’s only 2 taps when browsing the website, at least on Safari. The process is exactly the same as in iPhoneOS 1.0, when this was the only official way to get applications.

The problem is not that it’s difficult, it’s that the share sheet got bloated and should be completely rethought.
