For instance parking payment apps, mobile ticket apps etc. that you download when in vacation and could 100% be web only, or a PWA if Apple was onboard with it, instead of their “light app” thing.
Or I had some of the government services apps not exposing text labels as selectable, which is a pain if you need to search for it. Same thing when you want to print/save the screen, you end up with a single screen png instead of potentially a fully scrolled and text including pdf. All these features could be coded in the app, but realistically devs don’t give a damn as it doesn’t bring much praise or money.
