If only the web made it easier to completely revamp someone else's pages... Reddit is a great example - on mobile, I still use the "reddit is fun" application, which is a solid piece of work. It's lighter than the old Reddit, not to mention the shitshow the new Reddit is. It has much better UX than the webpage. I'd use it on my PC if I could. All this is possible, because right now, APIs change slower than webpages, so if a service is publishing a functional enough API, there is a way to fix problems with the official interface.
