Which hits the problem pretty well, right? To do something efficiently on an iPhone, buy a Mac.

I was trying to be helpful. I was responding to someone else who said they have a Mac. But, if you want to relate it to the title, I don't believe there's any technical limitation to developing an app for Windows that can help you transfer files from an Iphone. And as far as I remember, the Android transfer app on Windows (or maybe Mac) is pretty bad as well. Maybe the issue is that there's no money to be made from this, so nobody develops nicer apps. In general I do agree that Iphones are easier integrated with Macs, I personally don't have a problem with that
