One can easily extend that logic by saying something that is running Cordova is giving a native GUI to a iOS or android application, because all of it is natively rendering on the device. Usually it means people are running the widgets that are coming from the vendor's toolkits. Windows: Win32/WPF, OS X: Cocoa, iOS: CocoaTouch, Android: etc. and so on. That distinction is somewhat important because it also means the easiest way to get stuff like that running is typically with the language those libraries are written in: C++, Objective-C (or now Swift), Java, etc. It's like the holy grail of write once, run everywhere. Write it in one language and somehow have it run on the native (vendor) toolkit on every platform out there.
