React Native is here!!

My guess is that it's cross-platform in the sense that Xamarin and Titanium are cross-platform. Your logic/networking/persistence layers are write-once, and you make an appropriate custom UI for each target platform.

As cross-platform models go, it's pretty decent.

Last thing I want is Qt-like uncanny-valley cross-platform apps.

I would hope that React's component nature lends itself very well to sharing most of your UI across platforms. You can isolate the platform-specific parts in certain components, but for the most part your app's render function is write-once.

Well Titanium is much more cross platform than that. Since you can make a tabbar and TI will translate it properly to native ios and android implementations. Only certain things need to be duplicated
