Technically cute, but works only for non-UI modules, which comprise approximately 4% of a mobile app.

Anything with a large backend is likely an intensive game, and aren't those cores written in native C/C++ anyway?.

Someone please take an app in Objective C, convert it to JS with route 66, convert to Java with (?) And convert back to Obj C with this tool, and share.

Where on earth did you get that number?

UI code in a well-structured application is a thin-shim on composed, testable backend code. It should be the least of the code, by far.

This is highly dependent on the app. All iOS projects I've worked on have been 50-80% UI code sitting on top of a pretty thin set of persistance and networking classes.

That sounds like too much logic is in your UI.
