When Apple discontinued venerable HyperCard application back in 2004, I chose Runtime Revolution (originally MetaCard) which eventually evolved to LiveCode. I had become proficient in HyperCard's HyperTalk language, so I felt comfortable with Revolution's Transcript language, i.e., LiveCode's Script language. Just like HyperCard, LiveCode offers what they call "Edit live applications" with "run" and "edit" modes, meaning that there is no need to "compile" like any other computer languages.

Livecode is an extremely viable cross-development app platform. It allows a "build once, run everywhere" codebase to be deployed across desktop (Windows, Mac, Linux) and mobile (iOS and Android) as well as HTML5. Very stable, large userbase.
