You are in luck! I'm one of the developers working on the Wanderful app and it is very much being built. You can check us out at http://wanderful.co/

Cool, just installed it. Can you say anything about the platform it was built on, Cordova?

The current version of the app was built with Titanium, but I'm not sure that I can recommend it for nontrivial apps. The API still has plenty of gaps and the platform isn't as 'cross-platform' as we had hoped (there are plenty of controls and properties that are platform-specific.)

RequireJS or one of its AMD cousins would have been all that you needed to handle the "too few files" problem that prevented you from scaling the project's development.
