Good use of a data set and illustrates what's possible.
I put together a tutorial on how to create a famo.us (awesome framework for high-perf web apps) and use ManifoldJS to deploy it to several platforms. In this case, iOS.

For a web app to really stand out from the web site it is coming from, it should offer some sort of benefit to the end user that could not be found on the site itself.
So a web app can be a lot more than just a wrapped, simple app.

You can always go in and edit the Cordova project that ManifoldJS returns and add your own images for icons and such. Not sure if ManifoldJS currently supports this out of the box just yet, though.
