These are some examples of how you can transform a normal web page into a Web App using jQuery Mobile, that I created based on well known native applications

I make the boring things look pretty

The examples in the slider are real screenshots taken on my iPhone 4S and use jQuery Mobile – v1.1.1 to demonstrate just how customisable the framework is. In the smart viewer you can see the demos working, remember though that the display varies slightly from that of a smartphone.
‘Seriously cross-platform compatible.

jQuery Mobile framework takes the “write less, do more” mantra to the next level: Instead of writing unique applications for each mobile device or OS, the jQuery mobile framework allows you to design a single highly-branded responsive web site or application that will work on all popular smartphone, tablet, and desktop platforms’

Skin design

The examples use heavy css customisation but if you are just looking for a new colour scheme you can create this quite easily yourself. If you visit themeroller.jquerymobile.com you can create your own skins for jQuery templates quite easily with their custom built tool. There is also a pretty good tutorial from the jQuery people here
