Simply put, Jiggy is the easiest way to create applications for the iPhone (or iPod Touch). With just Jiggy and a browser, you'll be able to write an awesome iPhone application in a matter of minutes. JiggyApps run natively on the iPhone, so there is no messing around with HTML and the limitations of Mobile Safari. At the same time, you don't need a compiler or even a Mac, because JiggyApps are written in JavaScript.
Jiggy comes with a browser-based Integrated Development Environment that is both powerful and easy to use. You just run Jiggy on your iPhone and it will URL you. Then, on your computer (Windows, Mac, Linux, C-64) point your browser at the URL and in minutes you will have a shiny new JiggyApp up and running. http://jiggyapp.com/
