Jo is a mobile framework, written mainly in HTML5.

As you might have guessed from the picture, Jo is a cross-platform framework: it supports iOS, Android, Symbian, Safari, and other platforms.
It’s merely 9kb when gzipped, and ~34kb when minified; thus, Jo is one of the smallest mobile frameworks out there — plus, the framework is entirely dependency free.
You can use Jo together with PhoneGap or other frameworks for even better results.
But what’s really cool is this, though: you can debug Jo’s mobile apps using merely a WebKit browser.
