Sencha Touch is the world's first app framework built specifically to leverage HTML5, CSS3, and Javascript for the highest level of power, flexibility, and optimization. We make specific use of HTML5 to deliver components like audio and video, as well as a localStorage proxy for saving data offline. We have made extensive use of CSS3 in our stylesheets to provide the most robust styling layer possible.
Altogether, the entire library is under 120kb (gzipped and minified), and it's trivial to make that number even smaller by disabling unused components or styles.
The World’s Best Devices
Sencha Touch is a cross-platform framework aimed at next generation, touch enabled, devices. It's currently compatible with Apple iOS and Android devices, and very soon with RIM Blackberry 6 devices. Together these devices represent over 95% of current US mobile traffic. Android and Blackberry developers can also make use of special themes we've created just for those devices. With the ever-rising number of Android models and the widespread popularity of WebKit on mobile devices, we expect our supported device list to grow very rapidly.
