Sencha is a new framework that is geared towards developers of mobile applications. Simply put, using this mobile app framework any developer can make a web application feel as if it were a native app, ready to be used both in iPhones and Android devices.
The flexibility of Sencha is made evident when you learn that it has been built using web standard HTML5, CSSS3 and Javascript. A very wide range of components can be used, such as the one that lets you incorporate Google Maps and geolocate any user’s position. And visual components are likewise featured. But one of the most flexible aspects of Sencha is how it enables you to associate non-standard touch events to any element you have created. In practice, this will let you create the kind of interaction that a user of a smartphone always looks for, as swipe or double-tapping the screen is only natural today.
Sencha can be downloaded free of charge (it is currently in public beta), and all the documentation you might actually need to get it in motion can be instantly procured on the site, too.
