text: It is used by Web developers to develop user interfaces for mobile web applications that look and feel like native applications on supported mobile devices. It is based on web standards such as HTML5, CSS3 and JavaScript. The goal of Sencha Touch is to facilitate quick and easy development of HTML5 based mobile apps which run on Android, iOS, Windows, Tizen and BlackBerry devices, simultaneously allowing a native look and feel to the apps.
  Touch inherited the best of Ext JS, a versatile enterprise-level workhorse, and took it to the next level by upgrading to utilize ECMAScript5, CSS3 and HTML5 best practices. That makes Touch different from Ext JS in the way that it no longer supports older browsers, but the functionality it offers is as good as it gets.
  It includes a set of graphical user interface GUI-based controls (or components) for use within mobile web applications. These components are optimized for touch input.
  It Offers many widgets - Component, Container, Form, various Fields to more complex Carousel, Lists, Pickers, Charts, Grid, and much more.
  Sencha Touch has an inbuilt DOM manipulation interface which negates the dependency on other UI frameworks like jQuery.
  Sencha Touch framework is UI-centric, developers usually wind up modifying the default theme instead of writing the whole UI from scratch, which in turn requires some familiarity with the theming system.
