Lelesys uses Sencha Touch for its Mobile Development projects widely.
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.
Follows Model – Store – View – Controller pattern
Heavily Object Oriented
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.
UI and Themeing
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.
Third party plugins
Many Third Party Plugins and extensions can be found on the Sencha Market.
Sencha Touch is licensed under free commercial and open source licenses for application development, and a paid commercial license for OEM uses.
Used for building tool
Sencha Cmd, a separate proprietary (but free) utility from Sencha will scan the code, learn the dependencies, remove the unused code, concatenate, minify, and package the app for delivery.
