I found a lot of people asking me this question, which framework is better Sencha Touch or jQuery Mobile. Let me first tell you, talking about Sencha Touch and jQuery Mobile is like asking which one is better for server side web development, PHP or Java. While both of them can be used for same purposes in reality they are used for completely different purposes. Where Sencha Touch is optimized and built to run exclusively on web-kit mobile browsers jQuery Mobile is built to globally work all around good on an available HTML browsers. This is more praise for Sencha Touch then jQuery Mobile, it may sound different but Sencha Touch’s optimization is probably this single best thing that makes it shine that much useful. Hybrid mobile applications made from Sencha Touch will run extremely fast and fluid almost native like. At the same time jQuery Mobile covers completely different market segment. Unlike Sencha Touch which is built to work only on web kit browsers, jQuery Mobile will run on pretty much anything as long it supports HTML5 standard. It doesn’t matter are you running it on a Windows, Mac OS, Android, iOS it will run just fine and that makes it appealing to a broader specter of users.
