mobble provides mobile related conditional functions for your site. e.g. <a href="https://wordpress.org/extend/plugins/mobble/faq/" title="More examples" rel="ugc">is_iphone(), is_mobile() and is_tablet()</a>.
CSS media queries are great for creating responsive web designs but they do not always provide enough control. There are times when not all of the content, JavaScript or CSS on a page is relevant for a particular device. With the mobble functions you can make these kind of tweaks to your theme.
mobble can also add device information to the body class of your theme allowing you to easily target your CSS for different gadgets.
