Adobe recently released a new tool called Adobe Shadow, that make it easy to test web applications and sites across a spectrum of devices.
The Adobe Shadow tool has multiple components, one running on your mobile device, on your computer, and one integrated in your browser — currently only Chrome is supported. It allows you to link multiple devices (iOS or Android) running the Adobe Shadow application with a computer, and offers synchronized browsing between these devices. So as you open a page on your desktop / laptop browser, it opens on all linked devices. This has obvious benefits while testing applications.
Adobe Shadow is currently an Adobe Labs technology, which means that while it has been released for the public to play it, it is still in development, and public feedback might affect the final product. In fact this second release of Adobe Shadow has taken into account some of the public feedback and requests for fixes.
