Adobe Shadow is a new tool currently developed by Adobe that provides developers a way to inspect and debug from their desktops wirelessly and synchronously across multiple devices. The Adobe Shadow desktop application listens for changes in a URL location in the browser. When a change occurs, it pushes the new URL out to all wirelessly connected devices immediately so the changed content is seen on the devices immediately. In this blog post, Holly Schinsky provides step-by-step instructions on how to use Adobe Shadow to inspect and debug your mobile code.
