Adobe Shadow is a cross-platform app for Windows, Mac, Android and iOS-powered devices that lets front-end developers remotely test, debug and inspect their web projects on various screen sizes and OSes.
The method involves installing Adobe Shadow desktop application and Chrome extension on PC, and the mobile client on your smartphone/tablet. Provided all the devices are sharing the same Wi-Fi connection, all you need to do is pair them to the computer using a unique passcode. Form thereon, you can remotely browse and sync your projects across various devices. Any changes made to the original code of the website are immediately reflected on each connected device.
If your Webpage look great on the PC, but horrible on iphone or android devices, you can use the Chrome browser's built-in debugging tools to tweak your code until you have achieved cross-platform perfection.
The Shadow app requires atleast iOS 4.2 (iPhone 3 or greater) or Android 2.2. Shadow app for windows and blackberry are not available as of now.
