Built with responsive web design testing in mind, test refresh allows you to automatically track a browser window on a desktop, refreshing the URL on your mobile device without having to manually pick up the device and hit refresh.

You simply install a (free) browser extension and enter the details as displayed in-app to create a connection between your desktop browser and the test refresh application; everything else is then automatic.

The chrome extension can be found here: https://chrome.google.com/webstore/detail/test-refresh/gbkkkkcbfhnhohdiojphpllbfhbkebkp

You do not even need an internet connection to use the app - as long as your mobile device and your desktop are on the same network, and your device can load the same URLs as your desktop, you will be able to connect the two and start testing your websites for responsive layout, in real-time.
