Responsive screen testing tool; free at quirktools.com/screenfly

Mobile phones, tablets, laptops, desktops and even televisions have become sources for scrolling the internet, but websites aren’t always compatible across every device. Is yours? Enter Screenfly, the web app that allows you to see how your web design responds to different devices. Simply type in your URL to view your page—then start testing it. Buttons across the top of your browser allow you to choose different devices, screen sizes and resolutions, and your site will appear in the frame as it would on whichever device is selected. Screenfly is an easy way to see if your website gives your customers the ease of access they need.
