Duo is a dual-paned web browser built for Responsive Web Design (RWD) that lets you browse the web in two views: your standard ‘desktop’ view as well as a typical ‘mobile’ view. By seeing these two views at the same time, you’re able to quickly test and work through multiple screen experiences rather than considering them separately.
Whether you’re a designer or a developer, project manager or client, Duo gives you a new tool to make your Responsive Web Design project go more smoothly than ever.

• CONVENIENT KEY COMMANDS
Duo includes tools for clearing your cache and getting rid of those pesky cookies via standard key commands.

• HANDY BOOKMARKLET
Use the convenient bookmarklet in your other browsers to push a site over to Duo. Get the bookmarklet: http://helloduo.com
WHAT IT ISN'T
Duo is designed for Responsive Web Design, not for user-agent sniffing. Duo also only refreshes both views for GET requests. It's probably not a good fit for your POST refresh heavy project, although we are actively looking at ways to accommodate this.

What's New in Version 1.3
Not real mobile view, very limited options...
Just purchased and tried, here is what I found wrong:
1. The mobile view gives you a “frame” of your website, and not the “real view” of it on a real mobile device. In other words, on my mobile phone I can see my complete website page, reduced in size of course, fitting the full screen, whereas on this program I can see just a portion of the screen without size reduction which is not the real view you get on a mobile device.
2. There is no way to access any settings to target specific screen devices. I really expected that!
For me, this app is useless and deceptive. To test my website for repsonsive design, I am going to use a real device.
Almost there ...
I love the simple user interface. And this really helps when previewing fully responsive sites; but if also let you set the user agent … that would make it complete, to me.
