responsinator.com: Useful Multi-Device Responsive Checker
So your new website is done, but is it responsive? It is? Great, but is it responsive on all devices?
It’s often quite a pain when it comes to checking if a website is responsive on different devices and that’s where responsinator.com comes into play. With a range of different mobile devices, ranging from the iPhone4S to the Kindle, testing your media queries has never been easier.
I prefer responsinator.com to other device emulators because of its simple look, easy use and the fact that I can check and edit responsive coding of local hosted websites.
