essential tool for professional designers

I haven’t found anything as capable as this tool for checking apps for color blindness and other visual impairments. The design and measurement tools are also top-notch, fluid, useful and powerful.

A great tool that is made even better with the xScope mirror functionality on iOS.

Well worth the $$ - great value - awesome support and continued development of the tool. Rock solid product.
