Sizewise is a simple but indispensable part of any designer's or developer's toolbox. It allows its users to test their products on a variety of different screens simulated directly on their desktops, diminishing the need for testing with physical hardware. Sizewise is easy to use and works out of the box with popular software including long-standing industry standards like Adobe's Creative Suite line of applications.
