Differences between MockFlow's web and desktop apps
The desktop app is basically an extension of the web app that provides all online features plus improved performance, native keyboard shortcuts, native application menus and easier access. If you are going to spend a lot of time wireframing, we recommend you to use the Desktop client as it uses less resources and its stability is not dependant on the browser. It is available for both Windows and Mac OS.
