About Igor Ješe, the Author of MockupScreens

Igor Ješe works in software development since early 1990s, with emphasis on software requirements and development methodology. He is a certified Software Requirements Expert and Project Management Professional, and also the author of Mockup Screens - a popular tool for quick GUI prototyping.


Create five screens in ten minutes without any programming knowledge or prior training!

Experiment interactively with your clients, and quickly visualize scenarios of your application, even before the coding has started.

  • Show screen mockups to your customers and get valuable feedback from them.
  • Speed up design and development by bridging the gap between clients and developers, immediately visualizing the application being built.
  • Clearly understand your users by turning abstract ideas into a detailed prototype.
  • Manage user expectations by building on user feedback, using MockupScreens to demonstrate the design and function of the system.
  • Clarify requirements and set the priorities right, to avoid rework later.
