I started using mockupscreens 5 years ago. It is easy to use. It can combine screens. I can also use it to prepare patent diagrams. Now I have updated it to the newest version. It has more powerful features, for example, slideshow, which is very helpful for real-time display of mockup.
MockupScreens is a good product, it can quickly create mockup screens. It doesn’t take much space. It supports scenarios and can be published to HTML pages. However, the user interface has some annoying drawbacks, for example, there is no undo option, and it does not allow me to align multiple components. Besides, it is a little hard to use.
Nice deal. Coupon works.
