InVision is another online app that works similarly to UXPin, except with an emphasis on design. It includes all the tools you need to go from wireframing to UI designs. And comes with lots of useful tools for better collaborations and prototyping as well.

Much like UXPin, InVision also has tools for making objects in your designs interactive. However, it’s much more simplified and doesn’t allow you to implement advanced states as UXPin does.

5. Figma

figma
  • Price: Free / $12 per month
  • Best For: Web and mobile app interface designers

Most designers are already familiar with the popular web-based UI design tool. Even though Figma is commonly known as a UX design app, it has tools for rapid prototyping as well.

sketch
  • Price: $99
  • Best For: Mobile and web UI and UX designers

Sketch is one of the best apps available today for designing all types of user interfaces. It’s like a more advanced and widely supported version of Figma. The only reason we ranked it below Figma is because of the fact that it’s not cross-platform.

Sketch has a wide community and as a result, there are thousands of templates and UI Kits out there you can use to prototype apps and designs faster. The only downside is you need a Mac computer. This makes collaborating on projects a bit difficult as well.

Main Features

  • All-in-One editor for wireframing, prototyping, and designing app and web interfaces
  • Draw and editor vectors or use pre-made component libraries to design faster
  • Create interactive elements and add animations to your designs
