Prototyping is easily accessible to virtually anyone with InVision. This free tool lets you design prototypes for a mobile device, web or other work. It also lets you collaborate on projects using your mobile device. The web-based tool is registration-based with an attractive dashboard to design, view and comment on prototypes.
InVision?s dashboard is clean and professional, and it looks relatively nicer than similar products like Marvel and Justinmind. The layout is simple and clear, making it easy to use thanks to large thumbnails and tools placed at the bottom of the screen. Overall, it features an intuitive design that is easy to work with. There is a demo video and three demo projects to get you using the application. There are several handy tools, including a preview mode, a history mode to see earlier versions of your project, a build mode that lets you click and drag hotspots, and a comment mode so users can leave comments or add sketches.
InVision is available with Free and Pro accounts. The Free version includes most of the same features as Pro, although you are unable to download your projects or create more than one project. Despite these disadvantages with the Free version and a small learning curve when starting to use InVision, the application is a great option for prototyping.
