Marvel – Free & Unlimited Prototyping for Designers

Marvel App is a really simple tool that turns images and design files into interactive, sharable prototypes without needing to get your hands dirty with coding. Prototypes can be created in a few clicks and work on any device with a browser, including mobile, desktop, TV and games consoles.

The beauty of Marvel is that it’s completely powered by Dropbox, meaning that every change to your image is synced to the prototype. You’ll never have to keep reuploading files every time you tweak the design, Marvel just does its job and gets out of the way.
