POP is an iPhone and iPad app that allows users to create interactive app designs and prototypes. With a simple design mode and integrations with Unsplash, Iconfinder, and Randomuser, users have access to over 1 million icons, fonts, stock photos, and avatars to enhance their designs.

For those who prefer sketching their ideas on paper, POP also supports the ability to take a photo of your sketches and add them to your project.

Once the designs, sketches, mockups, and wireframes are ready, users can turn them into interactive app prototypes. By linking each screen together using touch areas and adding realistic transitions, users can create a demo of their app ideas.

Sharing and collaboration is made easy with POP. Prototypes can be shared with any device or desktop browser using Email, SMS, Twitter, and Facebook. Additionally, everything is synced to the user's Marvel web account, providing access to prototypes from anywhere.
