Prototyping is a big part of any app or web design workflow these days. You can test both the user interaction (UI) and user experience (UX) before you jump into coding. It's a low-risk, low-impact activity with many long-term rewards. And with Marvel, the free web and mobile prototyping app, the process is even easier. In this course, Brian Wood shows how to set up a Marvel app account, design a prototype for an app, link screens, add interactivity, and share your prototype with others for review. Plus, learn how to embed video via links and set up timers to mimic transitions between screens.
