An iPad wireframe is a basic visual representation of how an app will look and function on an iPad. Creating a wireframe is a useful step between along the way from brainstorming to developing an app. Wireframing is a technique for designing a website's structure. A wireframe is a diagram that shows how content and functionality on a website should be laid up, taking into account user demands and journeys. Early in the development process, wireframes are used to build the basic framework of a page before visual design and content are added.
