Creating an iPhone wireframe, like this example, allows you to sketch out the planned interface of a mobile app which can help you visualize each element and convey your ideas more clearly. Wireframing is a method of structurally designing a website service. A wireframe is a visual representation of how content and functionality will be laid upon a page, taking into account user demands and journeys. Before visual design and content are included, wireframes are used early in the development process to determine the basic framework of a page.
