Before you lay out your screens, think about the type of app that you're designing and the type of content that you're providing.
You can lay out your app in a variety of ways. Choose the view that makes sense for your app, using the following views as inspiration:
Lets you give an overview of content that users can sort and filter, such as contacts or messages.
Lets you display content in a more visually appealing way by placing images in rows and columns.
Lets users navigate a large canvas of information, such as a map, a game, or an image.
Lets you set the focus on a single item (for example, a contact card, an email message, or a Facebook post).
