Napkin is a lightweight user interface design tool made for mocking up quick ideas directly on your iPhone. The program is free to download from the Apple app store.
Napkin's main use is sketching out quick concepts whenever they come to you, rather than waiting until you're back at your computer. In this short tutorial we'll walk through mocking up a quick profile view.
01. Add a Layer to the Canvas
This is where you start when you open the app. The sidebar is revealed by an edge swipe on the right of the screen. Here you can select layers to add to the canvas, configure the grid size, and control the appearance of the status bar. There are four main types of layers you can add: Rectangles, Photos, Text, and Icons. Let's start by adding a rectangle.
02.Double Tap to Edit
Once you have the rectangle on the canvas, drag it around to position it as you please. Every shape has properties which you can change. To show the controls for these, you can double tap any shape and contextual controls will appear. Once the controls are up, change the color to black, then drag the controls back down to dismiss them.
03. Add an image
Just like rectangles, images can be edited by double tapping them. You can also replace the image with anything off of your camera roll, but by default there's a nice photo of the grand canyon for you. Position the photo on top of the rectangle and lower the opacity so it's dimmed. You can also change the appearance of the status bar to be white at this point in the sidebar menu.
