Engaging user experiences are built on a foundation of solid interface design. Before you start coding, consider these fundamental design concepts for building clean, efficient interfaces for a broad set of users.
Create a layout that fits the screen of a device. Users should see primary content without zooming or scrolling horizontally.
Use UI elements that are designed for touch gestures to make interaction with your app feel easy and natural.
Create controls that measure at least 44 points x 44 points so they can be accurately tapped with a finger.
Make sure there is ample contrast between the font color and the background so text is legible.
Don’t let text overlap. Improve legibility by increasing line height or letter spacing.
