Human Interface Guidelines (HIG) refer to a software development document that provides app developers with a set of recommendations and specifications. Its main goal is to ensure developers create visually and functionally consistent, intuitive, and accessible digital interfaces with an excellent user experience.

Most guidelines are limited to defining the visual design and behavior of applications in a particular desktop environment or operating system. For example, the iOS section of Apple’s Human Interface Guidelines focuses on design principles, the look and feel of UI elements, navigation, typography, and other conventions specifically for mobile Apple devices. These guidelines help developers create apps that feel native to iOS and align with user expectations for the platform.^[1]
