Design patterns — reusable solutions for design problems — create a sense of familiarity and consistency. When users see and recognize familiar patterns, they feel more relaxed about navigating an application.

All operating systems have native design patterns. They work like reusable blocks for solving common problems and saving time.

For example, top tabs, floating action buttons, sidebars, or hamburger menus are common Android design patterns. For iOS apps, you'll probably use the bottom navigation bar, a primary button in the top right corner, and a bottom navigation to display navigation options.^[1]

Design patterns allow for rapid wireframing and create less cognitive load by helping users use functions intuitively.
