Cross-Platform Design (iOS vs Android)
Designing a mobile app isn't a one-size-fits-all process. What works natively on an iPhone will feel broken and alien to a user on a Samsung Galaxy.
HIG vs. Material Design
Every platform has strict guidelines that dictate how elements should look and behave:
- Apple HIG (Human Interface Guidelines): Emphasizes depth, translucency, and a physical feel. Navigation usually relies on a bottom tab bar and a physical swipe gesture from the left edge to go back.
- Google Material Design: Emphasizes flat colors, stark shadows, and paper-like surfaces. Navigation often utilizes a Floating Action Button (FAB) for primary actions and relies on the Android system's universal hardware "Back" button.
The "Don't Make Me Think" Rule
Expert UX designers never force custom navigation patterns when a native one already exists. If an iOS user expects a settings menu to be accessed via an icon in the top right, placing it in a hidden hamburger menu on the left increases their cognitive load. Respect the platform.
