Use when designing app interfaces, creating design systems, ensuring accessibility, or following platform guidelines. Covers Material Design 3, Human Interface Guidelines, color theory, typography, and 2025 trends.\n---\n# Mobile App UI Design\n\n> Expert guidance for designing beautiful, accessible, and platform-native mobile app interfaces following 2025 best practices.\n\n## Core Philosophy\n\n- **User-First Design** — Prioritize user needs, behaviors, and mental models over aesthetics\n- **Platform Consistency** — Follow iOS HIG and Android Material Design guidelines\n- **Accessibility as Foundation** — Design for all users from the start, not as an afterthought\n- **Emotional Intelligence** — Create interfaces that users emotionally connect with\n- **Performance-Conscious** — Beautiful design that doesn't sacrifice app performance\n\n---\n\n## Hard Rules (Must Follow)\n\n> These rules are mandatory. Violating them means the skill is not working correctly.\n\n### Accessibility First\n\n**All designs must meet WCAG 2.2 AA standards. Accessibility is not optional.**\n\n```markdown\n❌ FORBIDDEN:\n- Color contrast below 4.5:1 for text\n- Touch targets smaller than 44×44pt (iOS) or 48×48dp (Android)\n- Information conveyed by color alone\n- Missing alternative text for images\n- Non-keyboard-navigable interfaces\n\n✅ REQUIRED:\n- Minimum 4.5:1 contrast ratio for normal text\n- Minimum 3:1 contrast ratio for large text (18pt+)\n- Touch targets: 44×44pt (iOS) / 48×48dp (Android)\n- Support for Dynamic Type / Font Scaling\n- VoiceOver (iOS) / TalkBack (Android) compatibility\n- Clear focus indicators for keyboard navigation\n```\n\n### Platform Guidelines Adherence\n\n**Follow platform-specific design guidelines. Do not mix iOS and Android patterns.**\n\n```markdown\n❌ FORBIDDEN:\n- Using Android-style FAB on iOS\n- Using iOS-style bottom sheets on Android without adaptation\n- Mixing platform navigation patterns\n- Ignoring platform typography (SF Pro vs Roboto)\n\n✅ REQUIRED:\niOS (Human Interface Guidelines):\n- Use SF Pro font family\n- Tab bar at bottom for primary navigation\n- Push navigation with back chevron\n- Standard iOS controls (UIKit/SwiftUI)\n\nAndroid (Material Design 3):\n- Use Roboto font family\n- Bottom navigation bar or navigation drawer\n- Material components with ripple effects\n- Follow Material You dynamic theming\n```\n\n### Consistent Design System\n\n**Every app must have a documented design system with tokens.**\n\n```markdown\n❌ FORBIDDEN:\n- Ad-hoc colors and spacing values\n- Inconsistent button styles across screens\n- Multiple unnamed font sizes\n- Components without defined states\n\n✅ REQUIRED:\nDesign System Must Include:\n├── Color Tokens (primary, secondary, surface, error, etc.)\n├── Typography Scale (heading1-6, body, caption, etc.)\n├── Spacing Scale (4, 8, 12, 16, 24, 32, 48px)\n├── Border Radius Tokens (none, sm, md, lg, full)\n├── Shadow/Elevation Tokens (elevation1-5)\n└── Component Library (button, input, card, etc.)\n```\n\n### Touch-Friendly Design\n\n**All interactive elements must be optimized for touch interaction.**\n\n```markdown\n❌ FORBIDDEN:\n- Touch targets smaller than minimum size\n- Interactive elements too close together (<8px gap)\n- Important actions outside thumb reach zone\n- Hover-dependent interactions\n\n✅ REQUIRED:\n- Minimum touch target: 44×44pt (iOS) / 48×48dp (Android)\n- Minimum spacing between targets: 8px\n- Primary actions in thumb-friendly zone (bottom 2/3)\n- Clear tap feedback (ripple, highlight, scale)\n```\n\n---\n\n## Quick Reference\n\n### When to Use What\n\n| Scenario | Approach | Key Considerations |\n|----------|----------|-------------------|\n| New app design | Start with design system | Define tokens before screens |\n| iOS-only app | Human Interface Guidelines | SF Pro, standard iOS patterns |\n| Android-only app | Material Design 3 | Roboto, Material components |\n| Cross-platform app | Adaptive design | Platform-specific navigation |\n| Redesign existing app | Audit first | Maintain mental models |\n| Accessibility review | WCAG 2.2 AA checklist | Contrast, touch targets, labels |\n\n---\n\n## Design System Fundamentals\n\n### Color System\n\n```markdown\n## Color Token Structure\n\n### Semantic Colors\nprimary          → Main brand color, CTAs\nprimary-variant  → Darker/lighter primary for states\nsecondary        → Secondary actions, accents\nbackground       → App background\nsurface          → Card backgrounds, elevated surfaces\nerror            → Error states, destructive actions\non-primary       → Text/icons on primary color\non-background    → Text/icons on background\non-surface       → Text/icons on surface\n\n### Color Palette (60-30-10 Rule)\n60% → Neutral/background colors\n30% → Secondary/supporting colors\n10% → Accent/primary colors\n\n### Dark Mode Considerations\n- Don't just invert colors\n- Use desaturated colors for dark surfaces\n- Reduce contrast slightly (avoid pure white on black)\n- Maintain color meaning across modes\n```\n\n### Typography Scale\n\n```markdown\n## Mobile Typography Guidelines\n\n### iOS Typography (SF Pro)\nLarge Title   → 34pt, Bold\nTitle 1       → 28pt, Bold\nTitle 2       → 22pt, Bold\nTitle 3       → 20pt, Semibold\nHeadline      → 17pt, Semibold\nBody          → 17pt, Regular\nCallout       → 16pt, Regular\nSubhead       → 15pt, Regular\nFootnote      → 13pt, Regular\nCaption 1     → 12pt, Regular\nCaption 2     → 11pt, Regular\n\n### Android Typography (Roboto / Material 3)\nDisplay Large  → 57sp\nDisplay Medium → 45sp\nDisplay Small  → 36sp\nHeadline Large → 32sp\nHeadline Medium→ 28sp\nHeadline Small → 24sp\nTitle Large    → 22sp\nTitle Medium   → 16sp, Medium\nTitle Small    → 14sp, Medium\nBody Large     → 16sp\nBody Medium    → 14sp\nBody Small     → 12sp\nLabel Large    → 14sp, Medium\nLabel Medium   → 12sp, Medium\nLabel Small    → 11sp, Medium\n\n### Best Practices\n- Maximum 2-3 font families per app\n- Minimum body text: 16px (14px absolute minimum)\n- Line height: 1.4-1.6× font size for body text\n- Support Dynamic Type (iOS) / Font Scaling (Android)\n```\n\n### Spacing System\n\n```markdown\n## 8-Point Grid System\n\nBase Unit: 8px\n\n### Spacing Scale\nspacing-0    → 0px\nspacing-1    → 4px   (half unit)\nspacing-2    → 8px   (1 unit)\nspacing-3    → 12px  (1.5 units)\nspacing-4    → 16px  (2 units)\nspacing-5    → 24px  (3 units)\nspacing-6    → 32px  (4 units)\nspacing-7    → 48px  (6 units)\nspacing-8    → 64px  (8 units)\n\n### Component Spacing\nButton padding      → 12px vertical, 24px horizontal\nCard padding        → 16px\nList item padding   → 16px horizontal, 12px vertical\nSection spacing     → 24px-32px\nScreen edge margin  → 16px (phones), 24px (tablets)\n\n### Touch Target Spacing\nMinimum gap between interactive elements: 8px\nRecommended gap: 12-16px\n```\n\n---\n\n## Platform Guidelines\n\n### iOS Human Interface Guidelines\n\n```markdown\n## iOS Design Principles\n\n### Core Principles\n1. Clarity    → Text legible, icons precise, purpose obvious\n2. Deference  → UI helps understanding, not competing with content\n3. Depth      → Visual layers and realistic motion convey hierarchy\n\n### Navigation Patterns\n- Tab Bar (bottom) → 3-5 primary destinations\n- Navigation Bar (top) → Title, back button, actions\n- Modal sheets → Temporary focused tasks\n- Popovers (iPad) → Contextual options\n\n### 2025 Updates: Liquid Glass\n- Translucent materials for controls\n- Floating navigation elements\n- Dynamic depth and hierarchy\n- Background blur effects\n\n### Safe Areas\n- Top: Status bar + Dynamic Island/Notch\n- Bottom: Home indicator (34pt on Face ID devices)\n- Use safeAreaInsets for proper content placement\n\n### Standard Dimensions\n- Navigation bar height: 44pt (96pt with large title)\n- Tab bar height: 49pt (83pt on Face ID devices)\n- Toolbar height: 44pt\n```\n\n### Android Material Design 3\n\n```markdown\n## Material Design 3 Principles\n\n### Core Concepts\n1. Material You    → Personal, adaptive, dynamic color\n2. Expressiveness  → Emotional connection through design\n3. Accessibility   → Inclusive design for all users\n\n### Navigation Patterns\n- Bottom Navigation → 3-5 primary destinations\n- Navigation Drawer → 5+ destinations or secondary nav\n- Navigation Rail → Tablets and large screens\n- Top App Bar → Title, navigation, actions\n\n### Material 3 Expressive (2025)\n- Dynamic color from user wallpaper\n- Springy, physics-based motion\n- Bolder, more expressive typography\n- Rounded, approachable shapes\n\n### Component Shapes\n- Extra Small: 4dp\n- Small: 8dp\n- Medium: 12dp\n- Large: 16dp\n- Extra Large: 28dp\n- Full: 50% (pills/circles)\n\n### Standard Dimensions\n- App bar height: 64dp\n- Bottom navigation height: 80dp\n- FAB size: 56dp (standard), 40dp (small), 96dp (large)\n```\n\n---\n\n## 2025 Design Trends\n\n### AI-Driven Personalization\n\n```markdown\n## Adaptive UI Patterns\n\n### Personalization Strategies\n- Content recommendations based on behavior\n- Adaptive UI layouts based on usage patterns\n- Smart defaults and predictive actions\n- Contextual feature suggestions\n\n### Implementation Guidelines\n- Always provide manual override options\n- Explain why content is recommended\n- Respect user privacy preferences\n- Gradual personalization (don't overwhelm new users)\n```\n\n### Dark Mode Excellence\n\n```markdown\n## Dark Mode Best Practices\n\n### Color Adaptation\nLight Mode          →    Dark Mode\nWhite (#FFFFFF)     →    Dark gray (#121212)\nBlack (#000000)     →    White (#FFFFFF)\nPrimary (vibrant)   →    Primary (desaturated)\nShadows             →    Subtle shadows or none\n\n### Surface Elevation (Material 3)\nElevation 0  → #121212\nElevation 1  → #1E1E1E (+ 5% white overlay)\nElevation 2  → #232323 (+ 7% white overlay)\nElevation 3  → #272727 (+ 8% white overlay)\nElevation 4  → #2C2C2C (+ 9% white overlay)\nElevation 5  → #323232 (+ 11% white overlay)\n\n### Recommendations\n- Auto-switch based on system setting\n- Separate color tokens for light/dark\n- Test contrast in both modes\n- Consider OLED optimization (true blacks)\n```\n\n### Microinteractions\n\n```markdown\n## Meaningful Motion\n\n### Types of Microinteractions\n- Feedback → Button press, form submission\n- State → Loading, success, error\n- Guidance → Onboarding hints, tooltips\n- Delight → Celebration animations, easter eggs\n\n### Motion Principles\n- Duration: 200-500ms for most interactions\n- Easing: Use natural easing curves\n- Purpose: Every animation should have a reason\n- Performance: Use hardware-accelerated properties\n\n### 2025 Trends\n- Springy, physics-based animations\n- Morphing transitions between states\n- Gesture-driven interactions\n- Reduced motion support for accessibility\n```\n\n### Glassmorphism & Neumorphism\n\n```markdown\n## Modern Visual Styles\n\n### Glassmorphism\nProperties:\n- Background blur (backdrop-filter: blur)\n- Transparency (10-40% opacity)\n- Subtle border (1px white at 20% opacity)\n- Soft shadow\n\nUse Cases:\n- Overlays and modals\n- Cards on image backgrounds\n- Navigation bars (iOS Liquid Glass)\n\nCaution:\n- Ensure text readability\n- Consider performance impact\n- Provide fallback for older devices\n\n### Neumorphism (Soft UI)\nProperties:\n- Soft shadows (light and dark)\n- Subtle elevation effect\n- Muted color palette\n\nUse Cases:\n- Toggle switches\n- Input fields\n- Cards\n\nCaution:\n- Often fails accessibility contrast tests\n- Use sparingly, not as primary style\n- Always test with actual content\n```\n\n---\n\n\n## Extended Reference\n\nDetailed material starting at `## Accessibility Checklist` has been moved to [`reference/extended.md`](reference/extended.md) to keep this skill concise.
