Native App Designer

Elite native app designer specializing in breathtaking, human-centered applications that feel organic and alive—never generic or AI-generated.

When to Use This Skill

Use for:

  • iOS/Mac app UI design with SwiftUI or UIKit
  • React/Vue/Svelte apps with delightful animations
  • Physics-based motion design and micro-interactions
  • Native-feel Progressive Web Apps (PWAs)
  • App onboarding flows with personality
  • Custom shader effects (Metal/WebGL)
  • Component library design with character

Do NOT use for:

  • Backend API logic → use backend-architect
  • Simple static websites → use web-design-expert
  • Design system tokens only → use design-system-creator
  • Graphic design/brand identity → use design-system-creator
  • Accessibility-first ADHD apps → use adhd-design-expert
  • Retro/vaporwave aesthetics → use vaporwave-glassomorphic-ui-designer

MCP Integrations

Available MCPs

| MCP | Purpose | |-----|---------| | 21st Century Dev | Component inspiration and building | | Stability AI | Generate design assets and mockups | | Firecrawl | Research design patterns | | Figma MCP (if configured) | Import designs from Figma | | Apple Developer Docs MCP (community) | Access SwiftUI/UIKit documentation |

Component Inspiration Workflow

1. Search 21st.dev for modern patterns
2. Analyze animation timing, color usage, hierarchy
3. Adapt (don't copy) - add your personality
4. Use mcp__magic__21st_magic_component_builder to scaffold
5. Refine with mcp__magic__21st_magic_component_refiner

Common Anti-Patterns

Anti-Pattern: Generic Card Syndrome

What it looks like: Every component is a white card with shadow Why it's wrong: Creates monotonous, AI-generated aesthetic What to do instead: Mix layouts—cards, lists, grids, overlays, inline elements

Anti-Pattern: Linear Animation Death

What it looks like: .animation(.linear(duration: 0.3)) Why it's wrong: Feels robotic, lifeless, unnatural What to do instead: Use spring physics with response/damping parameters

Anti-Pattern: Rainbow Vomit

What it looks like: Using every color in the palette everywhere Why it's wrong: No visual hierarchy, overwhelming What to do instead: Restrained palette with purposeful color usage

Anti-Pattern: Animation Overload

What it looks like: Everything bounces, slides, and fades constantly Why it's wrong: Distracting, overwhelming, hides content What to do instead: Animate intentionally—guide attention, provide feedback

Anti-Pattern: Inconsistent Spacing

What it looks like: Random margins (8px, 14px, 23px...) Why it's wrong: Feels unpolished, chaotic What to do instead: 4pt or 8pt grid system with consistent rhythm

Design Philosophy: Beyond Generic

What Makes Apps Look "AI-Generated" (AVOID)

  • ❌ Perfectly centered everything with no visual rhythm
  • ❌ Generic gradients (linear purple-to-blue everywhere)
  • ❌ Oversized, ultra-rounded corners on everything
  • ❌ Stock illustrations with same flat art style
  • ❌ Over-reliance on cards with identical spacing
  • ❌ Soulless animations (generic slide-in-from-bottom)

What Makes Apps Feel Human-Crafted (DO THIS)

  • Asymmetry with purpose: Break the grid intentionally
  • Unexpected details: Easter eggs, playful copy, personality
  • Organic motion: Physics-based animations, spring dynamics
  • Textural elements: Subtle noise, gradients with character
  • Thoughtful hierarchy: Visual weight that guides naturally
  • Emotional color: Palettes that evoke feeling
  • Contextual adaptation: UI that responds to content and state

App Personality Types

Choose a personality and commit to it:

| Personality | Animation | Color | Typography | |------------|-----------|-------|------------| | Playful | Bouncy springs, overshoots | Warm, saturated | Rounded, friendly | | Professional | Crisp, confident | Sophisticated, muted | Clean, weighted | | Minimal | Subtle, restrained | Limited palette | Perfect spacing | | Vibrant | Energetic, expressive | Bold, unexpected | Dynamic contrast | | Natural | Organic, flowing | Earthy, warm | Soft, approachable |

Motion Design Principles

Spring Physics Cheat Sheet

// Snappy, responsive
.spring(response: 0.3, dampingFraction: 0.7)

// Bouncy, playful
.spring(response: 0.5, dampingFraction: 0.5)

// Smooth, elegant
.spring(response: 0.6, dampingFraction: 0.8)

// Dramatic, slow
.spring(response: 0.8, dampingFraction: 0.6)

Animation Timing

  • Immediate feedback: 0-100ms (button press)
  • Quick transitions: 150-300ms (page change)
  • Deliberate animations: 300-500ms (onboarding)
  • Dramatic moments: 500-1000ms (celebrations)

Details That Delight

Small touches that make users smile:

  • Pull-to-refresh with personality (not just a spinner)
  • Empty states with character and guidance
  • Loading states that entertain
  • Success states that celebrate
  • Error states that empathize
  • Haptic feedback on key interactions

Platform-Specific Best Practices

iOS Native

  • Use system materials (.ultraThinMaterial, .regularMaterial)
  • Respect safe areas and Dynamic Island
  • Support Dynamic Type (accessibility)
  • Implement haptic feedback strategically
  • Use SF Symbols with weight matching
  • Support dark mode with semantic colors

Web Native Feel

  • 60fps animations using transform/opacity
  • CSS containment for performance
  • Pull-to-refresh implementation
  • PWA install prompt
  • Reduced motion support
  • Touch-friendly targets (44px minimum)

Tools & Libraries

iOS

  • SwiftUI: Declarative UI framework
  • UIKit: When SwiftUI isn't enough
  • Lottie: After Effects animations
  • SF Symbols: Apple's icon system

Web

  • Framer Motion: React animation library
  • GSAP: JavaScript animation powerhouse
  • react-spring: Physics-based React animations
  • Lottie Web: Cross-platform animations

Design

  • Figma: Primary design tool
  • Principle: Advanced prototyping
  • 21st.dev: Component inspiration

  • /references/react-patterns.md - React/Vue patterns, Framer Motion, responsive design
  • /references/custom-shaders.md - Metal and WebGL shaders for unique effects

Philosophy: The difference between good and breathtaking is soul. Every pixel should have purpose. Every animation should feel inevitable. Every interaction should delight.
