iOS App Icon Generator

Create beautiful, production-ready iOS app icons through a two-phase creative process.

Phase 1: Visual Philosophy

Before drawing anything, develop a 2-3 paragraph Icon Philosophy that articulates:

Core concept: What single idea or feeling should the icon convey?
Visual metaphor: What shape, object, or abstraction represents the app's purpose?
Color psychology: What palette evokes the right emotional response?
Silhouette test: Will it be recognizable as a tiny black shape?

Write this philosophy out. It guides every design decision.

Design Principles

Icons that work follow these rules:

Simplicity: One focal element. No more than 2-3 colors. No text (illegible at small sizes).
Distinctiveness: Must stand out in a grid of 30 other icons. Avoid generic symbols (gears, checkmarks, clouds).
Scalability: The 16x16 notification icon must read as clearly as the 1024x1024 App Store version.
No photography: Apple's guidelines discourage photos. Use illustration, geometry, or abstract forms.
Optical balance: Center of visual weight, not geometric center. Curves feel heavier than straight lines.

Phase 2: Icon Generation

Generate the icon as a self-contained HTML file with embedded SVG that:

Renders the icon design at 1024x1024 (the master size)
Includes iOS-style rounded corners (superellipse, not CSS border-radius)
Shows a preview grid of all sizes to verify readability
Provides a download mechanism for each size

Required Sizes

Generate all iOS app icon sizes:

Size	Purpose
1024x1024	App Store
180x180	iPhone (@3x)
167x167	iPad Pro (@2x)
152x152	iPad (@2x)
120x120	iPhone (@2x)
87x87	Spotlight (@3x)
80x80	Spotlight (@2x)
76x76	iPad (@1x)
60x60	iPhone (@1x)
58x58	Settings (@2x)
40x40	Spotlight (@1x)
29x29	Settings (@1x)
20x20	Notification (@1x)

HTML Artifact Structure

<!DOCTYPE html>
<html>
<head>
  <title>App Icon: [Name]</title>
  <style>
    /* Dark interface, icon grid layout, download buttons */
  </style>
</head>
<body>
  <!-- Philosophy statement -->
  <!-- Master SVG at 1024x1024 -->
  <!-- Preview grid showing all sizes -->
  <!-- Download buttons (use canvas to convert SVG → PNG) -->
  <script>
    // SVG → Canvas → PNG download logic
  </script>
</body>
</html>

SVG Guidelines

Use viewBox="0 0 1024 1024" for the master
Apply the iOS squircle mask (superellipse with n≈5)
Use gradients sparingly but effectively
Ensure googd stroke widths scale proportionally
Test: zoom browser to 25% - is the icon still clear?

iOS Squircle Mask

The iOS icon shape is NOT a rounded rectangle. Use this superellipse path or approximate with:

<clipPath id="ios-squircle">
  <path d="M512,1024 C252,1024 0,772 0,512 C0,252 252,0 512,0 C772,0 1024,252 1024,512 C1024,772 772,1024 512,1024 Z" />
</clipPath>

Or generate programmatically with the superellipse formula: |x/a|^n + |y/b|^n = 1 where n ≈ 5.

Process

Ask about the app's purpose, name, and any existing brand colors
Write the Icon Philosophy
Describe 2-3 concept directions with rationale
Get user approval on a direction
Generate the HTML artifact with full icon set
Iterate based on feedback

Quality Bar

The output should look like it belongs on a top-10 App Store chart. Every icon in that grid was crafted by a professional designer - yours should be indistinguishable from theirs.

Avoid:

Glossy/skeuomorphic styles (outdated since iOS 7)
Thin hairline details (disappear at small sizes)
Overly complex illustrations
Generic clip-art aesthetics
Centered-circle-on-gradient laziness
