```

Step 1: Generate App Metadata

Gather information from user about their app:

  • App name and bundle identifier
  • Core functionality (what problem it solves)
  • Target audience
  • Key features (3-5 main features)
  • Competitor apps (for positioning)

Output Files

Generate these localized text files (start with en-US):

| File | Max Length | Purpose |

|------|------------|---------|

| name.txt | 30 chars | App name on App Store |

| subtitle.txt | 30 chars | Brief tagline below app name |

| description.txt | 4000 chars | Full app description |

| promotional_text.txt | 170 chars | Updatable promo text (top of description) |

| keywords.txt | 100 chars | Comma-separated, no spaces after commas |

| release_notes.txt | 4000 chars | What's new in this version |

| support_url.txt | URL | Support page link |

| marketing_url.txt | URL | Marketing page link |

| privacy_url.txt | URL | Privacy policy link (REQUIRED) |

Writing Guidelines

Description structure:

  1. Opening hook (1-2 sentences) - immediately convey value
  2. Key features with bullet points (use ● not -)
  3. Social proof if available
  4. Call to action

Keywords strategy:

  • Use all 100 characters
  • No duplicates of words in app name
  • Include common misspellings
  • Mix head terms and long-tail
  • Separate with commas, no spaces

Step 2: Create App Screenshots

Required Dimensions (2024/2025)

iPhone (Required: ONE of these):

  • 6.9" display: 1320 x 2868 px (portrait) / 2868 x 1320 px (landscape) - iPhone 16 Pro Max
  • 6.5" display: 1242 x 2688 px (portrait) / 2688 x 1242 px (landscape) - fallback

iPad (Required if app runs on iPad):

  • 13" display: 2064 x 2752 px (portrait) / 2752 x 2064 px (landscape)

Optional (auto-scaled from above):

  • All other iPhone sizes scale from 6.9"/6.5"
  • All other iPad sizes scale from 13"

Screenshot Design Process

  1. Identify key screens - Focus on 5-10 most compelling features
  2. Create device mockups - Use scripts/generate_screenshot_mockup.py
  3. Add marketing text - Short, benefit-focused headlines
  4. Maintain consistency - Same style, colors, typography across all

Screenshot Content Guidelines

  • First 3 screenshots are critical (visible in search results)
  • Show actual app UI (Apple rejects misleading screenshots)
  • Text overlays: 6-8 words max per screenshot
  • Include device frame for professional look
  • Use app's brand colors for backgrounds

See references/screenshot-specs.md for detailed dimensions and file naming.

Step 3: Generate App Icon

Icon Specifications

App Store icon: 1024 x 1024 px (PNG, no transparency, no rounded corners)

Apple applies corner radius automatically. Submit square icon.

Icon Design Principles

  • Simple, recognizable silhouette
  • Limited color palette (2-3 colors)
  • No text (illegible at small sizes)
  • Avoid photos (don't scale well)
  • Test at 29x29 px for clarity

Use scripts/generate_app_icon.py to create icon or provide concept for AI generation.

Step 4: Set Up Fastlane Structure

Create this folder structure for fastlane deliver:

```

fastlane/

β”œβ”€β”€ Appfile

β”œβ”€β”€ Deliverfile

β”œβ”€β”€ metadata/

β”‚ β”œβ”€β”€ copyright.txt

β”‚ β”œβ”€β”€ primary_category.txt

β”‚ β”œβ”€β”€ secondary_category.txt

β”‚ β”œβ”€β”€ en-US/

β”‚ β”‚ β”œβ”€β”€ name.txt

β”‚ β”‚ β”œβ”€β”€ subtitle.txt

β”‚ β”‚ β”œβ”€β”€ description.txt

β”‚ β”‚ β”œβ”€β”€ keywords.txt

β”‚ β”‚ β”œβ”€β”€ promotional_text.txt

β”‚ β”‚ β”œβ”€β”€ release_notes.txt

β”‚ β”‚ β”œβ”€β”€ privacy_url.txt

β”‚ β”‚ β”œβ”€β”€ support_url.txt

β”‚ β”‚ └── marketing_url.txt

β”‚ └── review_information/

β”‚ β”œβ”€β”€ demo_password.txt

β”‚ β”œβ”€β”€ demo_user.txt

β”‚ β”œβ”€β”€ email_address.txt

β”‚ β”œβ”€β”€ first_name.txt

β”‚ β”œβ”€β”€ last_name.txt

β”‚ β”œβ”€β”€ notes.txt

β”‚ └── phone_number.txt

└── screenshots/

└── en-US/

β”œβ”€β”€ iphone_6.9_inch/

β”‚ β”œβ”€β”€ 1_feature_one.png

β”‚ β”œβ”€β”€ 2_feature_two.png

β”‚ └── ...

└── ipad_13_inch/

β”œβ”€β”€ 1_feature_one.png

└── ...

```

Use scripts/init_fastlane_structure.py to generate this structure.
