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):

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/
├── Appfile
├── Deliverfile
├── metadata/
│   ├── copyright.txt
│   ├── primary_category.txt
│   ├── secondary_category.txt
│   ├── en-US/
│   │   ├── name.txt
│   │   ├── subtitle.txt
│   │   ├── description.txt
│   │   ├── keywords.txt
│   │   ├── promotional_text.txt
│   │   ├── release_notes.txt
│   │   ├── privacy_url.txt
│   │   ├── support_url.txt
│   │   └── marketing_url.txt
│   └── review_information/
│       ├── demo_password.txt
│       ├── demo_user.txt
│       ├── email_address.txt
│       ├── first_name.txt
│       ├── last_name.txt
│       ├── notes.txt
│       └── phone_number.txt
└── screenshots/
    └── en-US/
        ├── iphone_6.9_inch/
        │   ├── 1_feature_one.png
        │   ├── 2_feature_two.png
        │   └── ...
        └── ipad_13_inch/
            ├── 1_feature_one.png
            └── ...

Use scripts/​init_fastlane_structure.py to generate this structure.
