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):

name.txt

subtitle.txt

description.txt

promotional_text.txt

keywords.txt

release_notes.txt

support_url.txt

marketing_url.txt

privacy_url.txt

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

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

Step 4: Set Up Fastlane Structure

Create this folder structure for

fastlane deliver

        └── ipad_13_inch/
            ├── 1_feature_one.png
            └── ...

Use

scripts/init_fastlane_structure.py
