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:
- Opening hook (1-2 sentences) - immediately convey value
- Key features with bullet points (use β not -)
- Social proof if available
- 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
- Identify key screens - Focus on 5-10 most compelling features
- Create device mockups - Use scripts/generate_screenshot_mockup.py
- Add marketing text - Short, benefit-focused headlines
- 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/
βββ Appfile
βββ Deliverfile
βββ metadata/
β βββ copyright.txt
β βββ primary_category.txt
β βββ secondary_category.txt
β βββ en-US/
β β βββ name.txt
β β βββ subtitle.txt
β β βββ description.txt
β β βββ keywords.txt
β β βββ promotional_text.txt
β β βββ release_notes.txt
β β βββ privacy_url.txt
β β βββ support_url.txt
β β βββ marketing_url.txt
β βββ review_information/
β βββ demo_password.txt
β βββ demo_user.txt
β βββ email_address.txt
β βββ first_name.txt
β βββ last_name.txt
β βββ notes.txt
β βββ phone_number.txt
βββ screenshots/
βββ en-US/
βββ iphone_6.9_inch/
β βββ 1_feature_one.png
β βββ 2_feature_two.png
β βββ ...
βββ ipad_13_inch/
βββ 1_feature_one.png
βββ ...
```
Use scripts/init_fastlane_structure.py to generate this structure.
