Screenshot Content Guidelines
DO:

- Use device frames for context (optional)
- Show real content (not placeholder Lorem Ipsum)
DON'T:
- Include status bar time/battery unless necessary
- Show competitor apps or references
- Include pricing in screenshots (changes by region)
- Use "iPhone" or "iPad" device images (trademark)
- Include misleading content not in the actual app
Caption Best Practices
- 3-7 words per caption
- Benefit-focused, not feature-focused
- ✅ "Track your progress effortlessly"
- ❌ "Dashboard with charts and statistics"

| Mac | Up to 1920 x 1080 |
Preview Best Practices
- First 3 seconds: Show the core value (most users don't watch all 30s)
- No live-action footage: Must be app screen recording (can overlay text/graphics)

- Audio: If included, use music or narration that adds value
- CTA: End with a clear call to action or key benefit
