Best Practices

Screenshot Design

• Safe Zones: Keep important content away from edges - avoid top 20% for status bar area
• Text Hierarchy: Use large, readable headlines (minimum 40pt equivalent)
• Device Frames: Use current-generation device mockups (iPhone 15 Pro, Pixel 8)
• Contrast: Ensure text is readable over any background elements
• Consistency: Maintain same style, fonts, and color scheme across all screenshots

App Store Optimization

• First Screenshot: Make it your strongest - it's often the only one users see
• Feature Callouts: Highlight 1-2 key features per screenshot
• Localization: Translate all text for target markets, not just headlines
• Seasonal Updates: Refresh screenshots for major app updates

iPad Screenshots

• Landscape Option: iPad supports landscape screenshots for certain apps
• Utilize Space: Take advantage of larger canvas for more detailed UI
• Split View: Show multitasking capabilities if applicable

Mode Selection

Ask your users before generating:

"Do you want fast drafts for iteration, or final quality for submission?"

Mode	Best For	Speed	Quality
max	Final App Store submission, polished assets	Slower	Highest
eco	Quick drafts, A/B test variations, concept exploration	Faster	Good

Multi-Turn Screenshot Iteration

Use session_id to iterate on screenshot designs:

# Initial screenshot
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Create an iPhone App Store screenshot at 1320x2868 for a podcast app with episode list view"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "podcast-screenshot-v1"
  }'
