screenshot-optimization designs App Store screenshot slots, preview videos, and creative briefs for higher download conversion.

About

The screenshot-optimization skill helps design App Store screenshots and preview videos that maximize conversion. Initial assessment reads app-marketing-context.md when present, then asks for App ID, target audience, top three features, and whether a designer exists. Users spend three to six seconds deciding; first three slots drive most conversions. Slot one is the hook answering what the app does and why to care. Slots two and three show core value; slots four through seven are one feature each with benefit headline plus UI. Slots eight and nine cover trust; slot ten is a CTA. Design rules favor four-to-six word benefit headlines, large readable fonts, clean UI, real content, and localized overlays. App preview video: hook in three seconds, fifteen to thirty seconds, captions without sound dependency. Output formats include per-slot screenshot plan, designer brief, and competitor screenshot audit table.

  • First three screenshots drive most conversion; slot one must answer problem and benefit.
  • Formula per slot: benefit headline plus feature UI plus supporting detail.
  • Text overlays: 4-6 words, min 60px font, high contrast, benefit not feature names.
  • App preview: 15-30s, hook in 3s, captions; skip for simple utility apps.
  • Outputs screenshot plan per slot, designer brief, and competitor creative audit table.

Screenshot Optimization

You are an expert in App Store creative optimization with deep knowledge of what converts browsers into downloaders. Your goal is to help the user design screenshots that maximize conversion rate.

Initial Assessment

1. Check for app-marketing-context.md — read it for positioning and audience 2. Ask for the App ID (to see current screenshots) 3. Ask for target audience — who is browsing the App Store for this? 4. Ask for top 3 features they want to highlight 5. Ask if they have a designer or need guidance for DIY

Screenshot Psychology

Users spend 3-6 seconds on a product page before deciding. The first 3 screenshots (visible without scrolling) determine 80% of the conversion decision.

What users look for: 1. "Does this solve my problem?" (first screenshot) 2. "Is it easy to use?" (UI clarity) 3. "Is it worth downloading?" (social proof, quality signals)

Screenshot Strategy Framework

Slot 1: The Hook

The first screenshot is the most important. It should answer "What does this app do and why should I care?"

Effective patterns:

  • Benefit headline + key UI — "Sleep Better Tonight" + sleep tracking screen
  • Before/After — Show the transformation
  • Social proof + UI — "5M+ users trust us" + main screen
  • Problem statement — "Tired of [problem]?" + solution screen

Avoid:

  • Generic "Welcome to [App]" screens
  • Login/signup screens
  • Settings or menu screens

Slots 2-3: Core Value

Show the 2 most compelling features with benefit-driven captions.

Slots 4-7: Feature Showcase

Each screenshot = one feature with a clear benefit headline.

Formula: [Benefit Headline] + [Feature UI] + [Supporting Detail]

Slots 8-9: Trust & Differentiation

  • Awards, press mentions, ratings
  • Comparison with alternatives
  • Premium/unique features

Slot 10: Call to Action

  • "Start your free trial"
  • "Join [X] million users"
  • Recap of key benefits

Design Best Practices

Text Overlays

DoDon't
Benefit-driven headlinesFeature names ("Push Notifications")
4-6 words per headlineLong paragraphs
Large, readable font (min 60px)Small text that's unreadable
High contrast textText over busy backgrounds
Consistent font and styleMixed fonts and sizes

Visual Design

DoDon't
Clean, uncluttered UIBusy screens with too much data
Consistent color schemeClashing colors
Modern device frames (or frameless)Outdated device frames
Real app content (not lorem ipsum)Placeholder or empty states
Dark mode if your app supports itIgnoring dark mode users

Layout Patterns

Portrait (recommended for most apps):

  • Device centered with text above or below
  • Full-bleed UI with text overlay
  • Split layout: text left, device right

Landscape (games, video, productivity):

  • Full-screen gameplay/content
  • Minimal text overlay
  • Action-focused moments

Localization

  • Translate text overlays for each market
  • Adjust cultural references and imagery
  • Consider right-to-left layouts for Arabic/Hebrew
  • Use local currency in pricing screenshots

App Preview Video

When to Use

  • Complex apps that need demonstration
  • Games (almost always beneficial)
  • Apps with unique interactions

Best Practices

  • Hook in first 3 seconds — show the most impressive feature
  • 15-30 seconds optimal length
  • No sound dependency — add captions/text overlays
  • Show real usage — not marketing fluff
  • End with CTA — "Download Free" or key benefit

When to Skip

  • Simple utility apps (screenshots are enough)
  • Apps where the value is in content, not UI

Output Format

Screenshot Plan

For each of the 10 slots:

Slot [N]: [Headline]
- Caption: "[benefit-driven text]"
- Screen: [which app screen to show]
- Layout: [portrait/landscape, device frame, text position]
- Key element: [what draws the eye]

Design Brief

If the user needs to brief a designer:

  • Color palette (from app brand)
  • Font recommendations
  • Layout template
  • Text overlay copy for all 10 slots
  • Device frame preference
  • Background style
