How to Fix Your App Store Screenshots

Screenshots are the single highest-impact conversion lever in ASO. Bad screenshots (raw app screens, no context) convert at 20-30% of well-designed ones. Good screenshots tell a story across the visible slots, lead with the strongest value proposition, use captions, and adapt per locale. See the App Audit hub for the full ASO programme.

1. Visible slots per store

App Store (iOS):
  - Up to 10 screenshots per device size
  - First 3 visible without scroll (most important)
  - 6.7" (iPhone Pro Max) is reference; other sizes auto-scaled
  - Portrait or landscape (consistency within app)

Google Play:
  - Up to 8 screenshots
  - First 2-3 visible in listing preview
  - Phone, 7" tablet, 10" tablet versions

2. The story structure

Slot 1: HEADLINE BENEFIT
        Strongest value prop, brief caption
        "Track every lead automatically"

Slot 2: KEY FEATURE 1
        Specific capability with caption
        "AI prioritises hot prospects"

Slot 3: KEY FEATURE 2  
        Second capability
        "Drag and drop pipeline"

Slot 4-6: SECONDARY FEATURES
        Other capabilities, social proof

Slot 7-10: TRUST & DEPTH
        Awards, reviews, integrations, security

3. Caption-led design

Raw screenshots without captions convert poorly — users don't decode app UI in 1-2 seconds. Captions explain the value:

Bad:    [pure app screenshot]
Good:   "TRACK EVERY LEAD" [headline]
        [app screenshot showing leads]
        "Never lose a prospect again" [subhead]

Caption layout:
  - Headline: 4-6 words, biggest text
  - Subhead: 8-12 words, supporting
  - Use brand colours
  - Background colour matching brand
  - 60-70% screen for caption, 30-40% for screenshot

4. Localisation matters here too

Each App Store / Play locale gets its own screenshots. Don't just translate captions — adjust visuals for cultural context. Numeric formats, currency symbols, character sets all matter:

US:    "$29/month"   English caption
UK:    "£24/month"   English caption (different price possibly)
DE:    "29€/Monat"   German caption
JP:    "¥3,200/月"   Japanese caption + JP-localised app UI in screenshot

5. Social proof in screenshots

Slots 4-6 often include:

• Star ratings ("4.8/5 from 12,000 reviews")
• Awards (App Store Editor's Choice, etc.)
• Press quotes ("Best CRM of 2025 — TechCrunch")
• Customer logos (B2B apps)
• User testimonials with photos

6. A/B test

App Store Connect (iOS 15+) Custom Product Pages allow split tests. Google Play Store Listing experiments too. Test:

• Slot 1 caption variation (headline alternatives)
• Caption colour / contrast
• Portrait vs landscape
• Order of slots 2-4
• Inclusion of social proof early vs late
