App Store Screenshot Design: Best Practices That Drive Downloads

First Impressions in the App Store

Apple reports that 70% of visitors leave without tapping past the initial view. Your first three screenshots must instantly communicate your core value. The most effective answer one question: "What will this app do for me?" Benefits over features, always.

Screenshot Sizing for Every Device

Apple App Store

iPhone: 1290 x 2796 pixels (6.7-inch) and 1284 x 2778 pixels (6.5-inch). iPad: 2048 x 2732 pixels. Up to 10 screenshots per device class, per localization.

Google Play

Minimum 2 screenshots, up to 8. Recommended: 1080 x 1920 pixels for phones. ASOGenie generates correctly sized, localized variants for every device automatically.

The Psychology of Screenshot Design

Users spend an average of 7 seconds evaluating a listing. Use clear visual hierarchy: bold headline at top, device frame in center, subtle background. High contrast between text and background. Consistent color palette and typography across all screenshots builds trust. Include social proof like "Trusted by 1 Million Users" in later screenshots.
