app-icon-optimization

App Icon Optimization is an App Store Optimization (ASO) guidance skill focused on designing, auditing, and A/B testing mobile app icons to maximize tap-through rate — the share of users who tap an app after seeing it in App Store search or browse. It frames the icon as the single most impactful store asset, since it is the first thing users see before the title, rating, or screenshots, and notes that a stronger icon can meaningfully lift tap-through with no other listing changes.

The skill provides concrete design principles: keep the mark simple and legible at small sizes (around 60x60), ensure strong color contrast in both light and dark App Store modes, study and differentiate from category visual norms, use a single recognizable mark describable in three words, and maintain brand consistency across splash screens, notifications, and marketing. It documents the required icon sizes across iPhone, iPad, Watch, and Android adaptive icons, and gives platform-specific A/B testing workflows using Apple App Store Connect Product Page Optimization and Google Play Store listing experiments, including traffic allocation, minimum run times, sample-size guidance, and which single variable to test at a time. It closes with a scored icon-audit rubric and a designer brief template.

It targets app developers, indie makers, product marketers, and ASO specialists who want a practical, checklist-driven reference for improving icon conversion. Use cases include auditing an existing icon, planning an icon refresh, briefing a designer, and structuring a rigorous icon A/B test on iOS or Android.
