If you're shipping an app, your icon is doing more conversion work than you think. It's the first thing users see in search results, before title or screenshots, and a strong icon can lift tap-through rate by 20-40% with zero other changes. This walks you through designing for 60x60pt legibility, contrast against App Store backgrounds in both light and dark mode, and category differentiation tactics. The A/B testing section is practical: it covers Product Page Optimization on iOS and Store Listing Experiments on Android, what variables to isolate (color, mark style, character vs abstract), and how to read significance. The designer brief template alone will save you a revision cycle.
