The concept of app icons was pioneered by the original iPhone in 2007, where Steve Jobs insisted that every app should have a beautiful, instantly recognizable icon.
Apple's design guidelines specify exact corner radius formulas: for iOS icons, the corner radius should be approximately 22.37% of the icon's width.
Android initially used completely square icons, but Material Design introduced adaptive icons in 2017, allowing for more dynamic and consistent shapes across different launchers.
Fun fact: The most expensive app icon design cost over $300,000 - it was for a luxury mobile app targeting ultra-high-net-worth individuals.
Great app icons follow the principle of immediate recognition - users should understand what your app does within 50 milliseconds of seeing the icon.
Research shows that icons with high contrast and simple geometric shapes perform 40% better in app store conversion rates.
The golden ratio (1.618:1) appears frequently in successful app icon designs, particularly in the relationship between the main element and negative space.
Color psychology plays a crucial role: blue icons are associated with trust and productivity, while red creates urgency, and green suggests growth or finance.
Most successful apps A/B test dozens of icon variations before settling on their final design, with conversion rate improvements of up to 30% from icon optimization alone.
Our tool generates all the required icon sizes for both iOS and Android platforms. For iOS, this includes sizes from 20x20 to 1024x1024 pixels, and for Android, sizes from 36x36 to 512x512 pixels across different density buckets (mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi).
iOS automatically applies rounded corners to app icons, but it's best practice to design with this in mind. Android also uses rounded corners in many launchers. Having proper rounded corners ensures your icon looks professional and consistent across all platforms.
