Why it matters
Your icon is the first thing users see
Before they read your name, before they see your screenshots — they see your icon. It appears on the home screen, in search results, in notifications, and in the App Store listing. A pixel-perfect icon at every size is non-negotiable.
Icon knowledge
Things every app developer should know
1024px
Required minimum
Apple requires exactly 1024×1024px with no transparency for the App Store.
108dp
Android adaptive canvas
Android adaptive icons use 108dp with a 72dp safe zone. The OS masks the rest.
1999
Year of the favicon
The name "favicon" is short for "favorite icon" — coined with Internet Explorer 5.
50+
Views per day
Your app icon appears on screen over 50 times daily on the average user's phone.
22.37%
Corner radius
iOS uses a superellipse with a ~22.37% corner radius — not a simple rounded rect.
6.84M
Apps worldwide
There are 6.84 million apps across the App Store and Google Play combined.
