A compelling app icon serves as your app's first impression across store listings, search results, and category rankings. Creating an icon that meets platform requirements ensures consistent display quality across all store locations.

Technical requirements for app icons:

• App Store: 1024x1024px in PNG format, with no transparency or alpha channels.^[[1]]
• Google Play Store: 512x512px in PNG format, with no transparency.^[[2]]
• Both platforms require square icons with 90-degree corners before system masking is applied.

Design considerations for both stores:

• Use bold, simple designs that remain recognizable in smaller sizes.
• Avoid text unless it's an essential part of your brand mark.
• Test your icon against light and dark backgrounds.
• Ensure the design maintains a visual hierarchy when scaled down.

Each platform applies its own masking and effects to your icon automatically. Your original asset should fill the entire square canvas, letting the platform handle corner rounding and other stylistic treatments.
