Drop a screenshot
PNG or JPG of your app screen
Renders fully in your browser at the exact App Store dimensions. Use the iPhone 6.5″ preset to satisfy Apple's legacy required size, then upload the same image across the other slots.
Splash screens
One source image now powers your splash screen too.
- iOS uses a launch storyboard or, with Expo, the
expo-splash-screenconfig — a single 1242 × 2436 image plus a background color. - Android 12+ uses the system splash API — a single 1024 × 1024 icon (the same one you uploaded above) on a background color, with optional branding image.
- Use the same square icon you generated above. Add a solid or gradient background in your app config to match your brand.
Recommended Expo splash config
"plugins": [
["expo-splash-screen", {
"image": "./assets/icon.png",
"imageWidth": 200,
"resizeMode": "contain",
"backgroundColor": "#ffffff"
}]
]Newly apps generate this config automatically when you set your brand color.

Design tips
5 tips for an icon that survives the home screen.
One color, one shape
The strongest icons in the App Store top 50 use one primary color and one bold geometric shape. Save the gradient hero art for your screenshots.
Test at 60 px
The Spotlight search icon is 87 px on the highest-density iPhone. If your icon isn't legible at 60 px on a desktop monitor, it won't be on a phone.
Avoid words
Apple's Human Interface Guidelines explicitly recommend against text in icons. The system already shows the app name underneath.
Square first, mask second
Always upload a true square. iOS, Android, and PWA all apply their own mask. Pre-rounding the corners produces an ugly inset square inside the system mask.
