Icons for universal iOS apps

App Store Icon

  • 512×512 (scaled down to 175×175 for display in the store)

Application Icon

  • 114×114 (iPhone 4)
  • 57×57 (older iPhones)
  • 72×72 (iPad)

Spotlight Search Results and Settings Icon

  • 58×58 (iPhone 4)
  • 50×50 (Spotlight results for iPad)
  • 29×29 (settings for iPad and older iPhones)

Document Icon

This is a new icon type in iOS 4. It’s used if your app creates a custom document type. The iPad uses the document icon in two different sizes.

  • 320×320 (iPad)
  • 64×64 (iPad)
  • 44×58 (iPhone 4)
  • 22×29 (older iPhones)

For every image in your app, add a second version that’s twice the size, adding @2x to the name. For a low-resolution image named image.png you would add a second file named image@2x.png. The new image will be picked up automatically by iPhone 4. Everywhere your code requests image.png, image@2x.png will be used instead.
