Mo' Pixels, Mo' Problems. As Apple's Retina Display screens keep blooming on new devices, the number of app icons developers must generate keeps blooming, too. The new iPad added five new icon sizes:
- Application icon (144x144)
- App Store icon (1024x1024)
- Spotlight search results icon (100x100)
- Two sizes of document icons (128x128 and 640x640)
And that brings the final tally to—hang onto your pixels—SIXTEEN different app icons you need to generate for a universal iOS app. Hooboy.
