Apple has issued a notice to all members of the iOS developer program, reports MacRumors, stating that all screenshots submitted for iPhone or iPod touch apps must now be optimized for Retina displays. Failure to include Retina screenshots will cause your App to be rejected by Apple’s approval process.
Required iPhone & iPod touch Screenshot Upgrade for Retina Display
When you create or update your apps in iTunes Connect, you must upload screenshots that are high-resolution. We require your screenshots as high-resolution images so that your app is optimized for the Retina display.
The requirements for high-resolution images are 960 x 640, 960 x 600, 640 x 960, or 640 x 920 pixels. Images must be at least 72 dpi, in the RGB color space, and the file must be .jpeg, .jpg, .tif, .tiff, or .png. You can update your screenshot files at any time in iTunes Connect.
Now that all current-gen iPhones and iPod touches include Retina displays, Apple is very aggressively pushing for developers to developer their apps for Retina displays. While apps can still be developed with support for previous models of the iPhone and iPod touch, Retina-optimized graphics are now a requirement.
Most developers have already updated their apps to support the higher resolution of Apple’s Retina displays. This latest push is nothing more than a decree that all apps must (in addition to possibly supporting older generation devices) be optimized for Apple’s latest devices. Retina displays have been included in all models of the iPhone and iPod touch since 2010.
