Apple informs developers of high resolution requirements for screenshots of their iPhone & iPod touch apps
Apple sent out an interesting email to developers today informing them of the need for high resolution screenshots for apps developed for the iPhone and iPod touch.
We would like to make you aware of the following:
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.
New Notification for Binaries Exceeding Cellular Network Download Size Limit
Admin and Technical users will now be notified if your resulting binary size for the App Store exceeds the cellular network download size limit of 20MB. Exceeding the limit requires your app to be downloaded over Wi-Fi. This information can help you determine if you want to resubmit your binary in order to reduce the size of your app.
The App Store Team
I don’t know if this is just a reminder to those developers with older apps in the App Store that they need to upgrade their screenshots, or a hint that there is something else coming down the pipe that developers should be aware of.
