.ipa - iOS App Store Package

An .ipa file is an iPhone application archive file which stores an iPhone app. It is usually encrypted with Apple's FairPlay DRM technology. Each .ipa file is compressed with a binary for the ARM architecture and can only be installed on an iPhone, iPod Touch, or iPad. Files with the .ipa extension can be uncompressed by changing the extension to .zip and unzipping. .ipa files cannot be installed on the iPhone Simulator because they do not contain a binary for the x86 architecture.
