Ad Hoc Distribution Authorizes a Limited Set of Devices to Run Your App
iOS developers enrolled in the Standard Program can also distribute an app outside of the App Store on up to 100 different devices for testing purposes only. To use ad hoc distribution, create an archive of your app, or have a teammate send you an iOS App Store Package (.ipa) of the archived app.
You distribute your app by providing the .ipa file for users to install on their devices. Because you select a valid ad hoc provisioning profile to archive the app, users don’t need to install the profile on their device, only the .ipa file. Users can use iTunes to install the app on their devices. If users want to use Xcode to install the app on their device, share the archive as an .xcarchive file package.
In-House Distribution Allows Companies to Distribute Apps Internally
iOS developers enrolled in the Enterprise Program can distribute in-house without identifying individual devices or using the App Store. To distribute your app in-house, create an archive of your app, or have a teammate send you an archived app. Distribute your internal app using your company’s authorized software distribution mechanism. Because the app file can be installed on any iOS device, make sure you protect the distribution of this file. Members of your company can use iTunes, iPhone Configuration Utility, or Xcode to install the app on their devices.
