IPA and PKG files are essential formats for installing applications on Apple devices, with IPA used for iOS, iPadOS, and tvOS, and PKG for macOS. To install IPA files on an iPhone or iPad, a connection to a macOS computer is necessary, utilizing either Apple Configurator or Xcode. Unsigned IPA files cannot be installed unless the device is jailbroken, as Apple enforces strict controls on app installation to prevent tampering and piracy. PKG files are exclusive to macOS systems, and their installation is straightforward. While IPA and APP formats are interchangeable for iOS installations, they serve different purposes, with IPA containing metadata for App Store listings and APP being the raw application bundle. Remote IPA deployment across multiple devices can be streamlined using solutions like Esper, which offers comprehensive device management tools for enterprises.

The Apple Volume Purchase Program (VPP) allows organizations such as businesses and educational institutions to buy apps and books in bulk for Apple devices like iPhones, iPads, and Macs through their Apple Business Manager account, using VPP credit instead of a traditional credit card for increased security and predictability. While VPP facilitates the automated distribution of purchased apps and books across devices, it does not support in-app purchases or other content like music and movies, which require manual management or custom agreements with developers. VPP can be integrated with Mobile Device Management (MDM) solutions to streamline the assignment of licenses, though the credit must be manually replenished, and discounts are not provided beyond any existing Apple Education discounts. The program is primarily designed to ease the procurement process for educational and business environments, simplifying content distribution without incurring additional App Store commissions for custom enterprise solutions.

Web Clips on iOS, introduced with iOS 4 and now available on iPadOS and macOS, provide users with an app-like shortcut to web links without needing to open a browser each time. These customizable tools extend beyond simple web link access to include functionalities like quick communication with frequently used contacts, direct access to media and files, and navigation and app store links. Users can set Web Clips to open in various browsers and personalize them with custom icons and names. Organizations using Esper Mobile Device Management (MDM) can centrally manage Web Clips across devices, offering benefits like quick access to essential links, improved user experience, and security features such as non-removability for critical resources. These capabilities make Web Clips particularly valuable for managing large fleets of devices in sectors like retail, education, and enterprise, while reducing the need for additional app development.
