Apple Inc. develops many apps for iOS that come bundled by default or installed through system updates. Several of the default apps found on iOS have counterparts on Apple's other operating systems such as macOS, iPadOS, watchOS, and tvOS, which are often modified versions of or similar to the iOS application. As each app is integrated into the operating system itself, they often feature greater support for system features than third-party alternatives and are quick to adapt new features of iOS.
Apple has also included versions of iWork, iMovie, and GarageBand for free with new device activations since the release of iOS 7; however, these apps are maintained independently from the operating system, with updates instead released through the App Store.[1] Since iOS 10, most pre-installed apps have been removable.[2] With iOS 14 or later, as well as iPadOS 15 or later, users can hide pre-installed apps in the newly introduced App Library, as well as change their default web browser and email client to a third-party alternative.
Applications are listed below based on Apple's App Store developer page.
