WatchOS in the context of "IPadOS version history"

Apple Maps is a web mapping service developed by Apple. As the default map system of iOS, iPadOS, macOS, tvOS, visionOS, and watchOS, it provides directions and estimated times of arrival for driving, walking, cycling, and public transportation navigation. A "Flyover" mode shows certain urban centers and other places of interest in a 3D landscape composed of models of buildings and structures.

First released in 2012, Apple Maps replaced Google Maps as the default map system on Apple devices. At launch, it drew criticism from users and reviewers for incorrect directions, sparse data about public transportation, and various other bugs and errors. Apple has since further developed the software to address the issues raised by such criticism.

iOS (formerly iPhone OS) is a mobile operating system created and developed by Apple for its iPhone line of smartphones. It was unveiled in January 2007 alongside the first-generation iPhone, and was released in June 2007. Major versions of iOS are released annually; the current stable version, iOS 26, was released to the public on September 15, 2025.

Besides powering iPhone, iOS is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. iOS formerly also powered iPads until iPadOS was introduced in 2019 and the iPod Touch line of devices until its discontinuation. iOS is the world's second most widely installed mobile operating system, after Android. As of December 2023, Apple's App Store contains more than 3.8 million iOS mobile apps.

macOS (previously OS X and originally Mac OS X) is a proprietary Unix-based operating system, derived from OPENSTEP for Mach and FreeBSD, which has been marketed and developed by Apple since 2001. It is the current operating system for Apple's Mac computers. Within the market of desktop and laptop computers, it is the second most widely used desktop OS, after Microsoft Windows and ahead of all Linux distributions, including ChromeOS and SteamOS. As of 2025, the most recent release of macOS is macOS 26 Tahoe, the 22nd major version of macOS.

Mac OS X succeeded the classic Mac OS, the primary Macintosh operating system from 1984 to 2001. Its underlying architecture came from NeXT's NeXTSTEP, as a result of Apple's acquisition of NeXT, which also brought Steve Jobs back to Apple. The first desktop version, Mac OS X 10.0, was released on March 24, 2001. Mac OS X Leopard and all later versions of macOS, other than OS X Lion, are UNIX 03 certified. Each of Apple's other contemporary operating systems, including iOS, iPadOS, watchOS, tvOS, audioOS and visionOS, are derivatives of macOS. Throughout its history, macOS has supported three major processor architectures: the initial version supported PowerPC-based Macs only, with support for Intel-based Macs beginning with OS X Tiger 10.4.4 and support for ARM-based Apple silicon Macs beginning with macOS Big Sur. Support for PowerPC-based Macs was dropped with OS X Snow Leopard, and it was announced at the 2025 Worldwide Developers Conference that macOS Tahoe will be the last to support Intel-based Macs.

Siri (/ˈsɪri/ SEER-ee) is a virtual assistant and chatbot purchased, developed, and popularized by Apple Inc., which is included in the iOS, iPadOS, watchOS, macOS, Apple TV, audioOS, and visionOS operating systems. It uses voice queries, gesture based control, focus-tracking and a natural-language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of Internet services. With continued use, it adapts to users' individual language usages, searches, and preferences, returning individualized results.

Siri is a spin-off from a project developed by the SRI International Artificial Intelligence Center. Its speech recognition engine was provided by Nuance Communications, and it uses advanced machine learning technologies to function. Its original American, British, and Australian voice actors recorded their respective voices around 2005, unaware of the recordings' eventual usage. Siri was released as an app for iOS in February 2010. Two months later, Apple acquired it and integrated it into the iPhone 4s at its release on 4 October 2011, removing the separate app from the iOS App Store. Siri has since been an integral part of Apple's products, having been adapted into other hardware devices including newer iPhone models, iPad, iPod Touch, Mac, AirPods, Apple TV, HomePod, and Apple Vision Pro.

The following is a list of operating systems released by Apple Inc. As of 2025, there are six supported software platforms: iOS, iPadOS, watchOS, tvOS, macOS and visionOS.

Prior to the introduction of the Macintosh in early 1984, Apple had several operating systems for the Apple II series, Apple SOS for the Apple III series, and Lisa OS and MacWorks XL for the Apple Lisa series; those were introduced between 1977 and 1983.

VoiceOver is a screen reader built into Apple Inc.'s macOS, iOS, tvOS, watchOS, and iPod operating systems. By using VoiceOver, the user can access their Macintosh or iOS device based on spoken descriptions and, in the case of the Mac, the keyboard. The feature is designed to increase accessibility for blind and low-vision users, as well as for users with dyslexia.

The keyboard shortcut to activate VoiceOver is ⌘ Command+F5.

iOS (formerly iPhone OS) is a mobile operating system developed by Apple Inc. and was first released in June 2007 alongside the first generation iPhone. iPhone OS was renamed iOS following the release of the iPad starting with iOS 4. With iOS 13, Apple began offering a separate operating system, iPadOS, for the iPad. iOS is also the foundation of watchOS and tvOS, and shares some of its code with macOS. New iOS versions are released yearly, alongside new iPhone models. From the launch of the iPhone in 2007 until the launch of iPhone 4 in 2010, this occurred in June or July; since then, new major versions are usually released in September, with the exception of iOS 5, which released in October 2011. Since the launch of the iPhone in June 2007, there have been nineteen major versions of iOS, with the current major version being iOS 26 which was released on September 15, 2025.

The Worldwide Developers Conference (WWDC) is an information technology conference held annually by Apple Inc. The conference is currently held at Apple Park in California. The event is used to showcase new software and technologies in the macOS, iOS, iPadOS, watchOS, tvOS, and visionOS families as well as other Apple software; new hardware products are sometimes announced as well. WWDC is also an event hosted for third-party software developers that work on apps for iPhones, iPads, Macs, and other Apple devices. Attendees can participate in hands-on labs with Apple engineers and attend in-depth sessions covering a wide variety of topics.

The first WWDC was held in 1983, with the introduction of Apple Basic, but it was not until 2002 that Apple started using the conference as a major launchpad for new products. Beginning in 1987, WWDC was held in Santa Clara. After 15 years in nearby San Jose, the conference moved to San Francisco, where it eventually became Apple's primary media event of the year and regularly sold out. WWDC returned to San Jose 13 years later.
