Is iOS a subsidiary of Apple?

No. iOS is not a subsidiary or separate legal entity. It is a product line within Apple Inc., developed by the company's software engineering organization. All iOS intellectual property, revenue, and development decisions belong to Apple Inc. directly.

Is iOS publicly traded?

iOS itself is not separately traded. Apple Inc., the company that owns and develops iOS, trades on NASDAQ under the ticker AAPL. Investors seeking exposure to iOS can purchase Apple shares. Apple reported FY2025 revenue of $416.2 billion.

When was iOS founded?

iOS was first released on June 29, 2007, as iPhone OS 1.0, alongside the original iPhone. It was renamed iOS in June 2010 with the release of iOS 4. The operating system was created by an Apple team led by Scott Forstall under Steve Jobs.

iOS was developed internally at Apple. Steve Jobs directed the project, and Scott Forstall led the engineering team that built the operating system by adapting macOS for a mobile device. No external founders were involved. Apple Inc. itself was founded in 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne.

What is iOS's market position?

iOS is the second-largest mobile operating system globally by market share, holding approximately 30.86% as of June 2026 according to StatCounter. Android holds approximately 69.14%. iOS leads in the United States, Japan, Canada, and Australia, while Android dominates in most other markets.

Can other companies make iOS phones?

No. Apple does not license iOS to any third-party manufacturer. iOS runs exclusively on Apple hardware, including the iPhone and iPod Touch. This is a deliberate strategy that gives Apple full control over the hardware-software integration but limits iOS to devices Apple itself sells.

Has iOS had any major controversies?

Yes. The App Store commission structure has faced antitrust litigation from Epic Games and regulatory action under the EU Digital Markets Act. In 2012, the Apple Maps launch in iOS 6 was widely criticized for inaccuracies. In 2017, Apple confirmed it had throttled performance on older iPhones with degraded batteries, leading to lawsuits and settlements.

History of iOS

Founded: 2007
Founders: Apple Inc. (Steve Jobs, Scott Forstall)

Steve Jobs unveiled the iPhone on January 9, 2007, at Macworld in San Francisco. The device shipped on June 29, 2007, running what Apple initially called iPhone OS, though Jobs described it publicly as "OS X" at the launch. The operating system was built on a Unix-like foundation derived from macOS and Darwin, using the XNU kernel.

Development of iPhone OS involved an internal competition at Apple. A team led by Scott Forstall worked on shrinking macOS to fit a phone, while a team led by Tony Fadell worked on expanding the iPod into a phone. Jobs chose the Forstall approach, which gave the iPhone a full operating system capable of running third-party applications. This decision shaped the entire mobile app economy that followed.

The original iPhone OS 1.0 had no third-party app store. Apple shipped a small set of built-in apps including Safari, Mail, and iPod. Third-party developers were initially directed to build web applications for Safari. The App Store launched on July 10, 2008, with iPhone OS 2.0, opening the platform to native third-party applications. The store opened with approximately 500 apps.

Apple renamed the operating system from iPhone OS to iOS in June 2010 with the release of iOS 4, coinciding with the launch of the iPad. The name change reflected that the platform now powered multiple device categories. iPadOS later split off as a separate operating system in 2019 with iOS 13.

Major version milestones include iOS 3 (2009), which introduced copy and paste; iOS 4 (2010), which added multitasking and FaceTime; iOS 5 (2011), which introduced Siri and iCloud; iOS 7 (2013), a complete visual redesign led by Jony Ive; iOS 8 (2014), which introduced Continuity and HealthKit; iOS 11 (2017), which brought the iPad closer to a desktop model; and iOS 14 (2020), which added home screen widgets.

Apple Intelligence, the company's AI platform, launched with iOS 18 in September 2024. It introduced on-device machine learning features, a redesigned Siri, and integration with OpenAI's ChatGPT for certain queries. iOS 26, released on September 15, 2025, introduced a new visual design language called Liquid Glass, extending across iOS, iPadOS, macOS, watchOS, and tvOS simultaneously. iOS 26 also expanded Apple Intelligence with Live Translation and deeper visual intelligence features.

Scott Forstall led iOS development from its inception until his departure from Apple in 2012, following the controversy around Apple Maps in iOS 6. Craig Federighi assumed leadership of iOS engineering and has overseen the platform since.

As of July 2026, the App Store hosted approximately 2.49 million apps from over 1 million active publishers, according to 42matters. The App Store ecosystem facilitated over $1.4 trillion in developer billings and sales in 2025, according to an Analysis Group study commissioned by Apple.

iOS Recalls & Controversies

Epic Games v. Apple (2020-2025): Epic Games, developer of Fortnite, filed suit against Apple in August 2020, alleging that Apple's App Store commission structure and prohibition on alternative payment systems violated antitrust law. A federal judge ruled in September 2021 that Apple was not a monopoly but prohibited its anti-steering provisions. Both sides appealed. In 2025, the case continued through appeals, with courts examining whether Apple complied with the injunction. The litigation forced Apple to allow developers in the United States to link to external payment options.

EU Digital Markets Act (2024-2026): The European Commission designated Apple as a gatekeeper under the DMA in September 2023, covering the App Store and iOS. Apple was required to allow alternative app marketplaces and external payment links in the EU. In 2025, the Commission fined Apple 500 million euros for blocking developers from steering users to cheaper options outside the store. In July 2026, the EU General Court dismissed Apple's challenge to its gatekeeper designation. In August 2026, Apple overhauled its EU App Store fees, replacing the Core Technology Fee with a 5% Core Technology Commission, settling the dispute with the Commission.

Apple Maps Launch (2012): iOS 6, released in September 2012, replaced Google Maps with Apple's own Maps application. The launch was widely criticized for inaccurate data, missing features, and visual errors. Tim Cook issued a public apology, and Scott Forstall, the senior executive responsible for iOS, left Apple later that year. Apple Maps has since been substantially improved but the launch remains a notable failure in iOS history.

Battery Performance Throttling (2017): In late 2017, Apple confirmed that iOS 10.3 and later included power management features that slowed performance on older iPhones with degraded batteries to prevent unexpected shutdowns. Apple faced criticism for not disclosing the practice. The company offered discounted battery replacements and added a battery health feature in iOS 11.3. Apple paid settlements in multiple jurisdictions, including approximately $500 million in a US class action.

iOS Ownership: Pros & Cons

Advantages

+Full integration of hardware and software gives Apple tight control over performance, security, and user experience across the iPhone lineup
+The App Store generates substantial revenue through commissions, contributing to Apple's Services segment which reported $30.7 billion in Q3 FY2026
+Proprietary ownership means Apple captures all iOS-related revenue directly, with no licensing friction or manufacturer fragmentation
+Apple's financial scale supports sustained iOS development, with the company reporting $416.2 billion in FY2025 revenue

Considerations

-The closed model limits iOS to Apple hardware, ceding global device volume to Android which runs on dozens of manufacturers' phones
-App Store commission practices face ongoing antitrust litigation and regulatory action in the EU, United States, and other jurisdictions
-The EU Digital Markets Act has forced structural changes to iOS in Europe, including alternative app marketplaces and revised fee structures
-Battery throttling and Apple Maps controversies have created reputational damage that required executive-level responses and financial settlements
