A New Phase of Apple App Store Regulation
Apple app store regulation refers to the growing set of competition and interoperability rules that limit Apple’s control over how apps are distributed on iOS and how in‑app payments are processed, forcing the company to support third-party app stores, alternative payment systems, and equal technical access for rivals that compete with Apple’s own services. Together, these policies challenge Apple’s long-standing preference for a single, tightly controlled App Store and its proprietary payment tools. What once was a unified global model is starting to fragment into jurisdiction-specific rulesets. Developers now face different distribution and monetisation options depending on where users live, while regulators test how far they can push a dominant platform to open up without undermining security or user experience. Apple is being compelled to redesign the boundaries of its ecosystem almost market by market.
Italian DMA Probe: Interoperability Tests Apple’s Walled Garden
In one key jurisdiction, the focus is interoperability rather than app store structure itself. The competition authority has opened a fresh investigation into Apple under the EU’s Digital Markets Act (DMA), only months after imposing a penalty of more than €98.6m for abusing a “super-dominant position” in app distribution with its App Store. According to AGCM, Apple holds more than 40pc of the mobile operating system market share in Europe and may be denying third-party cloud providers the same access to iOS and iPadOS features that iCloud enjoys. For example, it appears alternative cloud storage services cannot use system-level full-device backup functionality. Under DMA compliance requirements, designated gatekeepers must offer “free and effective interoperability” to rivals. Apple has already faced a €500m fine for limiting developers’ ability to inform users about offers outside the App Store, signalling that authorities will penalise even subtle self‑preferencing.
Brazil: Third-Party App Stores and Alternative Payment Systems
In another major market, regulators have gone straight at Apple’s distribution and billing model. Following a three-year investigation triggered by a complaint from Mercado Libre, Apple has agreed with local antitrust authorities to allow developers to distribute iOS apps via third-party marketplaces and to process transactions outside its ecosystem. These third-party app stores must be approved and meet ongoing requirements, but their very existence breaks Apple’s long-standing single-store rule. Apple will also permit alternative payment systems inside apps, or links that send users to external sites to complete purchases, alongside its own in-app purchasing. The company stresses that purchase history, subscription management, and refunds will not cover transactions handled externally, and warns of cybersecurity risks from opening iOS to rival marketplaces and processors. To offset lost control, Apple is introducing an authorisation process for app marketplaces and baseline reviews for all iOS apps.
How Global Rules Are Fragmenting Apple’s App Store Strategy
Taken together, these moves show how global regulation is dismantling a unified App Store and payment strategy. In Europe, the DMA pushes Apple toward equal technical access and bans restrictions on communication about off‑platform offers, striking at how Apple favours its own services. In Brazil, authorities have forced concrete structural changes: approved third-party app stores, alternative payment options within apps, and lower or differentiated commission rates for many developers. “The watchdog found that these practices created ‘artificial entry barriers’ for competitors selling apps and other tools to iOS users.” Instead of one set of rules for all, Apple now runs a patchwork of DMA compliance requirements and local antitrust remedies. For developers, this opens new ways to reach users and reduce costs, but also introduces complexity. For Apple, it marks a shift from platform owner to regulated gatekeeper whose business model is being redesigned from the outside in.
