The UK Competition and Markets Authority (CMA) revealed today that Apple and Google have agreed to a set of reforms aimed at leveling the app‑store playing field for developers. The regulator had labeled the two firms a duopoly with “strategic market status” last October, a designation that grants it powers to compel competition‑boosting changes for UK consumers.

Under the CMA‑published terms, both platforms must review and rank apps in a “fair, objective and transparent” manner, without disadvantaging services that compete with their own offerings. They also pledge to protect developer data gathered during the review process. Apple faces an additional interoperability clause, requiring it to simplify requests for access to iOS features, potentially opening its ecosystem to rival apps and access.

The reforms take effect on April 1, pending a public consultation that runs through March 3. The CMA warned it will closely monitor compliance and will not hesitate to impose formal requirements if either company falls short. Future steps may target other services, such as Apple’s digital Wallet app, ensuring the UK market sees a more open mobile ecosystem in the UK.
