European regulators are reviewing whether Apple’s latest App Store rules meet the requirements of the Digital Markets Act, according to people familiar with the matter. The examination adds fresh pressure on the company as Brussels continues to enforce tougher competition standards on major tech platforms.

The probe centers on whether Apple’s updated terms and technical changes still give developers fair access and whether the company has fully addressed concerns raised under the EU’s landmark digital competition law. The law was designed to curb the power of dominant platforms and open markets to rivals.

Apple has already faced criticism from app developers and regulators over fees, restrictions, and the way apps are distributed on iPhones. Any finding of noncompliance could lead to further demands for changes or potential penalties, though the scope and outcome of the review remain unclear.

The case underscores the broader clash between Big Tech and European regulators, who have taken a harder line on gatekeeper platforms in an effort to protect competition and consumer choice.
