Apple will be allowing third-party app marketplaces on the iPad in the European Union in iPadOS 18, with beta testers getting a chance to look at the feature in iPadOS 18 beta 2.
In response, Apple said it would comply with the EU’s decision. Consequently, third-party App Stores will be supported on iPadOS, though Apple has not given a specific date. The support will come with an update to iPadOS in the fall.
