BRUSSELS (Reuters) - Apple will extend a newly introduced core technology fee to iPadOS apps downloaded on its App Store after the operating system for iPads was added to a list of key services subject to EU tech rules, the iPhone maker said on Thursday.

Apple in March announced a core technology fee (CTF) of 50 euro cents per user account per year for major app developers even if they do not use any of its payment services or its App Store, with the first 1 million user accounts exempted from the fee.
