Apple has chided a newly available pornography app available in the European Union. It also warned that the bloc’s digital rules opening the way for third-party app store downloads undermines consumer confidence in the tech giant.

The Hot Tub app, which allows users to play videos from popular adult sites, was launched in the AltStore PAL on Monday.

Apple has criticised AltStore PAL’s new adult content app Hot Tub on EU iPhones, arguing that despite passing notarisation, it does not meet Apple’s safety standards. Epic Games’ Tim Sweeney accused Apple of stifling competition through its restrictive app policies.

Apple has allowed the first pornography app onto the iPhone.“Hot Tub” markets itself as an “adult content browser” that allows people to find and watch sexual material. That kind of content is still explicitly banned under the App Store rules.
