In the European Union, the Digital Markets Act allows developers to distribute iOS apps through alternate app stores. While Apple checks those apps for malware and other malicious content, there are few restrictions on subject matter, unlike Apple's own App Store. As a result, EU users can now download the first dedicated native pornography app created for the iPhone. Called Hot Tub, the app is available through the AltStore PAL, an EU app marketplace from developer Riley Testut.
