Given the different DMA compliance timeline for iOS, recent changes to iOS in the EU can be an indication of what’s going to happen for iPad users in the EU.
There are five third-party app stores that are now available for iOS in the EU. One example, the AltStore PAL, was the first alternative app marketplace made available on iOS in the EU. You can use it to download video game emulator app Delta, virtual machine app UTM, torrenting app iTorrent, and more.
