Extracting an App Store game’s IPA without jailbreak

Wait 5 sec.

Hello everyone, I’m a longtime member of this community, and it’s really great to see how much it has grown and come this far. I’d like to ask for your help with something. I have an iPhone running iOS 26.4.2, and as far as I know jailbreaking isn’t possible on this version. I downloaded an online game from the App Store, and I’d like to mod it and end up with a second, modified copy running alongside the original. The part about modding it (using AI models) and sideloading the new app next to the original with Sideloadly is already covered in the guides here, so I’m fine on that side. My actual question is about the very first step: without jailbreaking, can I pull the app’s IPA off my phone onto my PC? And is there any way to do this without having to buy an old jailbroken device just for this purpose? Thanks in advance
