Informational (neutral): "Duet Display IPA repack refers to a redistributed package of the Duet Display iOS app bundled as an .ipa file, often modified to bypass App Store installation or include unofficial features. Using repacked IPAs can expose devices to security risks, violate app terms of service, and may infringe copyright. For safe use, obtain apps through official app stores or the developer’s official distribution channels."
: Standard App Store IPAs are encrypted and won't work if simply moved to another device. You must use a jailbroken device with tools like duet display ipa repack
