I have used that to load old apps onto an iPad that I can't update.
Apple also makes iTunes 12.6.x available for download, but it's hidden on this page: https://support.apple.com/en-us/HT208079 - this is the last Windows version with IPA management, but there are also other ways to sideload IPA files without needing XCode and a developer signing certificate, e.g. https://codeburst.io/latest-itunes-12-7-removed-the-apps-opt...
The question is - how are we supposed to save and archive those IPA files today?
I should have said that I was asking how users can acquire IPA files without having jailbroken their device first.
I’ve used this to do other functions before, but not saving IPAs.

Why not get an Android then?
I use an iPhone 6 and have refused to upgrade iOS to the latest version, so there are quite a few apps that don't work on my phone anymore (when launched, they show a message saying I need to get the latest version of the app, but then I can't get it because it's not available for my version of iOS), one of those apps is YouTube, so I'm limited to accessing it through the browser. It would be great to have a good alternative.
