Apple have removed App Store from iTunes in version 12.7, this makes it much more difficult to download an IPA from the App Store.
However this can now be achieved by using Apple Configurator 2.
You need the following:
- Mac with Apple Configurator 2 installed
- iTunes account on which the application in question is purchased
- iOS device that can install the app
- Cable to plug iOS device into the Mac
- App in question already installed on the iOS device
First you need to sign into an iTunes account in Apple Configurator, this is done via Account -> Sign In
Once signed in plug in an iPhone into the Mac and go into all devices.
Right click on the device and go into Add -> Apps…
Find the app in question and hit add
Configurator will start downloading the app
You will be prompted with the message "The app named already exists on ", do not select any of the options instead open terminal.
In terminal navigate to
You should see a directory with a randomly generated ID, if you drill into it (any any directory inside) you should see the IPA file
