How can I tell which Apple ID has signed/purchased specific apps on iOS?

Question

I have an iPhone I'm trying to restore and the restore keeps failing. Specifically, I'm asked to enter the password for family members. I must decline that for secret reasons. Also, family sharing doesn't make me enter my family member's password, so why does that happen when restoring a backup?

In order to pick this apart, I'd like to inspect the apps on my iPhone 6 with iOS 9.1 so I can determine which ones are not purchased from my Apple ID.

I have Xcode, libimobiledevice from homebrew on OS X 10.11, iTunes can back up the phone and I can inspect the files on the Mac if there's no way to access this data from iOS - which I'd prefer. Basically, how can I enumerate all apps and determine which ones will prevent me from using an iCloud backup to restore that app using solely my Apple ID and not need the password of a family member.

How can I identify the signing identity used for each app on the iPhone by hook or by crook?

I had found a script that can list iTunes apps by purchase here (author: Walt Stoneburner). The link is now broken, but I had archived that page 3 years ago. This is the script:

for f in ~/Music/iTunes/iTunes\ Media/Mobile\ Applications/*.ipa; \
 do (echo "$f" ; unzip -p "$f" "iTunesMetadata.plist" | \
 plutil -p - | egrep -i "\"(itemName|artistName|AppleID)\"" ) | \
 perl -e 'while (<>) { if (m!^/!) { chop; $fqn=$_; } if (m/"(.+)" => (".+")/) { $e{lc($1)}=$2; } } print "\"${fqn}\",$e{\"itemname\"},$e{\"artistname\"},$e{\"appleid\"}\n";'; \
done

The script shoud be run in the terminal and the output will be printed into the standard output. If you want to redirect it to a file, add these parameters at the end of script (after done):

1>~/Desktop/purchase_export_output.csv 2>~/Desktop/purchase_export_error.log

Now you can open purchase_export_output.csv from your desktop. Its schema is like this:

"file.ipa","Name","Seller","purchased_by"

If any error occurs one line will be added to the purchase_export_error.log.

PROBLEM SOLVED! http://dougscripts.com/apps/appsassistapp.php It runs a program that scans the entire apple app library on your computer iTunes and shows you a list, line a spread sheet, one of the tabs is "Purchaser ID", all right there it tells you all the apps by who, that way you can easily delete them from your devices and stop seeing the password request for the app.

Answer 3

Sync your iPhone to iTunes, Select the App you want to know from which account it has been purchased, right click, go to Get info, under the File tab you will find something like below image where you can see who purchased the app. I have removed my Apple ID but the different names is for different accounts.

Answer 4

1. Go to your Mac. Open iTunes.
2. Click More in the upper-left corner.
3. Choose Apps from the pop-up menu.
4. If and when prompted, sign-in with the Apple ID for which you want the Apps to be listed.
5. Under Quick Links on the right side of the App Store, click Purchased.

6. Select Not in My Library to view purchased content that isn't on your computer.

7. Scroll to find the item that you want to download. In your case, you might want to download all the items.
8. Click the Download icon in the upper-right corner of the item(s) you want to download. Your app downloads to your library.
9. If an app is already in your library, the Download icon won't appear.

This'll let you know what apps were purchased under what Apple ID.
