I have an iPhone I'm trying to restore and the backup keeps failing. The only thing I can think of is that it's prompting me for a family member's Apple ID. I never had to enter that password to install an app in the first place, so I'm confused why it's asking for one on restore, but that's another question.

This question is - what do I need to do 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.

How can I identify the signing identity used for each app on the iPhone?
