This is my first question here and my question may sounds novice but I am going to spend my vacation abroad so I would like to make sure that my iOS devices are pirated free content.
I may have copied some contents from friends such as ebooks, music, videos, etc. The problem that I have tons of apps so I may use multiple book readers such as iBooks, Kindle, and many others. Same applies for music and videos.
Is there a way to check all of the contents on my devices using an app or at least a systematic way for check up.
PS: my devices are 256GB and all apps are original and downloaded from app store.
