How can I determine who downloaded a free app and when they downloaded it if we have family sharing?

[iMore Question]

We have family sharing and random apps keep appearing. They are free and I would like to know who is downloading and when. No one usually owns up to the download so I would like to determine who downloads an app and when they downloaded it.
Thanks for any help you can offer!
