2018-10-22 Doesn't work as advertised. It only tells you what you already know from your phone call logs. 'Unknown Caller'. It does have a link to Google the number (as if you weren't already doing that). Waste of time. Edit: since uninstalling i've received even more unwanted calls from suspicious numbers. I'd suspect this app company distributes your personal info.
