Just ok

Its nice to identify a SPAM number. The only problem is that if you blacklist the number on the app, it will still ring through the next time they call and show it as blacklisted. If you want to block the number, you have to do it on your phone manually prior to blacklisting it. If you blacklist it first, it will forever ring on your phone every time they call.
