Nothing but spam comes from this app. I didn't even complete the setup, I had to stop after 12 full screen advertisements. so I don't know if it works to block spam through calls but you sure as hell get spam advertisements out of it.

Beautiful and easy to use interface. BUT: App takes over a minute to open when I want to make a call. Messaging does not support GIFs. I may be a little ol' school, but I do not want to view ads before I have to make an emergency phone call.
