As mentioned elsewhere, the learning curve for setting up the various filters is very steep, but it works brilliantly, and in my experience at least, flawlessly.
I used to get multiple unlisted and spoof number (similar to mine) calls every day. I tried TrueCaller and some other apps that didn't work very well. This reliably blocks all of them, without even a ring, and lets other numbers through. The interface is a little clunky, but I'm not dinging it for that since it works so well where other more highly rated apps failed.
Lack of readily found instructions is the only flaw... once you get past that, this is a sweet app! (I have tried just about every other one... this one is a keeper!)
I just wanted to automatically send calls that were not from my contact list to voice mail. This app did just that. After trying many apps to do the same thing I am glad I have found a solution.
Hey guys it stopped working after Oreo update. Kindly add Oreo support too.. please... :)
