The best tool ever!
I'm a housewife and I often get insurance and spam calls for sales. Also confused by harassing phone calls, so I chose to try Robocall Blocker. Through using over 3 months, I felt very satisfied with what it brought to me. Now harassing calls can hardly reach me.

Shoutout to the developers!
I used to receive more than 10 robocalls a day on average, which made me very upset and angry. But on the other line was a recording bot, and I could not break it until I used the app. Now I let the chatbots fight robocalls and waste their time.
