I'm learning how to use app ! I hate spam calls !
★☆☆☆☆Peggy Nance· Dec 18, 2025
It worked ok for a while, but then it started to stop my allowed calls after ringing. So I removed it. It stopped all my calls with names on them. But allowed spam calls to call all the time. it's a wast of time to also try to figure it out because it don't tell us what to do after installing it. I was really hoping for it to work good, but instead it messed with my incoming calls I want to receive. By stopping the call and my friends was like I tried to call you but not got through.

Well when you seriously make a spelling mistake on the first page saying 'have you every had this...', no way am I using the app. Looks dodgy with spelling mistakes like a foreigner has designed it. I'm afraid I've uninstalled it.
