You have one of the best and most comprehensive phone call blocking apps that ive seen, and I have tried may. I like that there are many different options to block and whitelist calls. The app has blocked all my spam calls. My support ticket was answered and fixed that same day

I have been getting a lot of spam calls lately and decided on this app. Using all the filters I still got spam calls, not sure why. So I use contacts only and whitelist area codes to let phone calls through. Glad app has these features. The call statistics do not work for me even when using the app as the default dialer. Hopefully this is fixed as it gives great satisfaction to see the stats. Lastly it says I can use my default phone app and blck grd, but then it needs permission again?guide pls

Absolutely love that I can allow the calls to voicemail but automatically stop the call from ringing or buzzing me, I love wasting the scammers time letting it ring and leaving a voicemail

Paid for the app & it's not working & customer service did respond to me but problem wasn't solved, but they refunded my purchase but I caution that if u do contact customer service if u don't respond in the timely manner they want they will lose patience with u& refund & uninstall the app from your phone, but they will respond and try to help fix the matter app worked great until the update but my 1 star still applies update: customer service has been sending horrible and harassing emails to me

I got this to filter text message spam, but it will not let me see messages without enabling the AI call screening role.

All I want is an app that doesn't allow spam to go to my voicemail. It has to be a high demand consumer product and yet no one seems to have made one. This one looked promising as it has an option where it SAYS the blocked number goes to a dial tone and not to VM. But I'm still getting a couple dozen spam calls every single week and have to delete them. I like that this one allows you to block area codes. But the AI bots just find a new one to use so .... pointless. I DID MAKE IT DEFAULT
