Community Voice & Feedback
Doesn’t scan most calls and let’s obvious scam calls and voicemails through, even calling them “safe”. Cancelled the trial.
Great
Do not think about downloading this. This app doesn’t work at all. It won’t even load up and do what they charge you an arm and a leg for. And if you need help, there isn’t a human involved. It’s all done by AI. I’ve asked for a refund and have been denied twice. I’ve contacted the developer for a refund and they say Apple controls that. I call foul on that. So now I’ve wasted $100 and still have spam calls.
I was excited to download this and see if this could be a solution for the 10+ scam calls I get a day, but my god, $8/wk or >$100 a year? For a spam blocking app? In this economy?
All the scam/spam calls I was receiving have been deleted before my phone rings now. So calming.
Robbed me of $120 . Sub is $30 a year max. There policy subverts to apple who says after 2 days and a 4 x charge that it doesn’t fit refund policy . So sick of these corps taking advantage and now robbing us in plain sight against there own policies
Great

Try clicking on the Support links. Theyre fake. Click on Call Forwarding Troubleshooting. Just takes you back to Turn on Call Forwarding page that doesn’t work. A worthless scam
They make you jump to all the hoops and answer all the questions then they want your credit card for a free seven day trial.
Would be 5 stars if there wasn’t a 5 digit minimum on blocked call ranges. Should be able to block all calls by area codes. Majority of all spam calls I get stem from a handful of area codes but since there’s a 5 digit minimum I still get bombed with spam calls.
I get calls from people all the time who “pass” the call screener without ever entering anything. Frustrating. No customer service to talk to
