This app really works great for the annoying calls I have been getting. it has caught about 95% of them. however, somehow it also blocked access to my texts. still trying to figure that out. one caution about this though. I tried the free trial and canceled after 2 days (because of the text issue, which they still haven't addressed) only to find out i was billed anyway from the day i started the trial. when i questioned it, i was refused a refund. I hope the calls will stop when the year is up.

app is easily defeated. all the blocked caller has to do is hangup and call back right away. the app ignores the second call and the spamming callers know this. when I asked customer service about a way to disable the second call feature all i keep getting is AI responses or they are not really reading the issue. i definitely won't be renewing my subscription unless they fix it.

Awesome app...but tripled the price this year. I originally gave it 5 stars because of the performance and the value. Today I received notice that the annual price is going from $24.99 to $74.99 on July 17th. Won't be renewing with a $50 increase. I'd stay with a $5-10 increase. I'll survive filtering my calls on my own. Sad, cuz I recommend this app to dozens of people over the years.
