This app seems to be doing well so far. So far I am very pleased with it, I can block calls without any problems.

Good service

It is blocking calls as it is supposed to do. I have no hesitation in recommending.

Don’t waste your time and money

This app literally does nothing. I work night shift, so I of course sleep during the day. I get several spam calls though out the day and it wakes me up every time (I’m also in the military so having my phone on ring is vital) and this app did not help me at all.

Developer Response ,

Hello, sorry to hear that you are not happy with our app. Our app does not automatically block spam calls as some of those calls may be essential for our customers, i.e. calls from banks. So, you need to blacklist those numbers. Please contact us at helpcenter@mad-duck.atlassian.net for further assistance.
