Just last week, 8,272 people got Nomorobo protection!


Signed up a few months ago and I love this service! No more annoying calls with "delayed operators" reading scripts, or robot recordings!

I love Nomorobo. It has dramatically reduced the number of unwanted commercial telephone callsI receive.. I have recommended it to my friends when they complain about nuisance calls.

I love it. I recommend it to everyone I know.

Great!!!!!Most telemarketer calls are caught, but the telemarketers don' t give up!

love it

I and my wife just love it. It rings once and bam there gone. Only one minor problem. I'm getting calls from the same caller over and over again. This in minor to me because it still blocks them an only rings once. I can't thank you enough. We installed the app just before election time, and let me tell you it blocked a lot of calls. Great app. We can't wait for this to work on cell phones. I give it a 5 star +. Best regards Bill

I wish it would not ring once when a robo call comes in. Can't the call be completely blocked instead?

This is the best thing to come along since sliced bread! I am so impressed that it does what it is supposed to do - gets rid of unwanted calls by the second ring...HOORAY!
