Just last week, 8,259 people got Nomorobo protection!

Wonderful App. I appreciate that when my phone rings once and stops, Nomorobo has zapped another unwanted call. When one does get through, I place it on the Nomorobo list and never get it again.THANKS!!

We have had Nomorobo for months now. My wife and I love it. It REALLY works! It has saved us from answering many, many annoying calls. Cudos to Nomorobo!

excellent tool

Nomorobo has been a blessing in our house where we watch 2 young boys. One ring and gone, no chasing the phone instead of the boys.Only issue is some other Time Warner Customers hear only one ring at their end and assume they lost a connection. The phone in our house keeps on ringing. Regular callers have been informed of this issue and they wait us out.

Unbelievably good on phone service providers that accommodate this application.

Thank you. Thank you. Thank you. You made me a hero in my wife's eyes when I stumbled upon your service. When the phone rings just once, I can only smile, because I know another robocall has been blocked. In fact a robocall was just blocked as I write this! Keep up the good work. Can't wait for your service being available for smart phones.

Nomorobo gives me the ability to strike back against the illegal and unwanted practice of robo-calls. I just hope you are reporting them to the proper government authority, and that they in turn will carry out their obligation to the American people through fines and penalties.
