Just last week, 8,279 people got Nomorobo protection!


I love Nomorobo and have told a lot of people about it. It has made my life so much easier. I am a senior citizen. It has stopped many, many, many annoying calls. Thank you so much.

I don't know how anyone could live without this wonderful programming in the world of today! A million thanks for the caring and determination you put into this for all people, everywhere. While there is still much to be done on the scamming front...calls to my home from Robo sources average about 75 -80% of all my calls. Those folks calling blocks of numbers at one time and single Robo calls have finally met their match and I finally have some long needed peace! I recommend it every chance I get to everyone I know!

Good work

This works great, 1 ring & gone,TOO bad it can't stop the Political & Charities, I give to whom I want to, not to callers.

it is a great program invented by a great new york person, since I installed on my home phone I have some peace of mind..no words to thanks this person, I can only say: God bless him forever

Its Great! I can now sit down and have dinner in peace.

I have mentioned you on FB dozens of times. You service is awesome and I recommend it to everyone. I make at least one report daily now from all the calls I get. I love it when it rings once and then hangs up. that is AWESOME Thanks.

Total joke. You need to sign up for a smart phone service for it to work on your home's landline. How stupid is that? Very. Absolutely useless unless you're one of the many drones out there walking around staring at a little screen in your hand.
