Just last week, 8,158 people got Nomorobo protection!


i still gt calls from "portfolio recovery" every day, 3-4 times a day.the phone numbers displayed are different.

Nomorobo is a terrific product --- says what it does and does what it says. I'm delighted with the results and have recommended it to several friends and family members. The only thing that could possibly make it better would be if that single ring could be eliminated although I realize that might not be technologically possible. Plus then I'd miss out on the immediate satisfaction of knowing that another phone scammer had the electronic door slammed in their face. :-)

I love it. It has greatly cut my junk calls. I still get some when they change numbers. I hope you track those as well. Happy Holidays!

Not thrilled. Phone still rings twice with robocalls so, to me, it's not blocking them 100%. It also doesn't "know" legit calls from robo calls and so people have to redial after hearing so sort of message. I'm still getting calls I shouldn't get...unless the robo cretins have figured out how to get around this system.

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

like it but wish it did not ring at all

i LOVE it! it has made a huge difference in the amount of calls that are unwanted. thank you aaron!

This is a highly effective service. It has blocked so many calls to my home phone. At first I checked every call that didn't make it, worrying important calls might be blocked. Each and every time it was a spammer. I still have a few that get through once in a while. Is there any way I can report those to you for possible inclusion in your blocking service?Thank you so much for this invaluable tool, ... Dee
