Just last week, 8,277 people got Nomorobo protection!


I like the fact that the phone rings one (1) time and I know that Nomorobo has just "gotcha"

Love it, it stops 90% of the calls that I don’t want. Thanks

MOST EXCELLENT app. It truly works.

I've already recommended this to friends. It's a great service that is effective 98% of the time. The political campaign calls always sneak through, of course. But we're highly pleased with the service. It's nice to hear calls from telemarketers ring only ONCE.

I thought I liked it at first. But soooooo many calls get through! The other day it was 3 in one hour. Why is that??????And almost never get the single ring that signifies a blocked call.

It's Great !I saw it on a news report from a consumer reporter, I caught just the end of the report. The reporter said there was a new thing out called "Nomorobo", that worked better than the "do not call list".I googled "Nomorobo" it's been "Blissful Silence" ever since.

We are extremely pleased with Nomorobo's service! It daily blocks at least half a dozen calls. I love hearing that single ring, knowing that this amazing service is doing it's job! LOVE IT!!!

My husband and I love it. What did we do before nomorobo!! We got aggravated by robo calls!! We're getting new cell phones in about 3 weeks and will sign up for the mobile Nomorobo then. Thanks!
