Just last week, 8,253 people got Nomorobo protection!

Love this service. I tell people about it frequently. Would even pay for it...if it came to that.

NOMOROBO actually works and works well! I would not be without it. I enjoy hearing the one ring and then silence.

When I only hear one ring, I know that you've snagged another one of those annoying calls. Thanks tons for all that you do!

Satisfaction # 1: Hearing the phone ring only once and knowing the caller is history.Satisfaction # 2: Reporting callers that did bother me. Thank you many times a week. I have told lots of people about Nomorobo.

Not only does the service work nearly flawlessly - no false positives I've been told about - but also it's simple to work with their helpful people to research and add new numbers that should be blocked. I'd be completely happy to pay for the service to make sure it stays online, yet they refused when I offered. Amazing.

Works just like you said it would. Now if I could only get rid of "live" callers that keep trying to sell me something.....

This is a great App that everyone who hate robo calls should have. In fact, this should be standard feature on all phones and if anyone crazy enough to want robo calls, they could deselect the feature. The App could use a feature that would allow a "blacklist" to block unwanted calls.
