Just last week, 8,256 people got Nomorobo protection!

Lifesaver!And this despite the fact that it only traps 50%-75% of the robocalls. Still way better than nothing.

It's great! Let the phone ring once. If it rings again, it's real. In not, we say, "Gee, Thanks, NOMOMOBO!

It seems to be working fine.I'm getting just a single ring now and I assume that's a call you've intercepted? Also, are you intercepting calls from WITHIN my state? (California)
