Just last week, 8,258 people got Nomorobo protection!

I frigging love it. Works well- too bad it can't block political telemarketing

Wonderful App. I appreciate that when my phone rings once and stops, Nomorobo has zapped another unwanted call. When one does get through, I place it on the Nomorobo list and never get it again.THANKS!!

I have told nearly everyone I know about Nomorobo. Never have I found an application that does what it says it will with such perfection! Absolutely outstanding. And such satisfaction on our end!

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
