An outstanding service. Brilliant idea. Thank you!

Great service, and I'm enjoying a good chunk of those 70,000 calls you block every day. The only improvement I can recommend is some way to mute the single ring that you're unable to stop. Guests sometimes ask why our phone rings only once, which does give us the opportunity to explain your service. Keep up the good work.

My husband has Alzheimer's & the constant ringing of the phone was driving him & Me crazy, he could not understand why I would not answer it. I feel like someone was looking down on me when I found your service - my phone has been quiet since the day I started & if it is a rare important call it comes right to my iPhone in readable text

Great. One ring and the call is gone. Thanks.

For every action there's a reaction, Nomorobocalls!

Wonderfull!! Please get rid of political calls too, okay? :)We would pay for that service!

It is the greatest. I tell all my friends and family about it.

Mr. Foss,Thank you for a GREAT App. It is a stupendous success in my household. I just wish there was some way to track the real source of these calls so we don't have to play Whack-A-Mole every time the scammers just spoof another phone number.
