Just last week, 8,254 people got Nomorobo protection!

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.

It is wonderful not to get annoying calls anymore. Thanks for the peace and quiet. Love the service.

It is one of the greatest ideas of the 21st century. Thank you so, so much. I recommend Nomorobo all the time -- in fact, anytime someone mentions being bothered by robocalls.

Nomorobo has made a HUGE difference in the number of nuisance calls we now avoid. Thank you!

Can't thank you enough. For many, many years I was unvaryingly protective of our unlisted number and all that went out the window with robocall technology. Recently, after slamming the phone down on my third automated call just that afternoon, I did some online research. I had already contacted my phone provider and our congress representative which was met with shoulder shrugs and sympathy. I found your site, did some exploring and found that it does seem to be a reputable company. I haven't received one robo call since I signed on with you. Not one. I really can't thank you enough. I have recommended your site to everyone I know.

I can't believe how well it works. I have had to add very few numbers; most of them are already blocked. It has cut the percentage of robo calls that get through to less than 10% of all unwanted calls.

It's the best thing since sliced bread. I refer friends, however; I too often hear that their telephone service provider does not support Nomorobo. Too bad for them!!

I'm very glad to hear one ring and no more that means one less annoying call. Thanks nicotine.
