Good work

MOST EXCELLENT app. It truly works.

What a relief!! This is the best idea in years.

Very happy with it. Works well.

I love it. The instant I signed up the calls were significantly reduced

It is terrific. I have recommended it to friends and family; unfortunately, some have Comcast and cannot make use of this wonderful program. The only thing better than the one ring--which is music to my ears--would be no rings. Who knows, maybe someday?

No more tension when the land line rings. Can't believe how quickly it worked unlike going on the do not call registry.

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.
