Trying to stop or at least limit Robocalls almost became a part time job for me. I would diligently try to use their "press 5 to be removed from our list" [yeah, THAT works!], & even more diligently report the numbers/caller ID in complaints to the Do Not Call Registry. Pretty much to no avail & a losing battle. Then I read about Nomorobo. Gave it a try & OMG, what a difference! An IMMEDIATE difference! A real Godsend --- The peace is wonderful. One little ring & then nothing. Thank you so much!!

Aaron foss is a genius. His Nomorobo technology continues to function above our expectations monitoring our home land line system, running interference against even the most persistent robo marketing calls! I cannot help but smirk when our phone simply emits the single ring, alerting us that yet another robo call has been blocked; hoorayyy for Mr. Foss. Our life is much less stressful knowing that Mr. Foss's electronic "secretary" is fielding unwanted incoming calls, especially those around dinner time. Thank you Aaron for all of your hard research and work to bring nomorobo to life!
