Choosing Between Nomorobo and RoboKiller for Blocking Sales Calls

When it comes to blocking sales calls, two prominent services stand out: Nomorobo and RoboKiller. Both aim to reduce unwanted calls, but they differ in features, effectiveness, and user experience.

What Are Nomorobo and RoboKiller?

Nomorobo is a call-blocking service that intercepts incoming calls after the first ring. It maintains a database of known robocallers and uses this information to determine whether to allow or block a call. Nomorobo is compatible with landlines and mobile devices, offering protection against a wide range of robocalls. (washingtonpost.com)

RoboKiller is a mobile application designed to block spam calls and texts. It utilizes artificial intelligence to identify and block unwanted calls, and features Answer Bots that engage with robocallers to waste their time. RoboKiller is available for iOS and Android devices. (robokiller.com)
