RoboShield allows you to customize your call blocking. However, unlike RoboKiller, it indiscriminately cuts off those calls and doesn’t provide options to screen the calls before blocking.

Like most spam blockers, RoboShield simply blocks calls from phone numbers on a block list—the problem is, scammers can just change numbers to get around that. RoboKiller, on the other hand, uses machine learning to detect scammers based on their unique audio fingerprints. Scammers may change their numbers, but they can’t change their voices.

Unlike RoboKiller, RoboShield does not offer SMS protection. Our spam text blocking is 99% effective at identifying and shutting down text scams.

Some robocallers imitate local phone numbers so you’re more likely to answer them. Unlike RoboShield, RoboKiller knows how to identify and stop these sneaky spam calls before they reach you.

RoboKiller doesn’t just block robocalls—we make it fun. Answer Bots intercept incoming spam calls and mimic a real person to waste telemarketers’ time. You can even listen to the recordings. It’s a little poetic justice (and bonus entertainment) that RoboShield just can’t offer.
