TrueCaller doesn’t offer any call screening services and only blocks calls based on caller ID—so much for security.
Like most spam blockers, TrueCaller 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.
TrueCaller also offers SMS protection, but it can’t keep up with spammers like RoboKiller can. 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 TrueCaller, 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 TrueCaller just can’t offer.
