Like Robokiller, Nomorobo offers users the ability to customize their block and allow lists. However, Robokiller's 99.9% effective spam identification and blocking ensures you're protected against risky calls that aren't in your personal blocklist.
Like many spam blockers, Nomorobo simply blocks calls by category against phone numbers on a blocklist. 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.
Nomorobo needs to run in the background to work, which means Background App Refresh needs to be on. And, if you restart your iPhone, you’ll need to relaunch Nomorobo to get it to work. Robokiller protects you from spam calls all the time, whether the app is running in the background or not.
Some robocallers imitate local phone numbers so you’re more likely to answer them. Nomorobo does offer some anti-spoofing features, but Robokiller knows how to identify and stop these sneaky spam calls before they even 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 Nomorobo just can’t offer.
Nomorobo 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.
