The tools you need to live spam-free

Here are some of RoboKiller’s unique features (that you can’t get with Nomorobo):
settings

Customizable call blocking

Nomorobo sends all unknown callers to voicemail, and doesn’t offer any call screening services — that doesn’t give you much control over your phone. RoboKiller’s advanced call blocking capabilities include real-time call screening, so you can get the name and intent of every unknown caller before you answer. Plus, you can create custom block/allow lists, so you never miss a call you actually want.
stop spam

Protection against neighbor spoofing and caller ID spoofing

Some robocallers can imitate local phone numbers so you’re more likely to answer them. Unlike Nomorobo, RoboKiller knows the difference and protects you from these sneaky spam calls, regardless of the number they’re calling from.
audio fingerprint

Audio fingerprinting

Like most spam blockers, Nomorobo relies on blacklisted phone numbers to block calls — which means scammers can just change their numbers and get through. RoboKiller, on the other hand, uses machine learning to detect scammers based on their audio fingerprints. Scammers may change their numbers, but they can’t change their voices.
phone

Answer Bots

RoboKiller doesn’t just block robocalls — we make it entertaining. Answer Bots answer your spam calls, mimicking a real person and wasting telemarketers’ time. You can even listen to the recordings. It’s a little poetic justice (and bonus entertainment) that Nomorobo just can’t offer.
loudspeaker

24/7 protection

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 from scam calls all the time, whether the app is running in the background or not.

Smarter spam text blocking

Nomorobo does offer SMS protection, but it can’t keep up with spammers like RoboKiller can. Our spam text blocking is 99% effective.

Silence from spammers. Praise from the press.
