Unlike RoboKiller, 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’s spam list protects from scam calls all the time - whether the app is open, running in the background, or not.

Answer Bots
RoboKiller doesn’t just block robocalls – we make it entertaining. Answer Bots answer your spam calls, mimicking a real person and driving telemarketers crazy. You can even listen to the recordings. Nomorobo can't do that.

Audio Fingerprinting
In addition to blocking known spam numbers, RoboKiller can detect scammers based on their audio fingerprints. Scammers may change their numbers but they can’t change their voices. Nomorobo can't do that.

Neighbor Spoofing Blocking
Robocalls can now imitate local phone numbers so you’re more likely to answer them – it’s called neighbor spoofing. RoboKiller knows the difference and protects you from spam calls. Nomorobo can't do that.
