Unlike Robo Shield, which uses a list of known phone numbers to block spam calls, RoboKiller's spam list is updated constantly, whether the app is open in the background or not. RoboKiller also combines live audio fingerprinting with known spam numbers to protect users against neighbor spoofing, which Robo Shield does not do.

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. Robo Shield 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. Robo Shield 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. Robo Shield can't do that.
