What Is Robokiller and How Does It Work?

Robokiller is a call screening app that utilizes machine learning and a global database of over 1.4 billion analyzed calls to identify and block spam calls. Its patented audio fingerprinting technology ensures that even if scammers change their numbers, they can still be detected and blocked.
