Unlike other call-blocking solutions that rely solely on user feedback, Robokiller uses a predictive spam call blocking algorithm that proactively analyzes each incoming call before it rings your phone, and determines whether it’s spam — all in less than a millisecond. We also audio fingerprint the robocall and store it in our global database so they can’t strike again.

Our technology is 99% effective at stopping spam calls and unwanted messages.
