Summary
RoboKiller is an Android and iOS app for blocking spam calls and filtering spam texts. Its predictive algorithm analyzes call metadata in less than a millisecond and blocks calls it identifies as spam before they reach the phone. Audio fingerprinting compares robocall recordings in real time with a database of more than 1.5 billion processed phone numbers and millions of audio fingerprints. RoboKiller states that its technology is 99% effective at stopping spam calls. The free version includes a daily-updated blacklist, blocked-call notifications, weekly insights, spam reporting, and Spam Patrol. Paid plans add Answer Bots, Call Screening, and Personal Data Protection. Answer Bots use prerecorded messages with spam callers; Call Screening asks unknown callers for their name and reason for calling. Both features require a carrier and plan that support Conditional Call Forwarding. Text filtering uses block and allow lists, number reputation, and content analysis; RoboKiller says messages are never stored or shared. Listed paid options are 4.99 USD per month, 31.99 USD per year, and 39.99 USD per year.
