RoboKiller review
A feature-rich freemium blocker for robocalls, spam texts, and unknown callers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
RoboKiller is a mobile spam-call and spam-text blocking app for iPhone and Android users. It combines predictive robocall blocking with audio fingerprinting, caller ID, unknown-caller screening, spam text filtering, custom block and allow lists, and spam voicemail protection. It is suited to people who want more than basic number blocking, particularly those looking for caller screening, intercepted-call handling, and community-based spam reporting in one app.
Its strongest distinction is feature depth. RoboKiller can screen unknown callers by requesting their name and reason for calling, while Answer Bots handle intercepted spam calls. Spam Patrol and user spam reporting add a community reporting layer, and the app also provides global blacklist access, spam-call notifications, and weekly spam-blocking insights. Together, these tools address calls, voicemails, and texts rather than focusing only on incoming robocalls.
According to the published plans, RoboKiller uses a freemium model with a Free plan and a 7-day free trial. The Free plan includes global blacklist access, spam-call notifications, weekly spam-blocking insights, spam reporting, and Spam Patrol. The product description identifies call screening and Answer Bots as paid features, so buyers seeking those capabilities should expect to move beyond the free offering. RoboKiller is a strong fit for users who want advanced mobile call protection across iOS and Android; those seeking a wholly free experience with every screening and response feature should consider a simpler blocker instead.
