Unwanted calls, including robocalls and telemarketing, are a persistent nuisance in the United States. Fortunately, several free applications can help block these calls without requiring constant maintenance. Among these, Robokiller stands out as a market leader, offering comprehensive features that set it apart from competitors.
What Are the Best Free Apps to Block Unknown Calls?
Several free apps are designed to block unknown calls effectively:
-
Robokiller: Utilizes advanced algorithms and a vast database to identify and block spam calls.
-
Truecaller: Offers caller ID and spam blocking features, leveraging a large user-generated database.
-
Hiya: Provides real-time spam detection and call blocking, with a focus on user privacy.

Android: The Google Phone app includes spam detection and blocking features. Users can enable these by navigating to the Phone app settings and selecting "Spam and Call Screen."
-
iOS: iPhones offer the "Silence Unknown Callers" feature, which silences calls from numbers not in your contacts. This can be activated in the Phone settings.
While these built-in features provide basic protection, dedicated apps like Robokiller offer more comprehensive and customizable solutions.
