CallDetector, developed by PrivacyStar, is free to download, allowing users to access a basic set of features without any initial cost. Designed to help you manage unwanted calls and enhance your phone's security, the app provides call blocking, Facebook contacts backup, and unknown caller lookup with the free version.

While downloading and installing CallDetector is free, the full experience involves some optional in-app purchases.

Users should be aware that advertisements may be present in the free version, presenting an opportunity to upgrade to an ad-free experience through these additional purchases. It's always a good idea to review these options in the app's settings to determine what best suits your needs.
