Call Blocker Regex

Tired of annoying calls from robocalls, credit card offers, or unknown numbers from overseas? Call Screener offers a smart solution for automatically screening your incoming calls.

Unlike standard call blockers, this app gives you complete control through its Prefix Input system. You can block thousands of numbers at once by simply entering a specific prefix.

Key Features:

Prefix-Based Blocking: Simply enter a prefix (e.g., 021, +44, or 08123) to block all calls starting with that number.

Automatic Disconnection: The app will instantly disconnect the call before your phone has a chance to ring.

Blocking History: View a list of numbers the system has successfully blocked.

Lightweight & Battery-Efficient: Runs efficiently in the background without draining your phone's battery.

Privacy Guaranteed: All block list data is stored locally on your device. We do not upload your contacts or call logs to any server.

Why Use Call Screener?

Many scammers use thousands of different numbers but with the same prefix. With the Prefix feature, you don't need to block numbers one by one. Just enter one, and all associated numbers will be blocked permanently.

Important Note (Permissions):

This app requires the READ_PHONE_STATE and ANSWER_PHONE_CALLS permissions to automatically detect and disconnect calls based on your specified criteria. We are committed to using these permissions solely for the app's functionality and to keeping your data secure.
