How Callro Spam Blocking App Filters Spam Calls

Callro is a spam blocking app with a powerful, multi-layered defense against unwanted calls. But true peace of mind means having control over how that protection works. That's why we designed features that let you customize your defense to match your lifestyle.

Smart Spam Blocking Modes for Every Situation

Fortress Mode

Complete silence when you need it most.

Blocks all calls, with the exception of emergency numbers and contacts. Ideal for focused time, dinner, or meetings. To activate, simply tap. Calls in an emergency are always answered.

Manage Prefix Rules

Stop entire area codes or number patterns.

With a single tap, block particular prefixes like "979" or "+44." Prevent international robocalls and neighbor spoofing before they start.

Block Repeated Callers

Auto-stop persistent numbers.

Callro automatically blocks subsequent attempts if the same unknown number calls repeatedly within a brief period of time. No more being harassed.

Night Mode

Automatic protection while you sleep.

Establish quiet times (by default, 10 PM to 7 AM). Silenced were unknown numbers. The only calls that come through are contacts and emergency calls. Take it easy.

Callro works silently on your background, yet we have also created some nice features for the app itself that make it very enjoyable to use.
