Are you receiving a litany of unwanted messages or phone calls from random phone numbers? Are you bugged continuously by an unknown number in the middle of the night? If your answer is yes, chances are you’ve fallen victim to the dark side of mobile communication. The only way to stop these pointless calls is to install the best call blocker apps.
As the name implies, a call blocker app gives you the power to block unwanted calls that may cause a disturbance in your activities. It allows you to flag unknown numbers and prevent them from bothering you again.
The bogging calls you’re receiving can be automated calls with prerecorded messages, otherwise known as “robocalls”. Other times, those can be cold calling from telemarketers, offering products and services. In a worst-case scenario, those can be spoof calls. A spoofed call duplicates a number from your area code or even your mobile number. It’s a kind of technique that scammers employ in order to trick someone to answer a call. Learn the ways to identify the source of the call via our guide on how to track phone numbers.
You can also rely on many call blocker apps that provide an excellent suite of tools for addressing the problem. Some of them may require subscription fees, while others are mostly free.
If you don’t have any idea which one to download, you can refer to our list of best call blocker apps. Here are the 13 options to check out.

Another is it doesn’t only utilize your localized blocklists. Instead, it searches its always-updated RoboKiller global blocklist to know if a number falls under spam or not. And to seal its place as one of the best call blocker apps, it also protects you from spoofed calls, as well as spam SMS.

Doing either of the two actions will prevent a certain number from ringing your phone.
When using Nomorobo, note that you’ll always hear the first ring of the call. If the app detects it as spam, it automatically catches the call and blocks it. If the call continues to ring, that means it’s credible so you should probably answer it.
