Automated calls, commonly known as robocalls, have become a significant nuisance for mobile phone users in the United States. These unsolicited calls often range from telemarketing pitches to potential scams, leading to frustration and potential security risks. Fortunately, several applications are designed to identify and block these unwanted calls effectively.
What Are Robocalls and Why Are They a Concern?

In 2025, Americans received over 52.5 billion robocalls, averaging roughly 13–15 spam calls per person per month.
