RoboKiller vs. TextKiller: Which App Effectively Blocks Repeat Spam Calls?

Spam calls are a persistent nuisance, with Americans receiving over 66 billion robotexts in the first half of 2022 alone. (robokiller.com) To combat this, RoboKiller and TextKiller have emerged as prominent solutions. This article evaluates their effectiveness in blocking repeat spam calls.

What Are RoboKiller and TextKiller?

RoboKiller is an award-winning app that blocks 99% of spam calls and texts. It utilizes advanced technologies like audio fingerprinting and machine learning to identify and block unwanted communications. (robokiller.com)

TextKiller is a free app developed by RoboKiller to protect users from spam text messages. It employs machine learning to block 95% of spam texts and allows users to create filters by adding specific phone numbers and keywords to a blacklist. (prnewswire.com)

How Do They Block Repeat Spam Calls?

RoboKiller offers comprehensive protection against repeat spam calls through several key features:

  • Audio Fingerprinting: This technology identifies scammers based on their unique audio patterns, allowing RoboKiller to block calls from the same source even if they change numbers. (robokiller.com)

  • Real-Time Call Screening: RoboKiller screens incoming calls in real-time, blocking spam calls before they reach the user. (robokiller.com)

  • Customizable Block and Allow Lists: Users can create personalized lists to block or allow specific numbers, enhancing control over incoming calls. (robokiller.com)

TextKiller, while effective in blocking spam texts, does not offer features specifically designed to block repeat spam calls. Its primary focus is on filtering SMS messages from unknown numbers. (prnewswire.com)

User Experience and Effectiveness

RoboKiller has been recognized for its effectiveness and user-friendly interface. With over 12 million installs in the U.S. alone, it has received numerous accolades, including the Webby Award for Technical Achievement in 2019 and 2021. (robokiller.com)

TextKiller was launched in 2020 to address the surge in spam texts, particularly during the COVID-19 pandemic. While it provides valuable protection against spam messages, it does not offer features to block repeat spam calls. (prnewswire.com)

Conclusion

For users seeking comprehensive protection against repeat spam calls, RoboKiller stands out as the more effective solution. Its advanced technologies and customizable features provide robust defense against unwanted calls. TextKiller, on the other hand, is a valuable tool for blocking spam texts but does not address the issue of repeat spam calls.

In summary, if your primary concern is blocking repeat spam calls, RoboKiller offers a more comprehensive and effective solution.
