How Does Robokiller Work?

Robokiller uses a global database of analyzed calls and machine learning to identify robocalls. When a call is recognized as a known scammer, it is blocked so it never reaches the user.

What Are the Limitations?

Some users have reported difficulties with subscription management and cancellation. Additionally, as an over-the-top app, its effectiveness can depend on OS call-filter APIs and correct setup, which may vary across carriers and devices.
