What Are Your Options for Free Call Blocking?
If you’re facing frequent spam calls, you may feel overwhelmed by the number of options available today. The three primary apps frequently recommended are Robokiller, Truecaller, and Hiya.

For everyday users in the United States, Robokiller is designed to target spam calls before they even ring, using advanced technology to keep unwanted calls at bay. (source)
How Does Robokiller Work?
Robokiller provides a free trial, enabling users to block spam calls and texts effectively. It utilizes a vast database of known spam callers and employs machine learning to identify and block these calls, promising a reduction in spam calls potentially up to 99% for paying users. (source) The app's personal blocklist feature allows users to choose which numbers they don't want to be disturbed by, offering a customizable blocking experience. (source)
Why Choose Truecaller?
Truecaller distinguishes itself with features like the ability to block hidden and private numbers for free on Android. It relies on a community-sourced database to identify spam calls. While it offers a robust free tier, certain advanced features are only available in its paid Premium plan. (source) This makes Truecaller a suitable option especially for those using Android devices.
What About Hiya?
Hiya offers a free core app for blocking spam but encourages users to consider its Premium tier for advanced capabilities. It primarily operates through networks, which can result in integrations that provide caller ID and calling reasons, but could also lead to some calls being silently blocked. This method may be less preferable for users who like visibility into their call blocks. (source)
