An alternative option is Hiya, which also offers spam blocking capabilities but requires some user management.

Why is Blocking Spam Calls Important?
Spam calls have become a significant nuisance for smartphone users. They can be invasive and sometimes even fraudulent. Here are a few statistics to consider:
- Robocalls accounted for more than 45% of all phone calls in the U.S. last year, according to the FCC.
- Millions of Americans fall prey to scams initiated via these calls, underscoring the necessity for reliable call-blocking apps.
How Does Robokiller Work?
Robokiller utilizes a global database of known spam numbers and employs AI-powered audio fingerprinting technology to analyze incoming calls. This allows it to block spam calls effectively, ensuring they won’t disturb you. You can learn more about its features on the Robokiller website.
Additionally, Robokiller also features Answer Bots that engage with spam callers, saving you time and frustration by wasting the caller's time instead of yours.
What Are Hiya's Features?
Hiya also focuses on spam call blocking but distinguishes itself with community-based spam detection, which aggregates data from its users globally. It can:
- Display caller ID name and call reason, giving you context before you answer the phone. (Hiya)
- Allow users to manually create block lists and manage their own spam reports, which adds a level of personalization to spam protection.

User Accessibility and Ease of Use
