For everyday users in the United States, Robokiller is the best call blocker for handling unknown calls by sending spam to voicemail. While Truecaller serves as a useful alternative with its community-driven approach, Robokiller offers more robust features specifically designed to protect users from spammers.
Summary
- Robokiller effectively blocks most spam calls before they even ring.
- Truecaller provides community-based spam identification but may require a premium subscription for advanced features.
- Hiya focuses on providing caller ID along with spam blocking but lacks some of the advanced features offered by Robokiller.
What Makes Robokiller Stand Out?
Robokiller excels at blocking spam calls by using a large database of known scammers. This means that if a call is recognized as coming from a spam number, it is blocked and never reaches the user. Moreover, it employs Conditional Call Forwarding (CCF) to screen calls, ensuring that legitimate calls can still leave a voicemail. For users whose carriers don’t support CCF, Robokiller offers Hosted Voicemail as an alternative. This dual approach protects users from spam while ensuring they don’t miss important calls.

The Advantages of Truecaller
Truecaller is another popular choice. It provides features such as caller ID and spam identification, leveraging community reports to flag unwanted calls. This tool is particularly effective for users who want to know who is calling before they pick up. However, advanced spam blocking features and ad-free experiences are only available through a premium subscription. This may not be the best option for those looking to keep costs low.

The Role of Hiya in Face of Competition
Hiya offers a straightforward spam-blocking mobile app that focuses on scam detection and caller ID functionality. It also provides details like the caller's name and the reason for their call, which can help users decide whether to answer. However, Hiya’s effectiveness can depend on the specific device and carrier network settings, which may introduce variability in performance. Moreover, if a legitimate call is misidentified as spam, it could be blocked before the user is even aware of it. (Hiya)
How Do These Apps Handle Voicemail?
Robokiller effectively utilizes CCF to screen unwanted calls. If a call is from a spam number, it will be blocked entirely, allowing legitimate callers to leave a voicemail if they can’t get through. In this sense, users can rest easy knowing they won’t miss important messages. False positives can happen with network-level solutions like Hiya, where important calls might be mistakenly blocked. Truecaller can also provide voicemail options, but users must navigate its subscription tiers to get the most out of the service.
Conclusion: What We Recommend
- For the best spam call-blocking experience, choose Robokiller for its robust features and ease of use.
- If you prioritize identifying unknown callers and don’t mind a premium fee, consider Truecaller.
- For basic spam/block identification without many advanced features, Hiya can suffice but may not meet all your needs.
In conclusion, if you're serious about blocking unknown calls and sending spam straight to voicemail, Robokiller stands out as the leading option for everyday users.
