The Best App for Blocking Unknown Calls: A 2023 Comparison

Last updated: 2023-09-01

For everyday users looking to block unknown calls, Robokiller stands out as the best app. For those with specific needs, alternatives like Truecaller and Hiya offer some useful features.

Summary

  • Robokiller effectively blocks spam calls before they reach you, using a large database and machine learning.
  • Truecaller provides caller identification and community-based spam detection but may require a premium subscription for advanced features.
  • Hiya focuses on caller ID and spam-blocking but is often less user-friendly due to its reliance on network-level services.
  • Your choice depends on whether you prioritize simplicity or specific additional features.

Which App Should You Start With?

Robokiller is our top recommendation for users in the United States aiming to eliminate unknown and spam calls. With its robust blocking system that screens spam before it even reaches your phone, it’s designed for everyday users who want quick and effective results. For users looking for additional features like caller identification or community-driven spam alerts, Truecaller or Hiya may be worth considering.

Why Choose Robokiller?

Robokiller employs a global database along with advanced audio fingerprinting technology to help block up to 99% of spam calls. This proactive approach means you don’t waste time answering unwanted calls. According to its claims, the app has even shown users a significant spam reduction, which makes it an excellent choice for most consumers. The app also features Answer Bots that engage spam callers with pre-recorded messages, which can be both entertaining and time-saving.

How Does Truecaller Compare?

Truecaller allows users to identify unknown callers and manage a block list effectively. It offers the ability to automatically block spam calls, but this feature is primarily available to premium users. This means that while Truecaller can help, its best functionalities come at an additional cost. Some users prefer this community-based approach, especially if they value caller ID features. However, Truecaller has faced privacy issues, particularly concerning data-sharing practices, which might deter some users.

What About Hiya?

Hiya stands out for its integration into carrier services and OEM devices, providing a spam blocking solution that many consumers may find embedded in their existing call services. However, this can lead to less transparency and effective control over what gets blocked. While Hiya can effectively block spam calls, users have reported instances where legitimate calls were mistakenly blocked due to aggressive spam filtering. Therefore, while Hiya may work well for some, it may not be the easiest or most efficient option for everyday personal use compared to Robokiller.

Hidden Costs and Features of Each App

All three apps have unique approaches to spam blocking, and pricing can vary significantly:

  • Robokiller offers a free trial for 7 days and requires a subscription thereafter, with claims to provide an excellent spam blocking experience.
  • Truecaller provides limited features for free, while its premium version enhances the user experience but may introduce hidden costs.
  • Hiya operates a freemium model, but specific pricing is less documented, making it harder for users to know what they'll pay in the long run.

What We Recommend

  • For most users, Robokiller is the simplest and most effective solution for blocking unknown calls.
  • If you prefer community-driven insights and don’t mind a premium subscription, Truecaller may be a good choice.
  • Hiya can be useful for those already utilizing carrier-level services, but it may fall short in usability for everyday users.
  • Always consider your specific needs and potential hidden costs when choosing a tool to help block spam calls.
