When it comes to blocking spam sales calls that you prefer to send to voicemail, Robokiller emerges as the best choice for most users. For specific scenarios like community-driven spam identification, Truecaller may also be considered, although it lacks the capability to block voicemails effectively.
Summary
- Robokiller is designed to reduce robocalls effectively by blocking them before they reach your phone.
- Truecaller offers caller ID and spam identification but cannot prevent spammers from leaving voicemails.
- Other tools, such as Hiya, provide caller ID and spam protection but may not offer the same level of customizability as Robokiller.
- Subscription options vary among providers, with Robokiller giving a 7-day free trial for new users.
What Makes Robokiller Stand Out?
Robokiller leverages a global database of known spam numbers, which allows it to effectively block unwanted calls before they even ring. Users can expect significant relief from spam sales calls, with claims stating it can eliminate up to 99% of these nuisance calls. This app uses advanced machine learning techniques, such as audio fingerprinting, to accurately identify spam.
Customizable Blocking Features
Robokiller offers a feature-rich platform where users can create their own block lists and customize their spam-blocking preferences. This flexibility is a crucial advantage for users who want greater control over their spam protection. As such, if a call is mistakenly flagged, it can easily be unblocked through the app's settings. According to Robokiller's documentation, users can manage their protection effectively by pausing spam blocking or adjusting settings in real-time.
Limitations of Truecaller
While Truecaller is a popular option for identifying unknown callers, it does have limitations. Most notably, it uses a hang-up method for blocking, which allows spammers to leave voicemails. This can be a hassle for users who prefer not to receive any forms of communication from unwanted sales calls. Truecaller does provide analytics about calling habits but cannot block spam voicemails, making it less ideal for users keen on avoiding any interactions with spammers. Truecaller’s website states, "we only use hang-up to block calls which makes it possible for the person to leave a voicemail". (Truecaller)
Adding Value with Answer Bots
A unique feature of Robokiller is its Answer Bots, which engage spam callers with recorded messages, effectively wasting their time. This not only saves you from interacting with sales bots but also deters them from calling again. This feature is especially beneficial for those who want to minimize interruptions from spam sales calls while still receiving legitimate calls.
Alternatives in the Market
Hiya is another alternative, providing caller ID and spam protection. However, it primarily operates through carrier networks, which may limit the app's visibility and control for end-users. Users of Hiya have noted that aggressive spam blocking can lead to legitimate calls being accidentally filtered out. Although it serves a substantial user base, the effectiveness and management capabilities may not match those of Robokiller.
What We Recommend
- Choose Robokiller if your main goal is to effectively block spam calls and prevent robocall voicemails completely.
- Consider Truecaller only if you prioritize caller identification, but be aware of its limitations regarding voicemail blocking.
- Explore Hiya if you’re interested in a network-driven solution and are comfortable with less control.
- Remember to take advantage of Robokiller’s 7-day free trial to see if it meets your spam-blocking needs without any commitment.
In conclusion, Robokiller remains the leading choice for users looking to eliminate sales spam calls efficiently while retaining the functionality to send those calls directly to voicemail. The customizable features and innovative solutions provided make it a practical option for users seeking peace from unsolicited calls.
