Nomorobo and Robokiller: A Comparison

Nomorobo and Robokiller are two of the most popular mobile spam blocking apps on the market. While these two apps share a common goal of blocking spam, the apps do feature some differences, and the proper choice for you may depend on those differences.

This guide offers insight into the pros and cons of Nomorobo and Robokiller, as well as the situations where one is a better choice than the other.

What is Nomorobo?

Nomorobo is a spam call and blocking service designed to protect users from unwanted phone calls, robocalls and telemarketing calls and texts. It works by identifying and silencing them before they reach your phone, whether it is a landline or mobile phone. Nomorobo uses a database of known robocaller numbers and algorithms to identify and block incoming calls from spam callers.

Pros of Nomorobo

• Effective Robocall Blocking: Nomorobo is able to effectively block robocalls and telemarketing calls by leveraging a large database of known spam numbers and call screening capabilities
• Voicemail Analysis: Nomorobo’s voicemail analysis service adds an extra layer of protection by screening recorded messages.
• Adaptable to New Spam Numbers: While it may not catch brand new spam numbers immediately, the system adapts quickly as its database expands.
• Whitelisting Options: Users can whitelist important numbers to prevent accidental locking
• Cost: Nomorobo only costs $1.99 a month, which makes it a cheaper option than Robokiller

Cons of Nomorobo

• Legitimate Calls May Be Blocked: While Nomorobo aims to block robocalls , there is a risk of it incorrectly identifying and blocking legitimate calls, especially if the caller’s number is spoofed
• Lacks Interactive Features: Unlike Robokiller, which has answer bots that waste scammers’ time, Nomorobo just blocks the calls that come in
• Has Limited Compatibility: Nomorobo primarily works with VoIP (Voice over Internet Protocol) landlines, which means it is not suitable for traditional landlines or cell phones

What is Robokiller?

Robokiller is a spam call and text blocking app that uses advanced spam detection algorithms to identify and block unwanted calls and text before they reach you, it offers features such as “answer bots” to waste scammers time. This app continuously updates its spam call database, allows users to customize their call-blocking settings, and provides a visual voicemail feature so you can review intercepted calls. Robokiller is a subscription-based service and is not compatible with Landlines.

Pros Of Robokiller

• Effective Spam Blocking: Robokiller uses predictive analysis and audio fingerprinting to identify and block spam calls and texts, potentially saving users from annoying and potentially fraudulent calls
• Peace of Mind: By blocking spam calls, Robokiller can reduce the stress and anxiety associated with dealing with unwanted calls and texts
• Comprehensive Protection: Robokiller offers protection from both voice and SMS-based fraud attempts
• Spam Control: Users can report spam calls to help train the Robokiller algorithm and improve its effectiveness
• Answer Bot: Users can choose to have answer bots hassle any robo callers that attempt to contact you

Cons of Robokiller

• Monthly Subscription Fee: Robokiller has a free seven-day trial. After that, it cost about $4.99/month or $39.99/year, and some users feel it is too much for a call blocker
• False Positives: Some users have reported that Robokiller can incorrectly identify legitimate calls as spam, leading to missed calls
• Overly Aggressive Blocking: In some cases, Robokiller can block calls from numbers that are not in the user’s contact list, even if they are not spam

Situations When Nomorobo is the Better Option

Nomorobo will be more beneficial than Robokiller in situations where the user is using VoIP landline and needs robocall protection as it is one of the few services that supports landlines which is something Robokiller does not offer. It is also free for landline users, making it a more cost effective option.

Additionally, Nomorobo provides a simpler and less invasive call-blocking experience by screening calls with a single ring before blocking them, whereas Robokiller uses answer bots that some users may find intrusive.

Situations When Robokiller is the Better Option

Robokiller will be beneficial for your personal devices, as it offers essential spam-blocking features to iPhones and Androids on all carriers throughout the United States and Canada. It's notable compared to Nomorobo, which specializes in blocking spam calls to landlines. Nomorobo will cover Iphone and Android on various phone companies but at an extra cost (Nomorobo Basic and Nomorobo Max).
