In today's digital age, unwanted calls and spam messages are a significant nuisance. To combat this, several call blocking solutions are available, including Apple's built-in call blocking feature, Nomorobo, and Robokiller. This article provides a detailed comparison to help you determine the most suitable option for your needs.
What is Apple's Built-in Call Blocking Feature?
Apple offers a native call blocking feature integrated into iOS devices. This functionality allows users to block specific numbers and identify potential spam calls. However, it relies on third-party apps to provide a comprehensive spam call blocking experience.
How Does Nomorobo Work?
Nomorobo is a third-party app designed to block robocalls, telemarketers, and spam texts. It maintains a database of known robocallers and uses this information to identify and block unwanted calls. Users can choose between two modes:
-
Identified Mode: Robocalls ring through, but the caller ID displays "Robocall," allowing users to decide whether to answer.
-
Blocked Mode: Robocalls are sent directly to voicemail without ringing.
Nomorobo is available for iPhone and Android devices, with a free version for landlines and paid subscriptions for mobile devices. (nomorobo.com)
What is Robokiller?
Robokiller is a call blocking app that aims to eliminate up to 99% of spam calls and texts. It utilizes a global database of over 1.4 billion analyzed calls to protect users from known phone scams. Robokiller employs patented audio fingerprinting technology and machine learning to identify and block unwanted calls. Additionally, it offers "Answer Bots," which engage robocallers with pre-recorded messages, wasting their time and providing users with "Robocall Revenge." (apps.apple.com)
