Summary

  • Robokiller blocks spam calls before they ring, using a vast database of known scammers.
  • Truecaller provides caller ID features that can identify unknown numbers in real-time.

What Are the Features Offered by Robokiller?

Robokiller excels in providing spam call protection and SMS filtering. Its standout features include:

  • Spam Call Blocking: Blocks calls from known scammers, ensuring they never reach you. If recognized as a scam call, it won’t ring through. (Robokiller)
  • Text Message Blocking: It provides spam text blocking, actively filtering out unwanted messages.
  • Answer Bots: This feature routes spam calls to pre-recorded messages, wasting the scammers' time instead of yours. This unique approach not only protects users but also engages spammers differently. (apps.apple.com)
