In an age where privacy has become a rare commodity, a champion rises to protect your communication. Enter the Signal app, a messaging service designed to prioritize your privacy and security. This comprehensive review will navigate you through its unique features, setup process, and performance,...


  • Strong encryption – Messages are encrypted end-to-end using open-source cryptography for maximum security and privacy.
  • Open source code – As an open source project, Signal’s code can be inspected and audited by independent experts.
  • Non-profit backing – Developed and supported by a non-profit organization rather than a private company.
  • Free to use – Signal is free with no advertising, subscription fees, or selling of user data.
    Minimal metadata – Signal minimizes the metadata collected compared to other messaging apps.


  • Limited features – Signal has fewer features than more full-featured messenger apps like WhatsApp or Telegram. Voice and video calls are available, but no stories, stickers, chat bots, etc.
  • Contacts needed – Can only message other Signal users, requiring contacts to install Signal, too.
  • Setup difficulty – The encryption protocols can make the initial setup more difficult compared to less secure apps.
  • SMS support issues – SMS support is limited and can be unreliable compared to dedicated SMS apps.
    Desktop app bugs – The desktop app has had some buggy experiences reported.
