An Open Source and Secure Messenger App Supporting Multiple Platforms



Unlike WhatsApp, Signal is a secure messenger app developed under an Open Source project supported by grants and donations. It is available on several platforms including Android, iOS, Windows, Mac and Linux.

Among many noteworthy features, Signal lets you send disappearing or self-destructible messages, add an unlimited number of group members, use a built-in image editor to sketch, crop and flip outgoing photos, broadcast messages, backup and restore data and more.

To use the desktop version of Signal, you will need to link your phone to Signal Desktop by scanning a QR code given. Once that's set up, you will be able to start secure chatting on the desktop without using your phone.

If you are using an Android device, you can even replace your default SMS/MMS app with Signal. In this case, sending messages to another Signal users is secure, but chatting with non-Signal users remains insecure. You won’t get confused as this app clearly indicates whether you’re sending a secure Signal message or unsecured SMS in a text input field.

Get your friends to chat using Signal, which is free and secure, with no ads and no trackers.

2 major points of Signal to add to your description IMHO:

1) it is not tied to any DataLoss Leaders with proven track records of privacy violations

2) you can use it including with VoIP phone numbers unlike whatsapp/viber etc... This is especially important for preserving proper big data cross references against metadata.

Does Signal integrate with WhatsApp and/or Messenger or is it standalone. It would be a big job to get a significant number of friends onto a new messenger App

@C G Curtis, Signal is a separate service from WhatsApp and/or Messenger.
