Briar Project
I've been looking for secure messengers during the last few weeks. I use WhatsApp, Signal, and Telegram. Telegram isn't very secure, WhatsApp is owned by Facebook and even Signal - while very secure - requires a cell phone number... Briar seems great in this regard but isn't available on iPhone and has no support for images, calls, voice messages, etc. Apparently they're going to support images and a desktop client, though.In short, I just don't know what to use.Edit: Session looks great but is not fully released yet: https://getsession.org/ This might be what I'm looking for in the future.
