What is Signal?
Using Signal, you can communicate instantly with your relatives without making a compromise on privacy or security. Make video calls, send messages, pictures, videos, documents, voice recordings, GIFs, contacts & location, create groups so that you can chat in real time with all your friends at once and react to their messages with emojis -all with complete privacy-. Signal servers never have access to any of your communications and never store any of your data.
- Say Anything - Share text, voice messages, photos, videos, GIFs and files for free. Signal uses your phone's data connection so you can avoid SMS and MMS fees.
- Speak Freely - Make crystal-clear voice and video calls to people who live across town, or across the ocean, with no long-distance charges.
- Make Privacy Stick - Add a new layer of expression to your conversations with encrypted stickers. You can also create and share your own sticker packs.
- Get Together with Groups - Group chats make it easy to stay connected to your family, friends, and coworkers.
- No ads. No trackers. No kidding. - There are no ads, no affiliate marketers, and no creepy tracking in Signal. So focus on sharing the moments that matter with the people who matter to you.
- Remain Connected - Push notifications let you know when new messages have arrived, and they'll be waiting for you even if your battery dies or you temporarily lose service.
- View Source - All of our code is free, open, and available on GitHub (https://github.com/signalapp).
- Join Movements - Technology developed by Open Whisper Systems is trusted and used by millions of people around the world every day.

alexandre_guillet thinks Session is an alternative to Signal
LinuxDoge thinks Element is an alternative to SignalNo phone number. You can choose a good server, but communicate with all. You can run it over Tor. The app is easy to use but full of features, that Signal still dreams of. There are Apps for every platform, in every Form.
I love Signal because of the automatic end-to-end encryption. Even though Whatsapp now has that, too, I still prefer Signal because it's more transparent about key handling. I would love them to add an opportunity to use it without a phone number. This is the only thing I don't like because you can't stay anonymous when using Signal.
I have never heard about it! But i'm gonna try it

This app got a 100% rating on the EFF's Secure Messaging Scorecard.
WhatsApp and Telegram are not completely open and are not as secure as Signal!
Regardless of who endorses him, Moxie is hostile to anyone that threatens his control over the project. He also has a very high opinion of the Google Play store despite that coming with Google's ToS and Google Play Services. He does everything he can to shutdown alternative modes of distribution. I would read this before installing and contributing to Signal's userbase, especially if open source and/or F-Droid are things you care about.
I am not an expert but i appreciate the thought that you put into your criticism. Most importantly i appreciate the alternatives that you listed. I'm checking into Tox right now.

It is the best, no doubt about that. But be aware, if you need to reset your smartphone you will loss all your old chats. Be aware! In order to preserve your chats install Signal in your desktop, laptop, tablet and backup. Remember Signal is not able to read the user messages, so not even ask.

I was satisfied with it, but now that they will be removing SMS functionality there is a good chance I will be looking for something else.
One thing for sure is that I will stop recommending Signal to friends and family. SMS integration was very useful to most of them also. They are not going to be happy that I once recommended Signal to them.
CIA connection, not private as it love to advertise. Good alternative to SMS apps at most tho, interface is good.
