Signal is a messaging app with privacy at its core. It is free and easy to use, with strong end-to-end encryption that keeps your communication completely private.
• Send texts, voice messages, photos, videos, GIFs, and files for free. Signal uses your phone’s data connection, so you avoid SMS and MMS fees.
• Call your friends with crystal-clear encrypted voice and video calls. Group calls supported for up to 50 people.
• Stay connected with group chats up to 1,000 people. Control who can post and manage group members with admin permission settings.
• Share image, text, and video Stories that disappear after 24 hours. Privacy settings keep you in charge of exactly who can see each Story.
• Signal is built for your privacy. We know nothing about you or who you’re talking to. Our open source Signal Protocol means that we can’t read your messages or listen to your calls. Neither can anyone else. No back doors, no data collection, no compromises.
• Signal is independent and not for profit; a different kind of tech from a different kind of organization. As a 501c3 nonprofit we are supported by your donations, not by advertisers or investors.

good app to replace whatsapp, but please please PLEASE add markdown to the text input... i know there have been considerations in the past to not implement it, but it's such a widespread feature now and it's one thing I really miss from other apps in signal. the text selection approach where you tap your modification from the popup menu is all nice and good (when it works, which isn't a given on my xiaomi 12t device), but it's so much slower than just typing the modifier characters

As a messenger app, it is great. However restoring from a backup is s disaster. I tried tu restore a backup with a verified correct passphrase, but Signal says the password is incorrect, which it isn't. I verified it. But this seems to be an issue if you look on the internet for 2 years already, but the devs at signal don't seem to prioritize this issue.

I like that it's open source, not answering to anyone. Works mostly fine. Sometimes during a video call i only see a part of the other person's picture, the rest is black screen — to fix that, I press back and then return to the call, without hanging up, without having to disrupt the conversation.

What’s new
★ We added a convenient shortcut to quickly lower your hand after you start speaking during a Signal group call. It's hands down our favorite feature in this release.
