Privacy is possible. Signal makes it easy.

Using Signal, you can communicate instantly while avoiding SMS fees, create groups so that you can chat in real-time with all of your friends at once, and share media and other files with complete privacy. The server never has access to any of your communication and never stores any of your data.

• Say Anything - Signal uses an advanced end-to-end encryption protocol that provides privacy for every message every time.

• Open Source - Signal is Free and Open Source, enabling anyone to verify its security by auditing the code. Signal is the only private messenger that uses open source and peer-reviewed cryptographic protocols to keep your messages safe.

• Be Yourself - Signal uses your existing phone number and address book. There are no separate logins, usernames, passwords, or PINs to manage or lose.

• Group Chat - Signal allows you to create encrypted groups so that you can have private conversations with all of your friends at once. Not only are the messages encrypted, but the Signal server never has access to any group information like the membership list, group title, or group icon.

• Fast - The Signal protocol is designed to operate in the most constrained environment possible. Messages are delivered quickly and reliably.

• Speak Freely - Make crystal-clear voice and video calls to people who live across town, or across the ocean, with no long-distance charges.

What’s New

Version 2.37.2

• In-app notifications make it easy to see what is happening in other threads while you are using Signal. Let updates from fun conversations take you away from the boring ones.
• We improved startup performance to get you to your messages faster.
• A brand-new registration flow streamlines the setup process for first-time users.
• Conversation titles appear in bold within incoming notifications for better visibility.
• We fixed a rendering bug that sometimes caused the input toolbar to appear in the middle of the screen after using landscape mode.
• Threads with missed calls are now sorted chronologically as expected. The bug that caused those missed missed calls will not be missed.
• Simon & Garfunkel wrote a hit song about it in 1964, and now you can once again experience the sound of silence by choosing "None" as your notification ringtone in Signal.
• We fixed a crash that affected users on iOS 9.

Double Update..? (Yet Again)

Not sure whether anyone else experiences this for each and every update, but I received a notification re an update Tuesday this week, which I dutifully downloaded and then opened briefly.. I then checked in to the AppStore this morning to see if any updates are available and see the same update once more requiring download and install.

I have reported this behaviour previously and the response I received from the Devs was that this would be expected behaviour if I were on the Beta channel... but I’m not. I am however in the U.K. which is why I am especially anxious as to whether there is any less than subtle replacing of trusted binaries taking place, given one can’t exactly readily check for reproducible build and sideload having confirmed checksums...

I therefore ask again, particularly in light of further overtures in certain quarters about bypassing Signals security by circumventing authentication in group chats (for eg;) can an explanation be provided for this persistent, recurrent behaviour as lack of the same is making me question the integrity of this App.

Nice app...but

I like the fact that is anonymous and faster, but lately looks like that with the calls and photos there are some troubles, not very reliable on calls not always connect even with full internet or wifi on both phones (l tried one next to the other, on the same wifi network), and photos, taking them even directly fron the gallery or sharing from other apps, is not showing the image, so you send and send again, and after a while you will find 5/6 photos sent to the sane contact, another thing is, why can’t dekete a nessage, like in other apps (for me only or for all), l hope these bugs will be fixed soon, because l like the app and l dont want to use an app whiich is not reliabke

Excellent communications tool

Having learned that WhatsApp is owned by FB and that there are documented cases of breaches of data misuse, relieved to find a way of communicating that isn’t feeding data into the systems which are nudging our current civilisation’s behaviour, ultimately in the interests of financial gain, rather than our wellbeing.
It is a pleasant app to use. Feature-rich and well-designed.
Jaron Lanier’s book, 10 Arguments for Deleting Your Social Media Accounts Right Now makes for informative reading and for a compelling incentive to use this app as an alternative to offerings owned by the largest social media corporations.
