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 2.32.0

• Optional support for Typing Indicators. The dots between the lines help you read between the lines.
• We revamped Signal's sending logic to improve performance in poor network conditions. Step into that top-floor elevator and lose reception with confidence, because the number of times that you'll need to manually retry is also going down.
• Signal now looks better than ever on the iPhone XS Max and iPhone XR.
• Take advantage of the new landscape media support. Turn your phone sideways while viewing pictures and videos. Be rebellious and watch a portrait video in landscape if you have fallen in love with videos that don't use your entire screen.
• Watch as your media uploads and downloads come full circle with the new file transfer progress indicator.
• We fixed a bug that prevented VoiceOver from working properly with the Settings icon.

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.

Love it

This app is brilliant. Recent happenings in the social media world have pushed me away from using their platforms, and other occurrences in the part of the world that I live mean that the alternatives to Signal no longer work due to VOIP blocking. This gets around it and I'm grateful that I can continue to live a semi-normal life and communicate with my family beyond the political bordera. I absolutely recommend this app over all others. Thank you to the signal team, I hope you understand just how important private, free, and accessible communication is in this world, and to me.

More writing space please

Signal is faultless in typed operation- sorry not used speak: have just noticed this in updater message and I need the invitation to Signal again to my son who manages our family group in WhatsApp. I want to get away from Facebook owners.
Please give us more than four lines of typing space between keyboard and last message. I need to see more of my own words - whereas I can scroll up to previous messages. Stopped Twitter account.
