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 2.32.1

• 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 transfer progress indicator.
• We fixed a bug that prevented VoiceOver from working properly with the Settings icon.
• We also fixed a bug related to image captions.

It’s an amazing app that is similar to WhatsApp but is more secure which is awesome! The only problem I have which is small but makes a difference is that when you type the last word of a sentence and click send, it doesn’t do any autocorrect on that last word. This makes it so that the whole sentence is fine except the last word is normally misspelled and when typing fast I always misspell words. WhatsApp has this feature already where it checks autocorrect on the last word before it’s sent.

Useful and secure

I find it works similar to WhatsApp but per manufacturer’s claims is more secure. I’ve had no problems with it and the only drawback I find is so few friends have this app.
