TextSecure and RedPhone have been merged to create Signal!

Using Signal, you can communicate instantly while avoiding SMS fees, create groups so that you can chat in real time with all your friends at once, and share media or attachments all with complete privacy. The server never has access to any of your communication and never stores any of your data.

* Say Anything - Send high-quality group, text, picture, and video messages, all without SMS and MMS fees.
* Speak Freely - Make crystal-clear phone calls to people who live across town, or across the ocean, with no long-distance charges.
* Be Yourself - Signal uses your existing phone number and address book. There are no separate logins, usernames, passwords, or PINs to manage or lose.
* Stay Secure - We cannot hear your conversations or see your messages, and no one else can either. No exceptions. You can even tap and hold on a contact&#39;s name to see advanced identity verification options. Everything in Signal is always end-to-end encrypted and painstakingly engineered in order to keep your communication safe.
* Go Fast - Signal is optimized for speed without compromise. Our state-of-the-art Axolotl protocol is unmatched in its performance, strength, and reliability.
* Remain Connected - Push notifications let you know when new messages have arrived, and they&#39;ll be waiting for you even if your battery dies or you temporarily lose service.
* Get Organized - Unique archive functionality makes it easy to keep track of the conversations that matter to you right now.
* Pay Nothing - Signal is supported by a team of dedicated developers, community donations, and grants. There are no advertisements, and it doesn&#39;t cost anything to use.
* 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.
