After a more detailed study of the program, I was surprised and happily found the same settings in the slider, which allows screen shots (thanks for that developers). The problem of describing the application somehow understood.

Now the interface. It is spartan and a bit like Facebook Messenger. In the bottom right of the screen is the key to activate the chat. As mentioned above, in the messenger communication occurs only within the system, that is, your partner must leave the room at Signal. Actually, according to him, it is necessary and contact.

in addition, the application provides a built-in search for a subscriber, it is possible to organize a group (group chat, who immediately is in the protected mode) .

Among the other features – Import SMS database system, that is, the program is ready to take under his wing before unencrypted messages. You can also create an encrypted backup “esemesok” and shared in the same restore (on the chat it does not apply, excluding any possibility to crack the conversation).

Security Overview options


Signal application can be used to work with the default SMS. This activates the forced request for delivery of each message sent (does not work with all operators), and also includes support for sending SMS and MMS messages via Wi-Fi.
