Signal – a messaging app for simple private communication with friends. Signal uses your phone’s data connection (WiFi/3G/4G) to communicate securely, optionally supports plain SMS/MMS to function as a unified messenger, and can also encrypt the stored messages on your phone.
– Conversations: long conversations with friends, regardless of where you live. Signal provides a very useful function of voice calls.
– Group chat: allows you to create encrypted groups, so we can have private conversations with all your friends at once. In this case, both the encrypted messages and the signal server do not have access to any group data such as the members list, title and group icon.
– Sending SMSs: allows you to send free SMS and MMS, but you must have an active internet connection to use this service. In addition, we can set notifications of new messages in the status bar, there is also the option of setting the Enter key to send messages directly.
– Communication history: users have quick access to communication history, which is displayed as a scrolling list.
The application is developed by the Signal Foundation and Signal Messenger LLC under the GNU GPL 3 license.
