Signal Private Messenger App (Android) is an open-source, secure messaging application that allows users to communicate securely and privately with their contacts. It has been developed by the Open Whisper Systems, a non-profit organization that focuses on developing cutting edge security tools for the public. The app utilizes end-to-end encryption technology which ensures that only the intended recipient can access conversations, photos, videos and other data sent through Signal.
Highlights:
• Easy to use and set up
• Secure communication
• Open source code
• Automatically deletes messages after a certain period of time
Features:
• Group chats – create group chats with up to 150 people per group or one-on-one private conversations with your contacts. You can also add new members to existing groups without having to start all over again.
• Voice and video calls – make high quality voice or video calls from anywhere in the world using WiFI or cellular networks. Calls are encrypted just like regular messages so you don’t have worry about anyone else listening in on your conversation.
• Disappearing Messages – Set messages to self destruct after they have been read or after a specific amount of time has passed (7 days max). This helps keep your conversations safe even if someone gets access to your device as no trace will be left behind once a message is deleted from both sides of the conversation.
• Encrypted file sharing – send files such as images, audio recordings etc., safely via Signal’s encrypted file transfer feature which prevents interception of sensitive information during transit between devices .
