Signal - A Messaging App
Signal is a messaging app known for its focus on privacy and security. Here are some of its key features:
End-to-End Encryption: All messages, calls, and media are encrypted end-to-end, ensuring that only you and the recipient can read or hear them.
Private Conversations: Start a private conversation with one or more contacts, with messages disappearing after a set time.
Group Chats: Create groups for messaging with multiple contacts, with the same level of encryption as private conversations.
Voice and Video Calls: Make secure voice and video calls to other Signal users.
File Sharing: Share photos, videos, documents, and other files with contacts.
