Communication apps are software applications designed to facilitate conversations and information sharing between users. They allow people to send text messages, make voice and video calls, and share files instantly over the internet. Popular examples include WhatsApp, Facebook Messenger, and Zoom, which cater to both personal and professional communication needs. These apps often include features like group chats, emojis, and stickers to enhance interactions. Many also offer end-to-end encryption for privacy, ensuring that messages remain secure. With the rise of remote work and global connectivity, communication apps have become essential tools for staying in touch with friends, family, and colleagues.
