Texting apps are software applications that allow users to send and receive text messages over the internet. These apps often provide additional features such as voice calls, video calls, and multimedia sharing, making communication more versatile. Popular examples include WhatsApp, Telegram, and Signal. Most texting apps require an internet connection, either through Wi-Fi or mobile data, to function. They typically use end-to-end encryption to enhance privacy and security, ensuring that only the sender and recipient can read the messages. This makes them a popular choice for both personal and professional communication.
