It is not owned by a prominent tech business but by a small non-profit organization supported by donations. The app Signal allows you to host a group chat with up to 1000 individuals and a video call with up to 8 people. It is the best secure messaging app with features such as one-to-one chat, groups, stickers, photographs, file transfers, phone conversations, and even video calls. This app’s user experience is similar to WhatsApp, Facebook, Messenger, and other popular applications.
