Signal iOS

Signal is a free, open source, messaging app for simple private communication with friends. Say "hello" to a different way of chatting: Signal is all about privacy, but with all the features you expect from a chat app. State-of-the-art end-to-end encryption (backed by Signal's open source protocol) keeps your chats safe. Neither we can read your messages or listen to your calls, nor anyone else. Privacy is not an optional mode, it is how Signal works. In all your messages, all your calls, forever. Send and receive messages, voice memos, photos, videos, GIFs and files for free. Signal uses your phone's data connection so no SMS or MMS charges are incurred. Make crystal clear calls and video calls to people who live across town or across the ocean with no long distance charges. Add a new layer of expression to your chats with encrypted trading cards. You can also create and share your own sticker packs.
