It has most popular messaging and social functions: - Chat (supports text, emoji, voice, photo, video, file, card, supports group chat, supports offline messaging) - Voice/Video Call (supports group call) - Collection & Note - Channel Moreover, it provides some useful privacy protection functions: - Message Self-destruction - Message Recall - Contact/Chat Lock

Tired of phone calls? Tangle replaces them by turning texting into a focused, real-time chat that starts and ends just like a call. Send a time-limited invite, chat with guaranteed focus, and hang up to erase the chat for everyone. End-to-end encryption and privacy by design keep conversations private even from us. WHY TANGLE Unlike regular texting that leaves you guessing if someone's there, or calls that demand immediate voice attention, Tangle gives you guaranteed focus without the pressure. You get real presence confirmation and immediate attention like a call, but with text-only communication that is perfect for loud places or when voice isn't ideal. Need a quick answer during a chat? Ask Tangle is your privacy-first AI assistant built right into conversations. Send your question and get instant, intelligent responses with optional live search for real-time information. Your question goes to the AI, but zero chat history or personal data goes with it. Answers arrive encrypted in the chat like every message, and everyone sees the response together. Built for real-life moments: making dinner plans in 2 minutes instead of 20, working alongside someone without constant interruption, having real conversations without wondering if they're multitasking, or checking that your partner got home. Sometimes you just want to connect and know someone is really there. Zero digital clutter. When you hang up, messages vanish everywhere, no endless histories cluttering your phone or living on servers. You control who joins with unanimous consent for changes. Privacy that actually works: burner tags you can change anytime, plus end-to-end encryption where even we can't read your messages. HOW IT WORKS Send a time-limited invite to up to 3 people. They answer to join, and presence indicators show who's actively in the chat as you talk. If everyone is away for over a minute, the chat wraps up naturally. There's also a Focus mode for time-sensitive chats where everyone needs to stay locked in. Need to add someone or take a break? Propose it and everyone votes. Any single "no" cancels the change. Hang up to end the session and messages disappear for everyone. Only a lightweight record remains in your History, where you can long-press any entry to block or report. Manage blocked contacts in Profile, Privacy and Support. Create scheduled chats (one time or recurring) from Action Center, Schedule. Start group conversations from Action Center, Group. Switch to burner mode or update your temporary tag from Action Center, Burner. Everything is designed for quick access when you need it. CONSENT AND SAFETY Nothing changes unless everyone agrees, including adding people or pausing. Any single no stops it. You can block or report by long pressing any conversation in your History page. Blocks apply to the account permanently, so changing their main tag or burner tag will not help someone evade a block. Change or delete your burner tag anytime to instantly cut off contact. Choose who can invite you: Anyone, Contacts Only, or Nobody in your privacy settings. We collect minimal data. Only lightweight chat history records showing who connected and when, never message content. Tangle is privacy first with end to end encryption and zero knowledge of your conversations. NOTES FOR iOS Live Activity invites can appear on the Lock Screen for quick join. To auto-dismiss the Live Activity if you miss it, allow Live Activities on the lock screen. Notifications are required to receive invites on time. Certain technologies and processes used in Tangle are patent pending.
