Yonora is a simple messenger for the people who matter to you. Messages, voice notes, photos, video, and free voice and video calls — all in one app. PRIVATE WHEN YOU WANT IT Open any one-to-one chat, tap the lock, and Private mode turns on. From that moment your messages are end-to-end encrypted on your own devices, so only the two of you can read them. Nobody else can — not even us. SPEAK YOUR OWN LANGUAGE Write in the language you think in. Yonora translates messages into the language the other person reads, across a hundred languages. Send a voice note and it can be turned into text, or into another language, so family in different countries can finally talk without stopping to type in English. FREE VOICE AND VIDEO CALLS Clear one-to-one calls and group calls for the whole family or the whole team. Put a call on hold and switch to another one. Calls use your internet connection. EVERYTHING YOU EXPECT FROM A MESSENGER - Groups, with disappearing messages when you want them - Voice messages, photos, videos and large files - Polls, events and live location sharing - Moments — share a picture or a line with your contacts for a day - Write a message now and let it send on the day you choose - Star and save the messages you want to keep - Read receipts, typing, and who is online — all switchable YOU DECIDE WHO SEES WHAT Every privacy switch is in one place. Choose who can see your last seen, your profile picture, your About, your phone number, and who can add you to groups. Lock individual chats behind your passcode. Turn on screenshot protection and, where your iPhone allows it, screenshots and screen recordings of Yonora come out black; if a screenshot is taken while protection is off, you are told in the chat. FIND ME WITHOUT MY NUMBER Set a public @username or share your QR code, and people can reach you without ever knowing your phone number. YONORA AI, BUILT IN Ask Yonora anything. Summarise a long chat in one line. Rewrite a message before you send it so it says what you meant. Get a suggested reply and answer in one tap. Reply automatically while you are busy. AI answers can be wrong, and there is a Report button on every one of them. SAFE AND RESPECTFUL Block anyone, in one tap — they cannot message you, call you, or see when you are online. Report a message or an account and a real person reviews it. You can delete your account, and everything in it, from inside the app at any time. WORKS WHERE YOU DO Yonora also runs in your browser, so the same conversations follow you from your phone to your computer. Yonora is made by Yonora LLC in Maryland, USA.
