Now with Listen Mode — put your phone down and follow any conversation in real time. Private, on-device translation in 18 languages. Your personal interpreter, right in your pocket Talk to anyone, in any language, using only your iPhone. LingoDuet turns your iPhone into a real-time, two-way personal interpreter, with everything running directly on your device. No internet connection. No account. No conversations leaving your phone. Simply place your iPhone between you and start talking. TWO EASY WAYS TO UNDERSTAND EACH OTHER Conversation Mode - Place your iPhone between you and the person you are speaking with. The screen splits into two sides, with the other person’s side automatically facing them. - Hold to speak, then release when you are finished. Within seconds, your words are translated and spoken aloud in their language. They can respond in exactly the same way. - Natural, face-to-face conversations without the language barrier. Listen Mode - When the other person needs to keep talking—such as a tour guide, lecturer, presenter, or shopkeeper—simply place your iPhone nearby and follow along. - Their speech and its translation appear on the screen in real time, with no buttons to press. Listen privately through your earphones, then hold to reply in your own language when it is your turn to speak. PRIVATE BY DESIGN Your voice never leaves your iPhone. Speech recognition, translation, and voice playback all run locally on your device. Nothing is uploaded, stored, or tracked. With LingoDuet, privacy is not an optional setting. It is how the app is built. WORKS WITHOUT AN INTERNET CONNECTION After downloading the required language files once, LingoDuet continues working completely offline.
