One button for your language, one for theirs. Hold to speak, release to send. You run both sides of the conversation from a single phone.
Natural speech-to-speech that follows the speaker's own voice. No typing, no reading a script, no teaching anyone the app.
Your words, in their language, rotate to face the person opposite you. Their reply stays upright for you to read.
Cross a border and Psybeam suggests the local language from your location, so you start talking instead of digging through menus.
Start with free minutes, then buy a pack only when you need more. No recurring charge and no trial trap.
Audio is streamed to OpenAI only to translate it, never stored and never used to train models. Your transcript stays on your phone.
