qoro interprets conversations between two people sitting face to face, in real time. ■ Two phones, one QR code · The other person scans the QR code on your phone with their camera and you're connected. They join in a web browser — no app needed. · Each of you speaks your own language and hears the other through translated voice and captions. ■ Or just one phone · With Solo, two people can share a single phone. ■ 70+ languages · Korean, English, Japanese, Chinese, Spanish, Vietnamese and more than 70 languages in all. ■ qoro view — snap to translate · Take a photo of a menu, sign or document, or open a file, and see it as an image in your language. · Save translated images to Photos. ■ History · Interpreted conversations are kept as original and translated text. Export them as a text file or delete them. · Voice is never stored. ■ Credits · Interpreting uses credits (Q). 1 Q is one minute of interpreting, and credits are used only while interpreting is running. A qoro view translation uses 1 Q. · When you invite someone, their usage comes out of the room creator's credits. · Credits are topped up with App Store payments. ※ Interpretation and qoro view translation are processed by Google's AI (Gemini). The app asks for your consent before first use. ※ AI interpretation can be wrong. Check important matters, such as medical, legal or contractual ones, with a professional. ※ You must be 14 or older to use qoro.
