Stop passing one phone back and forth. With xy, each person chats on their own phone, in their own language, just like any messenger. You type or speak in yours; it shows up on their phone in theirs. The other person doesn't even need the app: show a QR code, they scan it, and the chat starts. No sign-up. Text and voice in 231 languages, with the whole conversation as context (OpenAI GPT, Google Translate as instant backup). iPhone, Android and PC.
