Hi everyone. I'm Angelfrieren, the maker of OnceChat. This started with a feeling I couldn't shake. Texting my friends, I'd often feel the conversation getting too long — and quietly end it. But then, with no messages at all, I'd feel lonely. I wanted the connection, yet starting a conversation felt strangely heavy. "Do I really want to talk that much?" — and still, I wanted to stay close. once chat is my answer to that contradiction. One message a day, each. You send today, they send tomorrow — taking turns. Every message disappears in 24 hours. No long threads to keep up with, no pressure to reply fast. Just one quiet word a day, with someone who matters. I'm a student building this solo. And quietly, I hope a messaging app from Japan can reach people around the world. I'd love to hear what you think
