The offline social notebook. People enter it only one way: you meet in real life and bump phones. Nobody stays a stranger. Hitokoe is a private notebook of the people you actually meet. No follows, no feed, no likes, no accounts. Someone enters your notebook only one way: you meet in real life and BUMP your phones together. MEET → BUMP → LEAVE A MOMENT → MEET AGAIN • BUMP — hold two phones together and you exchange your video "hellos". Works fully offline (Bluetooth + peer-to-peer Wi-Fi). Both phones need Hitokoe. • MOMENTS — a few seconds of face and voice, captured only when you're actually together. Each meeting becomes a new chapter of that person. • TOGETHER — press two phones edge-to-edge and record one wide panorama, half from each camera. One tap starts both. • KEEPSAKES — record a clip for someone now, hand it over at your next bump. • MEET UP — plan a meeting or share a 5-letter code, get a gentle reminder, then let the Pulse guide you to each other when you arrive. On newer iPhones, precision finding shows distance and direction. • YEARS LATER — open the notebook and watch a half-forgotten friend grow up across your meetings, voice and all. PRIVATE BY DESIGN Everything lives on your two phones. No account, no cloud, no analytics. Turn the internet off — Hitokoe still works. Back up to a zip file whenever you like. Hitokoe — ひとこえ — "one voice". The offline social network for people who actually meet.
