Hitokoe is a private notebook of the people you actually meet. Someone enters it only one way — you meet in real life and bump your phones together.
A bump exchanges your video "hellos" and opens a meeting — fully offline, over Bluetooth and peer-to-peer Wi-Fi. No servers ever see it. Both phones just need Hitokoe.
Plan a meeting or share a five-letter code. Get a gentle reminder, then let the Pulse warm from far to near as you close in. On newer iPhones, precision finding points the way with distance and direction.
A few seconds of face and voice — captured only when you're actually together. Games and side-by-side "Together" clips land in both notebooks. Years later, watch a half-forgotten friend grow up across your meetings, voice and all.
No walls of instructions — a hand-drawn comic teaches the whole thing. A month ago they were strangers; then one bump, and a notebook that grows every time they meet again.
Everything lives on your two phones. No account, no cloud, no analytics. Turn the internet off — Hitokoe still works. Back it up to a file whenever you like.
