Hitokoe — One Hello

A private notebook of people you actually meet. One door for strangers, one shake for friends — and study sessions with a whisper channel.

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 it only one way: you meet in real life.

MEET SOMEONE NEW One door, two people. Show your code, they scan it — they knock, you say hello back. Both of you are present, so the answer comes now. No friend requests left hanging.

MEET AGAIN Open each other's page and shake your phones together — two hands, one moment, no buttons. The Pulse warms as you get close; on newer iPhones, precision finding points the way.

EVERY MEETING, A NEW CHAPTER A few seconds of face and voice, captured only when you're together. Either phone shoots — the moment lands in both notebooks. Years later, watch a friendship grow across meetings, voice and all.

STUDY TOGETHER, ONE SESSION Sit down to a shared study session — one clock on both phones. Earphones in, hold the mic and it's a tiny walkie-talkie: your voice lands in their ear; let go, and the channel is theirs.

SAY IT WITH A CARD Between meetings, send a card — Meet up? It's been a while — little letters that live in the notebook, not a chat that scrolls away.

PRIVATE BY DESIGN Everything lives on your two phones. No account, no cloud, no analytics. Back it up to a file whenever you like.

Learn it as a story: a hand-drawn comic of Lucky and Maya teaches the whole app in five minutes.

Hitokoe — ひとこえ — "one voice". For the people you actually meet.
