One proposal. One decision. More time with the people who matter.
Ittsui picks the place and the time. You confirm in one tap.
Ittsui (一対): the art of tending the bond between two people.
This is the proposal Ittsui would send. Swipe the card, swap the place, or confirm: it works exactly like the app.
Why not just send a message?
Arranging a coffee with a friend rarely takes one message. It takes twelve, over four days, and often it never happens.
It's not that you don't want to.
It's the workload and the lack of time that make us lose sight of the people who matter, without ever deciding to. Ittsui makes the decision for you each week; you just say yes.
How it works.
- 01
1 proposal a week
Each week, get a single proposal (a real place, a time) ready to confirm in one tap.

Your guest replies in one tap
They get a link by SMS or WhatsApp, see the place and the time, and tap “I'm in”. Nothing to negotiate.
The problem isn't wanting to.
It's time.
“The problem isn't that we don't want to see people. It's that we don't have the time.”
A sentence overheard by chance, one evening while travelling, that gave Ittsui its current shape: one proposal, one decision, then nothing left to manage until next time.
