How it works

01

Check in

Save the area privately with one tap. Your exact coordinates are never shown or stored.

02

Leave a note

Stay for 20 seconds, then leave a little hello. Your note disappears after three days.

03

Cross again

If they checked in around the same time, your note may appear for them.

Join the private beta

A few new faces. A little hello.

Checking in

Save the area privately with one tap. Your exact coordinates are never shown or stored.

Leaving a note

Stay for 20 seconds in this beta, then leave a hello, a funny coincidence, or a little good-morning note. Your note disappears automatically after three days.

Crossing again

If they checked in around the same time, the note can appear for them. They can smile, pass, or say hello.

Your check-ins

Nobody gets to browse the places you have been.

The map

It can show that notes are around—not your exact pin, words or identity.

Your choice

A note is only a hello. The other person decides whether to answer.

Notes expire

Notes vanish after three days, and blocking is always one tap away.
