Dear friend,
this will take
a while.

Pigeon is a pen-pal app where letters take real time to arrive — the farther the friend, the longer the wait. Handwritten feeling, real postmarks.

The long way

Distance is
part of the letter.

Every letter travels for a time set by the distance between you and your pen pal — minutes for a neighbour, days for the other side of the world. It's enforced on the server, so nobody can peek early.

In the post
Postcards, not bubbles

Every letter
wears a stamp.

The sender's country as a stamp, a postmark, words that took their time to get here. No typing dots — you read it when it lands.

Private by design

Only the
two of you.

Your letters can only be read by you and your pen pal, and only once they've arrived. Block or report anyone; the moderation tools can't open private letters.
