Stampo turns your postcard collection into a wall map. Photograph the front and back of each postcard, pin where it was sent from, and watch your collection come alive: a vintage world map on a warm plaster wall, every postcard scattered around it, each tied by a string to its pin. • Search any place — or drop the pin by hand • Pinch in to see exactly where each card came from • Tap a postcard to read it, front and back • A quiet hello greets you by name Stampo is small on purpose. Registration is invite-only, your collection is capped at ten cards you truly love, and there are no feeds, likes, or strangers — just your postcards, your map, your wall. No ads. No tracking. No analytics. Your photos are yours.
