Stereopticon

Step up to the stereoscope.

For seventy years before cinema, the whole world traveled by stereograph — twin photographs on a card that leap into three dimensions when seen through a parlor viewer. Pyramids and glaciers, world's fairs and city streets, the age of steam and the dawn of flight, all in startling depth. Stereopticon brings that lost wonder to Apple Vision Pro, exactly as it was meant to be seen: one image to each eye, in true stereoscopic 3D.

THE VAULT — OVER A THOUSAND CARDS A hand-curated library of more than 1,000 high-resolution stereographs from the Library of Congress, ready the moment you open the app. Browse an endless, fast-scrolling wall of history, or set out on a Grand Tour: Ancient Egypt, Belle Époque Paris, the American West, the Holy Land, Meiji Japan, world's fairs, the great ocean liners, and the age of flight — from Civil War observation balloons to aeroplanes over Flanders.

SEEN IN TRUE 3D Step into the stereoscope and each card floats before you in a quiet, warm-lit parlor. Stereopticon renders a separate image to each eye — real depth, not a flat picture — and pulls the archive's original master scan for breathtaking clarity. Turn the Digital Crown to blend the scene with your room.

PREPARED AUTOMATICALLY Every antique card is a little different — hand-mounted, faded, imperfectly aligned. Stereopticon trims the mount, finds the seam between the two prints, and uses on-device image analysis to correct the vertical misalignment that breaks stereo fusion. A gentle restoration lifts faded prints. It just works.

TUNE IT YOUR WAY For the enthusiast, the Curation Studio offers live alignment controls with a ghost-overlay preview — nudge depth, vertical, and split, and watch the card resolve in front of you. Save your tuning per card. Hide, favorite, and organize to taste.

SEARCH THE WORLD Beyond the Vault, search live across the Library of Congress, the Internet Archive, and Wikimedia Commons — tens of thousands more cards from collections around the globe.

KEEP WHAT YOU LOVE Export any card as a native spatial photo to your Photos library, to keep or to share.

Stereopticon collects nothing about you — no accounts, no ads, no tracking. Just you, a stereoscope, and a hundred years of the world in three dimensions.
