COLLECTORS CATALOGUES
CREATE YOUR OWN MUSEUM

An app for documenting family heirlooms

Every family has a drawer of things nobody dares throw away and nobody quite remembers. The remembering is the part you can fix.

Collectors Catalogues is free on Android, works in the browser, and carries no advertising and no marketplace. Get the app → · About it

Write it down while someone still knows

The clock from the farmhouse, the ring that crossed the Atlantic, the medal nobody talks about — each gets photographs, a description, and a provenance chain recording who had it, when, and how it moved. Append-only, so the family story accumulates without being rewritten by whoever tells it last.

Honest gaps beat confident guesses

"We think it was great-grandmother's, brought from Poland" is a real record — mark it probable, write down who said so, and let a later generation firm it up. The app is built around recording uncertainty honestly rather than forcing a tidy story.

Made to be handed down

Records export freely — they are the family's, not ours. Keep everything private, or share a museum of the heirlooms with the relatives who should see it. No advertising, no marketplace, nothing for sale.
