Rabbit Hole

A calm feed of curious things.

Full-screen cards from Wikipedia, the Met, NASA, iNaturalist, Open Library and Wikimedia Commons — picked by what you are curious about, and kept partly random on purpose, so the feed never learns how to trap you.

SIX CARDS FROM THE FEED

Every card is a whole screen

A photograph, a title, the first paragraph, and where it came from. Swipe up when you are done. Nothing counts how long you stayed.

DEEPER

The hole is the point

A senator elected three weeks after dying in a plane crash. Press Deeper and the next cards are about the widow who took his seat, the election that followed, the state he governed. Levels stack; come back up whenever you like, and the main feed is exactly where you left it.

Related cards come from the source itself where the source knows — the same artist at the Met, the same family on iNaturalist, the same author on Open Library — and from Wikipedia’s own “more like this” for the rest.

  • The Met Open Access
  • NASA APOD
  • iNaturalist
  • Open Library

Sixty per cent from the interests you pick — motorcycles, abandoned places, space, castles, caves, birds, books, films, albums, games, today in the world — and forty per cent pure chance. Wikipedia in eight languages, in any combination. Everything belongs to its authors and is shown with a link back to the source.

PRIVACY

It collects nothing

No accounts, no analytics, no crash reporting, no tracking, and nothing sent to the developer. Saved cards, settings and the taste model stay on your phone; API keys live in the iOS Keychain. To show you anything at all, the app talks straight to the public sources listed above, which see your address the way any website would.
