Spotted a mistake in a card?

Every card is reviewed by a person and links to its source, but mistakes happen. Email us with the card's title and what looks wrong, and we'll check it against the source and fix it.

Common questions

Why does the feed end? On purpose. Curio shows a set of cards, then lets you review what you learned instead of scrolling forever. Tap "Load a fresh set" for more.

How do I save a card? Double-tap it, or tap Save on the right.

Do I need an account? No. Everything you save stays on your phone.

No new cards? Open Explore and tap refresh in the Library panel. Curio needs an internet connection to download new cards, but works offline after that.
