Cards you play, cards that know you

The feed is the homepage, and that's deliberate. Swapp is invite-first while we grow, so you sign in at the door — but once you are in, the first card is already playable; the product is the pitch, the way it is on the apps you actually use. Games, decks, books, challenges: one swipe each. (A shared card link is the open door — it plays instantly for anyone.)

What makes the feed different isn't on the screen. Every interaction — a page turned, a round played, an answer given — becomes a statement in an immutable behavioral ledger. Not "you opened the app," but what you actually did, at the resolution it happened.

That record is what lets the feed learn you honestly. Difficulty comes from how everyone actually performed, not a designer's guess. What you see next comes from what you've done, not what an advertiser paid for. Your progress is a number with a paper trail.

You can play as a guest forever. If you make an account, your guest history comes with you — the ledger doesn't forget, and it doesn't start over.

The substrate underneath is Empress, and it's the other half of the story: the same ledger this feed runs on is behavioral infrastructure any builder will be able to rent. Swapp is the proof it works at consumer speed.
