card swipes become tally strokes on a map of your city. skip a spot, peel a sticker. dare a friend, loser buys.
every card swipe drops a mark on the shop where it happened. four strokes, then a strike. the map fills in as you live.

connect once. we keep the ledger, five strokes at a time. skip a spot and the sheet notices: a sticker peels.

friends see your strokes, never your dollars. the one who slips owes the round.

read-only bank link. friends see counts, never amounts. delete everything in one tap.
