Binary Star operates two products in shared orbit — a collectible-card platform and a receipt-first budgeting app — built by the two people who use them daily.
Turn your photos into limited-edition collectible cards — issue, share, and build a collection that's yours alone.
PodKitty turns your receipts into a line-item ledger. Scan, track every item, share categories with your household, and earn rewards.
Like a binary star, two independent products orbit one center of mass: an obsession with software people actually keep on their home screen.
