Invite-only

The card + wax tracker built for collectors.

Track singles, sealed wax, and the breaks that connect them. CardYield is the only app that knows what a break actually cost you, from the case down to every single that came out of it.

The wedge

Card apps count what you have.
CardYield counts what it cost you.

Every other card app treats breaks as a black box. You buy 4 PYP slots, get 3 base cards back, and the app shrugs. CardYield tracks the whole pipeline: wax → break → singles, with real cost basis math end-to-end.

  • Log a case break with spots + total cost.
  • Add the cards that came out and link each one to its break.
  • See real P&L: sunk in breaks vs cards received.
  • Portfolio dashboard rolls it all up.
