One man, one app, and $27 billion of your forgotten money.

Open your junk drawer. Some of that $27 billion is yours. Christian Sorensen built CardCue Pro to help you find and use your share. He is also the designer, the marketer and, when something breaks, the support desk. One scan reads a card's brand, balance, barcode, PIN and expiration date. Everything goes in one place: gift cards, store credit, punch passes and memberships. Walk near a store where your money is waiting, and your phone speaks up, even with the app fully closed. At the register, your iPhone or Apple Watch shows the barcode. Free for three active cards, no account. There is even a national day for it: National Use Your Gift Card Day, the third Saturday in January, which lands on January 16 in 2027.
