KeyStacker: Loyalty Wallet

Keep every loyalty, rewards & membership card in one private app. Scan once, show the barcode at checkout. Works fully offline, no account, Face ID locked.

Stack your cards, ditch the clutter.

Key Stacker turns your phone into a single, tidy wallet for every loyalty card, membership, gym pass, and library card you carry. Snap the barcode once and it's ready whenever you need it — no account, no sign-up, no internet

Add cards in seconds Point your camera at any barcode or QR code and Key Stacker captures instantly. Supports all the common formats — QR, PDF417, Aztec, Data Code 128/39/93, Codabar, EAN, UPC, and more — so if a store can scan it, you can stack it.

Built to scan Open a card and Key Stacker jumps to full brightness and shows the code big and crisp. Pinch to resize it, rotate wide barcodes to fill the screen, let any reader pick it up on the first try. Each card remembers your preferred size.

Stay organized Tag your cards, mark favorites, and search or filter to find the right fast. Add notes, pick an accent color, and snap photos of the physical card for reference.

Yours and private Everything lives on your device. Lock the app behind Face ID, hide it from the app switcher, and back up or restore your whole wallet with a single shareable file.
